FAN BOXES

Coy Laboratory Products catalyst boxes come in two styles, heated and unheated.

DIGITAL, HEATED

UNHEATED
The unheated catalyst box is designed for those laboratories which do not require elevated temperatures in their chambers. It functions in a manner similar to the heated box. Air is quietly drawn in and up through the desiccant and catalyst Stak-Paks*, thus ensuring a complete mix of the atmosphere to control humidity and oxygen levels.

GAS LEAK DETECTOR

Part #: 7000-050

Manufactured for Coy Laboratory Products by Quantum Inc., this is a sensitive electronic instrument that can detect the presence of a variety of gases. Its ability to detect the hydrogen found in anaerobic gas mixtures, even at very low concentrations, makes it useful for finding leaks in anaerobic chambers, both at start-up and during regular maintenance.

The palm-sized Gas Leak Probe responds to minute concentrations of certain gases by emitting a geiger-counter like sound that increases in speed as you pin-point the source of leaks. There are no meters or lights to be monitored. In addition to its use with anaerobic gas systems, it can be used in detecting leaks in other gas systems carrying most combustible gases as well as certain refrigerant gases.

Fyrite Tester Part #: 2550-010

Other Modifications

Coy Laboratory Products, the leading supplier of flexible controlled-environment chambers, has available a modular chamber concept incorporating a new one-piece cast airlock and an innovative microprocessor-based automatic controller.

The modular approach allows multiple chambers to be chained with a three-port airlock, which increases ease of operation and significantly reduces space requirements and cost. A new casting process eliminates pinhole leaks sometimes found in older cast units. Leaks are now a thing of the past.

Features:
FRONT LOADING... makes the airlock easier for the operator to use, and more importantly, eliminates the need for extra clear space at the end of the chamber for opening the door. The airlock end of the chamber can now be right against a side wall.

RECTANGULAR SHAPE... has more usable space. The flat floor prevents bottles and flasks from tipping over, taller jars will pass through upright.

SYMMETRICAL DESIGN... allows the airlock to be used at either end of the chamber, or
with multiple chambers.

SPECIFICATIONS:

CONSTRUCTION - Body and door flanges are precision one-piece cast aluminum. Doors are 3/4" clear acrylic. Door closures are lever-operated with cam actuation for high, uniform sealing pressure.

DOOR OPENINGS - 12" high x 9" wide (30.5 x 22.9cm) Interior-- 13.4" high x 13.6" wide x 13.5" deep (34.O x 34.6 x 34.6cm)

ELECTRICAL - Maximum with vacuum pump 115V +/- 1O%/60 Hz, l5amp. 220V +/- 10%/50 Hz, 7.5amp.

VACUUM PUMP - (Included with all airlocks when ordered as original equipment) 7.2 CFM (3.4 cu, cm/sec), oil-less rotary vane, 26" Hg (0.89 kg/sq. cm) ultimate vacuum capability, 1/2 HP motor. 110V/6OHz, 220V/50 Hz. In-house vacuum systems must meet 4 CFM capacity to 24 in, Hg minimum requirements.

For Custom Aluminium and Vinyl Chamber

The Airlocks timer is preset at the factory but you can adjust it to your needs. Longer purge times for stricter applications. The chamber gas mix maintenance system is also factory set, but again, may be adjusted. With this system, the gas mix is automatically injected into the chamber for the selected time period on the selected time interval to easily maintain a safe, adequate hydrogen content. Any excess pressure is exhausted from the chamber by a pressure relief valve.

This model incorporates all the features of the manual air lock and adds the convenience and economy of automatic airlock cycling. A single push of a button frees the operator for other tasks while the airlock automatically cycles through a programmable sequence. Gas savings are realized by perfectly consistent vacuum and pressure levels.

Front-panel lamps indicate cycle progression, airlock status, and any fault condition, such as open door, empty gas cylinder, etc. An audible alarm emits a pleasant beep at cycle completion and other different sounds to indicate fault conditions.

