D-Tube Dialyzers Mini, Midi, Maxi, and Mega The D-Tube Dialyzers be used for dialysis and electroelution of proteins, RNA, DNA, and oligonucleotides from polyacrylamide or agarose gels. The disposable, single-use tubes require no syringes, microcentrifuge, or laborious steps to manipulate small sample volumes. The sample is added and removed using a standard laboratory pipet. Available with molecular weight cutoffs (MWCO) from 3.5 to 14 kDa, the D-Tube Dialyzers are designed in four volume capacities: mini (10-250 µl), midi (50-800 micro;l), maxi (100-3000 µl), and mega (10ml, 15ml, and 20 ml). The membrane is ultra-clean, EDTA-treated regenerated cellulose, sulfur- and heavy metal-free. The D-Tube Dialyzers Mini, Midi, and Maxi contain 10 D-Tube Dialyzers and one floating rack that can hold up to four D-Tube Dialyzers. The D-Tube Dialyzers Mega contain 10 or 50 tubes and one or 5 floating racks to hold one D-Tube Mega in the exchange buffer. D-Tube Electroelution Accessory Kit The
