Sample Prep Technology Based on Electro-dialysis

The new ElectroPrep System from Harvard Apparatus is an extremely versatile patented sample prep technology based on electro-dialysis. The ElectroPrep can be used for electro-dialysis, electro-elution, electro-filtration, electro-fractionation or electro-concentration for running a sample simultaneously into multiple molecular weight cut off (MWCO) fractions in as little as three minutes. Harvard Apparatus ElectroPrep System supports a broad range of membranes with MWCO of 100, 500, 1K, 2K, 5K, 10K, 25K, 50K, 100K, and 300K Daltons. This ElectroPrep System is ideal for the rapid purification of proteins, nucleic acids, carbohydrates and other biomolecules. With a run-time of 3 to 10 minutes, ElectroPrep provides speed and convenience, even at the very low currents (5 to10 mA) used with this system. The new reusable sample chambers are made of PTFE for high sample recovery and have been redesigned to provide larger membrane surface areas for even faster dialysis rates. These ElecroPrep DIALYZERS are of 50 µl to 1500 µl volume and can be joined with a Union or one or two Link Chambers in different combinations and membranes.
