Ready-to-use dialysis devices are all made with proprietary Biotech Grade CE dialysis tubing, pre-assembled with volume specific lengths of membrane tubing and designed to maximize convenience, ease-of-use and sample recovery.
SpectraPor® Float-A-Lyzer® Dialysis Device
The SpectraPor® Float-A-Lyzer® Dialysis Device is a unique and leak-proof, ready-to-use device designed for easy and convenient dialysis of small sample volumes from 1 – 10 ml. The device is made with high purity Biotech Grade Cellulose Ester (CE) membrane in 9 MWCOs from 0.1-1,000 kD. Screw cap lid and included pipette allow for easy loading, in-process testing and sample retrieval without the risk of needle punctures.
Biotech CE membrane exhibits a fair chemical compatibility and tolerates pH 2-9 and temp 4-37 °C. Exposure to most organic solvents is not recommended and should be confirmed on the Repligen Chemical Compatibility table.
FEATURES
- 3 ready-to-use volume sizes (1 ml, 5 ml & 10 ml)
- 9 Concise MWCO’s for better selectivity & separations
- High purity Biotech Cellulose Ester (CE) membrane
