BioAssist G2SWxl, G3SWxl and G4Swxl are made of PEEK housing material to reduce sample absorption to stainless steel or glass. These columns have the same attributes as the corresponding stainless steel columns (TSKgel G2000SWxl, G3000Swxl and G4000SWxl). Widely considered the premium columns for analyzing biopolymers by GFC, TSKgel G4000SWxl columns feature high pore volume per unit column volume, low sample adsorption and excellent column efficiency, all contributing to unsurpassed sample resolution. With 8 micron particles and 450? pores, TSKgel G4000SWxl provides the largest exclusion limit and the widest fractionation range. It is an excellent choice for pegylated proteins or glycosylated biomolecules. The fractionation range is applicable for globular protein samples up to 7 million Da.
