Centrifuge Tubes - Pressure-Fugation News

Wolflabs Vivaproducts :: New category 'Centrifuge Tubes - Pressure-Fugation'

Models include; Vivacell 70, Vivacell 100, and Vivacell 250

Introduction
Vivaproducts Vivaspin 70 pressure-fugation centrifuge tubes from Wolflabs. Ultrafiltration unit for sample concentration with highest process flexibility: Centrifugation or centrifugation of pressurized units, as well as pressure filtration in stationary benchtop mode or with gentle shaking.

Features and benefits
- Easy to handle
- High flux PES membrane
- Vertical membrane design for ultra fast concentration
- High retentate recovery > 90 %
- Total process flexibility
- Universal rotor compatibility

Introduction
Vivaproducts Vivacell 100 pressure-fugation centrifuge tubes from Wolflabs. Vivacell 100 is the latest member of the Vivacell family and bridges the volume range between the Vivacell 70 and the Vivacell 250. The patented vertical membrane design allows highest performance and unmatched flexibility.

Features and benefits
- Vivacell 100 is a unique and innovative concentrator for volumes from 20ml to 100ml, which utilizes pressure, centrifuge or pressure-shake to rapidly concentrate even samples with very high particle loading.
- Vivacell 100 is designed for centrifugal concentration of samples up to 100ml which makes it the largest centrifugal unit available. At the same time, the new construction design allows for maximum centrifugal force of 4,000x g to be used for even faster concentration.
- Like the smaller Vivacell 70 unit, Vivacell 100, when used as a centrifugal device, fits only into swing bucket rotors accepting 250ml bottles.
- Vivacell 100 units can also be used for single or extremely sensitive samples in the pressurized mode only and left on the bench or placed on a laboratory shaker for faster concentration. It can also be kept in a pressurized mode in the refrigerator. Handling is made easy by use of quick connectors. In whichever mode Vivacell 100 is used, the vertical membrane design inhibits membrane fouling while the builtin dead stop impedes concentration to dryness and loss of sample.

Introduction
Vivaproducts Vivacell 250 pressure-fugation centrifuge tubes from Wolflabs. Gas pressure unit with exchangable ultrafiltration inserts. Operated in stationary benchtop mode or with gentle shaking for increased performance.

Features and benefits
- Easy to handle
- High flux PES membrane
- Vertical membrane design for ultra-fast concentration
- High retentate recovery > 90 %
- Unit reusable, only membrane insert needs to be replaced
