Ultra Centrifugal Filter 4ml,Desalting Columns with PES Membrane, Polypropylene Container with Graduated and Screw Cap

Polyethersulfone membranes exhibit very low binding to proteins and nucleic acids ,offer high flow rates for faster filtration ,designed to concentrate and desalt low volume protein and nucleic acid solutions,recovery >90%

 The vertical membrane design and thin channel filtration chamber minimizes membrane fouling and provides fast, high speed concentrating, even with particle laden solutions

 The anti-filtration dry-lock design prevents damage to samples caused by excessive centrifugation, ensuring stable and reliable experimental results

 The molecular weight cut off (MWCO) or nominal molecular weight limit (NMWL) of the membrane filter should be ½ to ⅓ of the size of target macromolecule retention

 Application for Concentrate and desalt proteins,nucleic acids,buffer exchange or desaltingof chromatographic components,harvest biomolecules from culture media,removal of primers, adapters or molecular markers from the reaction mixture
