Biovision's DiaEasy? dialyzer (6-8 kDa MWCO) can combines two modes of action, 1) dialysis or buffer exchange at sample volumes between 0.1-3 ml and 2) electro-elution of macromolecules from polyacrylamide or agarose gel. They can also be used for several other purposes as shown below. This device allows rapid and high performance at either mode and extracts the macromolecules without any contamination. By changing the caps, provided with the kit, DiaEasy? Dialyzer tubes can easily adjust for dialysis volumes between 0.1-3 ml. The DiaEasy? tube's membrane is ultra-clean, sulfur and heavy metal free and EDTA-treated which makes it suitable for molecular biology experiments. These tubes are autoclaved and bacteria free. The
