Desalting / Buffer Exchange
Based on the principle behind size exclusion chromatography, cross-linked neutral polysaccharide particles with very tight pores are packed into spin columns or preparative chromatography columns for rapid desalting and / or buffer exchange.
SuperSpin Desaltor and SuperSpin Concentrator are suitable to processing up to 100 µl samples at high speed.
SepFast SEC 1000-6000Da media and pre-packed preparative columns (1ml, 5ml, 10ml, 20ml, 53ml etc) are suitable to desalt/buffer exchange increased volumes using syringe or pump.
