A revolutionary disposable dialysis device designed for the rapid yet gentle dialysis and separation of larger sample volumes; exhibiting higher efficiency as well as product recovery. Available in 6 MWCOs (0.1 to 0.5kD, 3.5 to 5kD, 8 to 10kD, 20kD, 50kD and 100kD) and two sample volume sizes (8 to 10mL and 25 to 28mL).
Tube-A-Lyzer™ is a self-contained ready to use mass transfer system that incorporates a semi-permeable, tubular dialysis membrane inside a clear reservoir housing to separate the sample chamber from the surrounding buffer chamber. The high purity Biotech Cellulose Ester (CE) membrane is dry, impregnated with 20% glycerine, and offers high molecular selectivity. The full length of the membrane tubing has a working volume of approximately 28mL (Special length units for larger or smaller volumes can be made on custom build basis). A female Luer Lock port is located on the top for sample loading, recovery or in-process testing from the membrane enclosed sample chamber. Designed for dynamic dialysis, the housing (buffer) chamber is equipped with 6mm inlet and outlet hose-barb ports that can be connected to flexible plastic tubing (3/16 x 5/16 inch I.D.) for recirculation of a larger buffer volume using a peristaltic pump. Alternatively, the ports can be capped off to facilitate only the buffer chamber for static (standard) dialysis. Multiple Tube-A-Lyzer™ devices can be connected in parallel to create a larger sample volume manifold.
