D-Tube™ Dialyzers

Easy to handle, D-Tube™ Dialyzers are in a centrifuge tube format with dialysis membrane windows for buffer exchange. Just add or remove your sample with a standard laboratory pipette and obtain >97% sample volume recovery. Available molecular weight cut-offs range from 3.5 to 14 kDa and there are six volume capacities: mini (10–250 μL), midi (50–800 μL), maxi (100– 3000 μL), and mega (10, 15, and 20 mL). The regenerated cellulose membrane is sulfur- and heavy metal-free. Each kit contains 10 D-Tube™ Dialyzers (mega kits also offered in 50/pk) and one floating rack to hold devices in the exchange buffer. Use D-Tube™ Dialyzers for electroelution using the optional accessory kit.
