SepTech™ C18 bulk media, designed for high performance separations at high capacity. The two pore sizes, 60 Å and 150 Å, have been optimised to give high capacity for small molecules and larger natural molecules and peptides, respectively.

Supplier: VARIAN

Strongly basic anion exchanger, Cl⁻ form. Moist, light yellow spherules.

Supplier: VARIAN

PL-SCX is a macroporous PS/DVB matrix with a very hydrophilic coating and strong cation exchange functionality. The manufacturing process is controlled to provide optimum density of strong cation-exchange moieties for analysing, separating, and purifying a wide range of biomolecules from small peptides to large proteins.