All utility connections for electricity, vacuum pump hookup, and gas connections, as well as manual operation switches are at the rear of the airlock. The manual switches are intended for use when first setting up a chamber or to override the automatic control. They are operational even with the automatic control circuitry totally removed.

Microprocessor control not only enhances reliability, but allows any user-specified sequence to be programmed into the unit. The sequence(s) can be changed later for a nominal charge.

Custom, modular, affordable laboratory chambers provide isolation, containment, humidity, temperature and oxygen control. These epoxy-coated, aluminum chambers are designed to your individual needs by selecting components from numerous interchangeable parts and accessories.

PVC CONSTRUCTION The chambers are constructed of heavy duty, flexible PVC mounted on a rigid base. Thickness ranges from 20 to 40 mils.

RELIABLE AND DURABLE All seams are radio-frequency welded to produce a one-piece bag that will withstand many years of service.

MANY APPLICATIONS In addition to medical laboratory applications, Coy controlled environment chambers have found other applications in industry due to their design and economy. These include microwelding, handling of hazardous materials, dry atmosphere, optical and electronic equipment assembly.

ECONOMICAL Not only are Coy chambers less expensive than many comparable rigid box chambers, but gas requirements are lower, keeping operating costs at a minimum.

REDUCES OPERATOR FATIGUE The optically clear vinyl greatly increases operator vision, and the gloves do not fight back when entered, as in rigid chambers. In addition, there are no rigid ports to interfere with and consequently tire the operator's arms.

MODULAR DESIGN Coy systems are designed to be expandable and easily modified through the many options available.

3 STANDARD SIZES Chambers are available in three lengths: 36", 59" and 78" (91 cm, 150 cm and 198 cm). All are 32" (81 cm) deep and 40" (102 cm) tall.

Model 10 Gas Analyzer for Oxygen/Hydrogen

This patented analyzer constantly monitors both oxygen and hydrogen levels within a chamber at a fraction of the cost of two separate analyzers. The unit monitors both oxygen and hydrogen directly from the chamber atmosphere. The analyzer’s constant LED display keeps users continually informed of minute changes in oxygen and hydrogen levels and provides the operator the opportunity to make adjustments. If there is an incorrect gas mix or a problem with valves and regulators, users are alerted by visible and audible alarms. Use of the Model 10 Gas Analyzer can typically pay for itself. For example, labs can use less-expensive, non-certified gas mixes by employing the Model 10. This enables labs to reduce operating costs while also protecting against possible gas mix concentration issues. Voltage outputs are available as an upgrade to new and existing Model 10 units. The outputs allow the readings to transfer to a data logger, chart recorder or computer program, which is especially helpful when 24-hour documentation is required.


Gas Injection System

Coy’s automatic gas injection system frees the operator from worrying about having enough hydrogen to maintain an anaerobic environment. The system injects the hydrogen gas mix into the chamber on a fixed time schedule for a fixed time period, allowing users to leave the chamber unattended for days at a time. Laboratories achieve improved performance and ease of use when the gas injection system is teamed with the Coy Model 10 Gas Analyzer.

Technical Information

Glove boxes - Hypoxic - Aluminium - Coy

The only complete system available for hypoxic/hyperoxic tissue culture and live animal studies that allow CO2 incubation AND sample manipulation conveniently in a heated oxygen controlled atmosphere.

Through a strategically positioned oxygen sensor and controller the Coy Hypoxic Glove Box can maintain a uniform gas concentration throughout the chamber and optimum control. As gases are required in the glove box, they are introduced through a unique gas tube shower system which, along with the internal fan, provides the circulation required for uniform gas distribution and fast response of the controller. To allow for the relief of pressure induced by gas addition, special check/bleed valves are installed in the glove box.

Temperature Control (option) Units can either be heated or unheated or unheated with a separate Incubator. A solid state heater provides reliable, stable temperature control with digital display and controls in both our Incubators and Heated Glove Boxes.

