the QuikPrep ElectroPrep Electrodialysis System is an extremely versatile patented sample preparation technology that is capable of separating samples by both size and charge. It is ideal for the rapid purification of proteins, nucleic acids, carbohydrates and other biomolecules. Membranes of different molecular weight cut offs (MWCO), from 100 to 300,000 daltons, can be used for selective buffer exchange, dialysis, filtration, concentration, fractionation and elution. 

The electroprep system provides faster dialysis times due to movement of charged molecules in an electric field during dialysis, thus combining electrophoresis with dialysis. With a run time of 5 to 10 minutes, electroprep provides speed and convenience, even at the very low currents (5 to 10 mA) used with this system.
