D-Tube™ Dialyzers

Gently and easily dialyze protein or nucleic acid samples using D-Tube™ dialyzers. These devices feature dialysis membrane windows in a capped centrifuge tube format, enabling efficient buffer exchange to remove urea, detergents, salt, and other microsolutes.

Designed with a double membrane, D-Tube™ dialyzers spread the sample over a large area, so that dialysis is complete in 2-5 hours.

Advantages of D-Tube™ Dialyzers

  • Low-binding regenerated cellulose membrane and housing enhance sample recovery
  • Leak-resistant design — no clamps or knots required
  • Screw cap makes it easy to open and close
  • Easily withdraw even submilliliter volumes, from the rigid frame of the device
  • No syringe required to load or withdraw samples. Simply load your sample with standard pipette tip.
  • Float racks of D-Tube™ dialyzers in most standard-sized beakers containing exchange buffer
  • Use D-Tube™ dialyzers for electroelution of samples from agarose or acrylamide

Select the D-Tube™ dialyzer that’s right for your sample.

Select devices are now available on our website. Check back periodically for updates.