CO2 Control (option) All COY Hypoxic units can be equipped with optional CO2 Controls. A revolutionary controller and sensor, allows for precise control and monitoring of CO2 gases inside the glove box. The sensor relays information to the controller which then opens the appropriate Solenoid controlling a CO2 or N2 Gas to equilibrate the CO2 levels inside the glove box. The digital display allows the user to monitor the CO2 Levels constantly.

Humidity Control (option) COY offers a few different ways to control the humidity of the glove box depending on the application. Some heated units have a built in solid state dehumidifier with digital displays and controls. Typically the Solid State Automatic Dehumidifier is recommended but for some low volume/small size animals a more affordable desiccant drying system may be utilized. Cell Culture units typically are provided with an optional Humidified Incubation Box (high humidity box within the glove box) to prevent samples from drying out however since these are not air tight the moisture eventually escapes into the glove box atmosphere so the Solid State Dehumidifier or Desiccant drying system is used to maintain ideal relative humidity.

Cell Culture Units Cultures are incubated in the heated, humidified, gas controlled (up to 100% O2) incubation box which resides inside the glove box. The glove box is heated and gas regulated, but not humidified. This allows samples to be analyzed with delicate equipment that would be damaged by high humidity. More importantly, controlled oxygen conditions are maintained in the sample analysis area. Tests that could not be performed with a bench top enclosure and CO2 incubator because of the biologically fast reaction to ambient oxygen can now be performed.

Live Animal Containment Depending on the labs animal care requirements the units can be heated or unheated. Most units for live animal containment will also require the COY Animal Filtration System to remove the animal waste byproducts, these units can be automatic or manual, with the manual based on a simple protocol the lab establishes, automatic units are based off the CO2 levels. The Animal Filtration system is a closed loop circuit with a pump drawing the glove box atmosphere out and through the filters (Carbolime and activated carbon) and back into the glove box.

Airlock Sizes for Live Animal Containment Due to the variety of number and size of animals kept in these glove boxes COY manufactures each unit to specifically match a labs cage size to the airlock providing optimum efficiency.
 

Technical Information

Glove boxes - Humidity Controlled - Aluminium - Coy

These units allow the user to control interior humidity levels above or below ambient conditions. All units are equipped with the latest in Humidity Sensor technology and Ultra Sonic Humidifier and either Desiccant Drying System or a Dry Gas Purge System.
STYLES Two standard styles available, a clear Polycarbonate unit that features a lower cost to purchase, and relatively low cost to customize. The Aluminium units while more expensive on initial purchase are a longer lasting, sturdy build that with the addition of tempered Glass can be used in highly corrosive chemical use. Polycarbonate units have 4 standard sizes and Aluminium units have two.

AUTOMATIC CONTROL The automatic controller provides monitoring and control of the relative humidity. It activates the necessary system (dehumidification for humidification) when the moisture level deviates from the adjustable set point. Flow rates, sensor position circulation, and orifice positions were all considered in the design to maximize control capabilities and humidity uniformity across the glove box. Since this is a closed loop circulation system, an inert gas environment can be maintained in the glove box while controlling the humidity.

HUMIDIFIER The Ultra Sonic Humidifier vibrates the water in the reservoir to provide a cloud of mist that is pushed into the glove box from the pump system. At the same time air is pulled out of the glove box and circulated through the water reservoir, completing the Humidification System's closed loop circuit. Water reservoir is equipped with Self Sealing Quick Disconnect inlet for refilling under sealed conditions.

DRYING SYSTEMS Two systems are available to dry these Humidity Control Glove Boxes a Desiccant Drying System (Pictured above) and a Dry Gas Purge System. The Desiccant System is standard however the Dry Gas Purge System can be substituted at no extra cost. The Dry Gas Purge System allows for a lower attainable humidity level 3% (1% using special dry gas) vs 5% for the desiccant System. The Gas Purge System is also cleaner, provides faster drying times and requires less maintenance (Desiccant needs to be rejuvenated). The Desiccant Drying system can be a lot less expensive to operate. The two systems can also be used to work together to minimize the cost of the dry gas purge system.

