Ready-to-use dialysis devices are all made with our proprietary Biotech Grade CE dialysis tubing, preassembled with volume specific lengths of membrane tubing and designed to maximize convenience, ease-of-use and sample recovery.
Self-contained cylindrical dynamic dialysis device with concentric sample and buffer chamber
Easy to use
Easy loading and recovery with Luer-Lok Syringe. Continuous buffer flow eliminates buffer changes.
Increases the rate of dialysis and can reduce overall dialysis time from 1-2 days to 6-12 hours
Broad MWCO range
6 MWCOs from 0.1 - 100 kD for all dialysis applications from small peptides to large nanoparticles
Achieve 98% sample purity with Biotech CE membrane, no heavy metal and sulfides.
Purification of fragile proteins
Tube-A-Lyzer® is a ready-to-use device that combines single-use convenience with the efficiency of dynamic dialysis to significantly improve dialysis efficiency and can reduce time from days to hours. The unique two chamber-device features a membrane defined sample chamber with a port for easy sample loading and recovery; surrounded by a flow-through buffer chamber for continuous and gentle dialysis. Compared to traditional-static dialysis, the continuous buffer flow increases the mass transfer rate across the semi-permeable membrane to achieve a higher exchange rate and purity in less time.
The Tube-A-Lyzer® easily mounts on a standard lab stand with a tube clamp and connects to a separate buffer source that is continuously pumped in either single-pass or recirculation mode. Two units can be coupled for operating in parallel. (Stand, pump, pump tubing and bracket sold separately)
Available in 2 sample volume sizes (8-10 ml and 25-30 ml) and made with with high purity Biotech Grade Cellulose Ester (CE) membrane in 6 MWCOs ranging from 0.1-100 kD (refer to the Chemical Compatibility table).
