Sepax Technologies Inc Sepax HPLC Column Bio-C4, 3 µm, 300 Å, 4 x 10 mm
Monomeric and fully endcapped Bio-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. Bio-C4 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of intact proteins, and natural and synthetic peptides.
Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP10, Guard cartridge with holder, 2 x 10 mm
Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.

Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 µm, 300 Å, 2 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
