Reusable Multi-Equilibrium Dialysis System

Reusable Multi-Equilibrium Dialysis System

The Harvard Apparatus Multi-Equilibrium Dialyzer provides highly standardized equilibrium dialysis conditions for up to 20 parallel assays. The instrument offers outstanding uniformity of: membrane area, sample volume, degree of agitation.
The advantages of this system are that up to 20 cells can be used simultaneously for rapid dialysis under standardized conditions. Experiments conducted using the Multi-Equilibrium Dialyzer are extremely reproducible and leak-proof and can be performed at a constant temperature.
The dialyzer cells are made of PTFE, an extremely inert material, and will not interfere with the samples. Multiple cell systems are available (5, 10, 15, 20 cells) at various cell volumes (0.2, 1.0, 2.0 and 5.0 ml). The unit can be sterilized by autoclaving and the cells can be filled easily with a filling clamp. Custom systems with alternate chamber sizes, membranes and power supply are available.
