Stainless Steel Hydrophilic Size Exclusion HPLC Column with Silica Packing Customized OEM & ODM
Product Description
Features
The chromatographic packing adopts a unique chemical bonding technology, in which hydrophilic polymers and hydrophilic diol functional groups are bonded on the surface of silica gel. The double bonding mechanism makes the non-specific adsorption of water-soluble biological samples extremely small, which can be widely used in the separation and determination of water-soluble polymers and biomolecules.
