TSKgel BioAssist G4SWxl

TSKgel BioAssist G4SWxl is the PEEK format of the TSKgel G4000SWxl column. With 8 μm particles and 45 nm pores, these columns provide the largest exclusion limit and the widest fractionation range within the TSKgel SWxl column line. TSKgel BioAssist G4SWxl columns are an excellent choice for pegylated proteins or glycosylated biomolecules. The fractionation range is applicable for globular protein samples up to 7 million Da.

Widely considered the premium columns for analyzing biopolymers by GFC, TSKgel BioAssist G4SWxl columns feature high pore volume per unit column volume, low sample adsorption and excellent column efficiency, all contributing to unsurpassed sample resolution.
