Disposable Equilibrium Dialysers

DispoEquilibrium Dialyzer, for volumes of 25 µl to 75 µl


DispoEquilibrium DialyzerTM

The DispoEquilibrium Dialyzer is a single-use product for interaction studies and is currently the only such device on the market.

The DispoEquilibrium Dialyzer is leak-proof and provides high sample recovery (almost 100 percent). This system is designed for one-time use with samples such as radiolabeled compounds, avoiding the hassle associated with cleaning the Dialyzer after use. Each chamber has a capacity of 25 to 75 µl. The DispoEquilibrium Dialyzer utilizes high-quality regenerated cellulose membranes with MWCOs of 5,000 or 10,000 Daltons. Sample recovery is very easy through centrifugation or via removal with micropipettes.

Includes two caps (one black, one white), two 0.65 ml sample tubes per chamber and two pipette tips for delivery/recovery.
