Spin Columns and Gravity-flow Columns
Research Products International Corp Zymo-Spin I Columns, Uncapped, 250/pk
The Zymo-Spin I Fast-Spin column can be used either in microcentrifuges or on vacuum manifolds for the purification of DNA and/or RNA. The Zymo-Spin I features durable polypropylene construction and contains a unique silica-based matrix that allows purification of up to 5 µg DNA or RNA in ≥ 6 µl eluate. Capacity is 800 µl.
Epoch Life Science Inc EconoSpin® Silica DNA Midi Columns (50/PK)
Silica membrane columns for large scale non-transfection grade plasmid DNA extraction. 250 ug plasmid DNA binding capacity. 6.5 ml bed volume. Fits into most 15ml centrifuge/culture tubes. Requires proper centrifuge and rotor. Less expensive and faster alternative to anion-exchange columns. For DNA used for cell transfection please try our anion exchange columns (1970050) instead.
Sigma Aldrich Fine Chemicals Biosciences LiposoFast Liposome Factor1EA
Fast efficient formation of uniform-sized unilamellar liposomes. The principle is simple a lipid emulsion is repeatedly extruded through a porous polycarbonate membrane forced back and forth by specially modified gas-tight syringes attached to the membrane support capsule. With the syringes provided unit has 0.5 mL capacity and virtually zero dead volume. Membranes from 100 to 400 nm pore size available.
