Microdialyzer Systems

Simultaneously dialyze small sample volumes with minimal protein loss - in less than one hour!

Many dialysis methods are time consuming and result in substantial sample loss - a critical concern when dealing with small sample volumes. Pierce Microdialyzer System offers quick, simple methods for sample desalting or buffer exchange. This unit require only about an hour to complete the dialysis procedure, and minimize the loss or dilution of precious samples. It virtually eliminates the need for awkward, time-consuming dialysis prodedures.

The Pierce Microdialyzer System is ideal for dialyzing small samples. Microdialyzer System 100 is designed for the simultaneous dialysis of 12 x 20-100 µl sample volumes. This Microdialyzer System is equipped with a lid to prevent evaporation of the sample, and a unique inlet/outlet system for easy buffer exchange.

The Pierce Microdialyzer System offers minimal protein loss and excellent sample recovery. In addition, Delrin Well Plates are available for autoclaving applications with the System 100. Pre-cut and pre-framed cellulose acetate membranes of varying molecular weight cut-offs are also available for added convenience.

Applications:

Purifying membrane proteins
Removing protein modification reagents and crosslinkers
Removing oligosaccharides from protein solutions
Dialyzing prior to electrophoresis
Exchanging, collecting, and/or analyzing buffer during dialysis
Blotting for immunochemistry

Highlights:

Wide range of MWCOs available, 1K to 50K
Handy lid to prevent evaporation
Stir bar to increase dialysis efficiency
Unique one-way valve system to provide more efficient regulation of buffer exchange
Improved design allows access to dialysate chamber and channels "air bubbles" to a vent valve
