  • Part Number: AO-02906-70
  • Package Quantity: EACH
This ready-to-use separation device delivers the efficiency of dynamic dialysis to significantly reduce dialysis from 1 to 2 days down to 4 to 12 hours. The Tube-A-Lyzer incorporates biotech-grade CE tubing that separates the sample chamber from the surrounding flow-through buffer chamber. The separate sample port provides easy access for sample loading, sample recovery and in-process testing. The housing and end caps are polycarbonate (PC) with 3/16" (6 mm) barb inlet/outlet ports. Connect the housing to a buffer source and a waste collection vessel, or discharge directly to drain. Tube-A-Lyzer is non-pyrogenic and can be gamma sterilized (25 kGy). Dry packaged with 20% glycerin.

  • Package Quantity: PACKAGE
Hollow fiber membranes feature a high surface-area-to-volume ratio making them very efficient and ideal for samples smaller than 0.5 mL. Membranes are made from a biologically inert, regenerated cellulose impregnated with glycerol. Individual fibers are ideal for the recovery or introduction of micro-quantity biologicals or pharmaceutical materials into a localized tissue environment. Inject a sample into the lumen with a syringe, dip the ends of the fiber into epoxy, allow to dry, and then implant.

Other Picture


MicroEquilibrium dialyzer, 100 µL chamber volume Feature

  • MicroEquilibrium Dialyzer
  • An unique, reusable product for studying protein binding to small molecules and ions
  • High sample recovery, leakproof and easy to use
  • Model: NP 74-1608
  • Manufacturer number: NP 74-1608
  • Part Number: AO-02896-04
  • Package Quantity: EACH
Reuse MicroEquilibrium dialyzers many times over— autoclavable PTFE construction makes them easy to clean. Dialyzers can be used with three chambers instead of two, which lets you obtain results without waiting for equilibrium, reduces assay time, and lets you determine which of two samples has a higher binding affinity. When dialysis is complete, the chambers can be opened at each end to extract the sample for analysis. The entire system can also be placed in a thermostat for temperature-controlled dialysis. Membranes are required; order separately.