GLOVELESS SLEEVE All units are equipped with gloveless sleeves to allow superior handling of interior samples. However the moisture from skin does influence Humidity levels below 15% Rh and for these applications the user may need to operate with gloves which can easily placed over COY over the gloveless sleeve cuff. (Click here to see Gloveless Sleeves)

TRANSFER CHAMBER OPTION All units have an optional pass thru chamber (air lock) available. This enables transfer of equipment and samples with out drastic changes to the interior environment.

Glove Boxes - Anaerobic - Vinyl - Coy

DESIGN THEORY

The Vinyl Anaerobic Chambers provide a strict anaerobic atmosphere of 0-5 parts per million (ppm) using a palladium catalyst and hydrogen gas mix of 5%. The heavy duty vacuum airlock allows sample transfer without changes to the internal atmosphere. The Programmable airlock allows the user to tailor an interchange sequence ideal for their lab experiments.
The Flexible nature of the unit allows for the user to reach deeper and higher into the unit. And the flexible nature of the unit combined with padded base and larger glove ports allows for greater ergonomics vs. a rigid glove box. The optically clear vinyl greatly increases operator vision, and the user does not encounter any glove "fight back" as the flexible nature allows the entire glove box to give with changes to internal volume.

PVC CONSTRUCTION

The glove boxes are constructed of heavy duty, flexible PVC mounted on a rigid base. Thickness ranges from 20 to 40 mils.

RELIABLE AND DURABLE

All seams are radio frequency welded to produce a one piece bag that will withstand many years of service.

AIRLOCK

A single push button begins the automatic sequencing of oxygen reduction within the airlock. Airlock can be adjusted to optimize the settings for the operation of the lab from experiment to experiment including number of cycles to level of the vacuum.

ECONOMICAL

Not only are Coy vinyl glove boxes less expensive than many comparable rigid glove boxes, but gas requirements are lower, the flexible glove box does not require any pressure relief or vent for excess gas keeping operating costs about 1/3 less than a rigid glove box of comparable size.

MODULAR DESIGN

Coy glove boxes are designed to be expandable and easily modified through the many options available.

CUSTOM SIZES AND CONFIGURATIONS

Available at minimal additional cost, and accessories are available to economically create special configurations.

Technical Information

Glove Boxes - Anaerobic - Aluminium - Coy

Rigid Anaerobic units

Rigid Anaerobic units can be manufacture from economical Polymer or the sturdy Aluminium.
The Aluminium units are ideal for labs with chemical resistance needs, due to the ability to upgrade the standard polycarbonate viewing screen to a Tempered Glass, and the Glove Port Panel to an Aluminium style. Aluminium Anaerobic Chambers also have the advantage to upgrade to a gloveless style.

The Polymer units are an easy and economical way to get started with an Anaerobic Chamber. Equipped with a purge only airlock these units are typically half the cost of the other style Anaerobic Chambers. It is important to keep in mind that while less expensive to purchase it may cost more to operate due to the purge only application of the airlock, but in a low volume lab this may be just the unit for you.

Anaerobic Atmosphere The COY Anaerobic Chambers provide a strict anaerobic atmosphere of 0-5 parts per million (ppm) using a palladium catalyst and hydrogen gas mix of 5%. Air is circulated through a Fan Box which is designed to house the wire mesh container of catalyst called a Stak-Pak. The process of removing O2 from the atmosphere can produce moisture so often times these Stak-Paks are filled with desiccant and stacked on top of the Catalyst. The airlock allows sample transfer without changes to the internal atmosphere by equilibrating the O2 levels through a Vacuum and Purge Procedure (Purge only for the Polymer Units).

