Introduction
New Libra S2 series colorimeter from Biochrom has been added. The Libra S2 colorimeter is a small, robust, easy to use instrument that has been designed with both the student user and “field” user in mind. It is ideal for teaching the principles of science and analysis in schools and secondary education colleges, as well as being rugged enough for measurements in, for example, remote location health clinics where simple diagnostic tests need to be made. The instrument surface is designed for ease of cleaning and decontamination. The instrument measures in Absorbance and % Transmission mode as well as in simple kinetics, enabling changes in Absorbance over time and reaction rates to be determined (readings are taken approx. every second). It may be used to cover the 400 – 700 nm wavelength range as it has an integral, colour coded rotating wheel containing filters at 440, 470, 490, 520, 550, 580, 590 and 680nm. These are made from coloured gelatin and are encased in glass, so that the instrument can be used in “tropical” conditions. A filter is selected by moving the wheel until the required wavelength is displayed in the window above the cell compartment.

Features and benefits
- Designed with student, QC and field users in mind
- Rugged, portable and easy to use
- Extremely versatile
- Rechargeable battery version available

Introduction
New Model 260 series colorimeters from Sherwood Scientific have been added. The Model 260 Series Colorimeters offer features not elsewhere available and provide solutions to the requirements of quality control, water testing and also the clinical chemist with low sample runs. Both Models can be powered from a 12V car battery so can be utilised in locations where the power supply cannot always be relied upon.

Features and benefits
- The Model 260 replaces the previous CHROMA Model 257 Colorimeter and incorporates full programmability, allowing up to 100 methods to be installed by the operator. This permits semi-automatic operation; the user need only insert the prompted filter. An RS232 output allows the use of a serial printer and every result, blank and calibration is time stamped. The unit allows quick Absorbance and Transmission measurements with Auto-Zero, Concentration with Standard Solutions or Factor, as well as the new Kinetic Reaction Rate and End Point methods.
- The Model 260 Series Colorimeters have two options to control the temperature of reactions. The low cost option is to use external temperature control by means of solid block heating. The software built in to the 260 Series Models includes the setting of incubation (or lag time) and measuring time. Towards the end of these times, the user is alerted to return the cuvettes containing the blank, sample or calibrant to the Colorimeter by means of a buzzer. The relevant reading is taken and the cuvette is returned to the heating block to complete the rest of the test.
- With a working wavelength range spanning 325 to 750 nm, the Model 260UV can be utilised for a wide variety of clinical and non-clinical chemistry tests. The Model 260UV is supplied with a set of eight drop in gelatine filters together with a 340nmm interference filter and a heated cuvette holder for operation at 37°C if necessary. Each unit is thereby supplied capable of performing colorimetric tests across the whole visible wavelength spectrum and in part of the near UV region.
