Gel Filtration (SEC) Media

Gel filtration (or called size exclusion chromatography, SEC) is a well-proven versatile technique, which is widely used for separating molecules based on their sizes (molecular weights).

SepFast range of gel filtration media has a balanced design to offer high recovery and high selectivity according to individual applications.

The base matrix is made of agarose or a composite of agarose and dextran that have been highly cross-linked. The media is very stable to most of the chemical conditions experienced in bioprocessing industry.

Suitable use for each high selectivity gel filtration media

SepFast SEC 6-600KDa; SepFast SEC 3-70KDa; SepFast SEC 1-10KDa – Preparative grade use, equivalent to Superdex 200 pg, Superdex 75 pg and Superdex 30 pg, respectively.

SepFast 1000-6000Da; SuperSpin Desaltor; SuperSpin Concentrator – Good for fast desalting of protein samples or other
biomolecules.

SepFast 4B; SepFast 6B – For purifying very large molecules (e.g. plasmids, viruses etc) under gravity or very low pressure.

SepFast CL-2B; SepFast CL-4B; SepFast CL-6B – For purifying very large molecules (e.g. exosomes, plasmids, viruses etc) under gravity or low pressure.

SepFast 4 High Flow; SepFast 6 High Flow – For purifying very large molecules (e.g. plasmids, viruses etc) at process scale under pressure.