Gloveless Anaerobic Chambers

Gloveless Anaerobic Chambers offer the operator a convenient glove-free ability to handle and inspect samples under low oxygen (0-5 ppm) conditions. A special cuff and sleeve-vacuum system allows the operator to work barehanded (or with surgical gloves) inside the glove box. After the operator inserts their arms into the gloveless sleeves, a foot operated sleeve-vacuum system creates an inert atmosphere in the sleeves prior to removing the Arm Port Plugs. This permits the operator's arms to enter the glove box without compromising the anaerobic chamber atmosphere. Tactile efficiency is improved. The Arm Port Plugs are used to seal the glove box while it is idle.
Units operate similar to other COY anaerobic chambers using a palladium catalyst to remove O2 through a H2 Gas Mix (5%). Equipped with an airlock to establish low O2 conditions prior to transferring samples and instrumentation in/out of the work area.

All COY Polymer Gloveless Anaerobic Chamber include a built in heating system (up to 40° C) and Glove Box Dehumidifier to maintain proper moisture levels through automatic digital control.

From the two basic glove box styles, choose the design which suits your laboratory volume. Select either the compact, all clear, polycarbonate style with automatic purge airlock, or the larger aluminium glove box available with an automatic vacuum airlock.

HYPOXIA CHAMBER

Incubator Chambers - CO2 And Multigas - Coy

The Hypoxic Cabinet allows you to quickly and conveniently incubate samples (animal or cell culture) at reduced or elevated O2 levels. Cell Culture cabinets are designed to fit into an existing incubator for longer term incubation. The System
offers you the ability to change the O2 levels automatically with a sensor monitoring the conditions constantly and the Controller adjusting for changes to the desired set point by purging N2 gas or optionally O2 gas for Hyperoxic operation.
This avoids the purchase of costly gas mixes to satisfy a complete range of O2 levels.

Complete System Includes:
• O2 Controller + Sensor
• N2 Gas Regulator
• Pressure relief valve
• 2 sensor ports
• Circulation Fan
• Gas Inlet
• Sliding Shelf(s) for Cell culture units

The Hermetic Seal insures that even with the controllers unattached you can maintain set O2 levels for long periods of time. This also translates into better gas consumption as the “diffusion rate” is significantly reduced over a semi sealed cabinet.

System Options
• Heaters for precise temperature control.
• CO2 Control System (Sensor, tubing and gas regulator included) 0-20% control
• Tray for containment of water/desiccant or animal waste byproducts removal
• Cycling between multiple O2 set points automatically
• Voltage Output for readouts sent to computer or other such program.

Technical Information

Glove Boxes - Dry - Polymer - Coy

Coy Dry Glove Boxes control and maintain humidity levels below ambient conditions, achieving a humidity level of 5% or lower through either a desiccant system for removing moisture or through a dry gas purge system, typically utilizing dry nitrogen or argon. Control is through a revolutionary sensor and monitor/controller providing precise control in .1% increments, with tuning features.
STYLES Two standard styles are available: a clear Polycarbonate unit that features a lower cost to purchase, and relatively low cost to customize. The Aluminium units while more expensive on initial purchase are a longer lasting, sturdy build that with the addition of tempered Glass can be used in highly corrosive chemical use. Polycarbonate units have 4 standard sizes and Aluminium units have two.

AUTOMATIC CONTROL The automatic controller provides monitoring and control of the relative humidity. It activates the necessary system (dehumidification for humidification) when the moisture level deviates from the adjustable set point. Flow rates, sensor position circulation, and orifice positions were all considered in the design to maximize control capabilities and humidity uniformity across the glove box. Since this is a closed loop circulation system, an inert gas environment can be maintained in the glove box while controlling the humidity.

DRYING SYSTEMS Two systems are available to dry these Humidity Control Glove Boxes a Desiccant Drying System (Pictured above) and a Dry Gas Purge System. The Desiccant System is standard however the Dry Gas Purge System can be substituted at no extra cost. The Dry Gas Purge System allows for a lower attainable humidity level 3% (1% using special dry gas) vs 5% for the desiccant System. The Gas Purge System is also cleaner, provides faster drying times and requires less maintenance (Desiccant needs to be rejuvenated).
