WA-Ni is a metal affinity chromatography resin pre-charged with Ni²⁺ ions on agarose gels functionalized with NTA, IDA, or TED chelators. It features high binding capacity, excellent selectivity, e...
Functionalized with IDA ligands covalently linked to agarose, WA-Chelating binds transition metal ions (e.g., Cu²⁺, Co²⁺, Ni²⁺, Zn²⁺), which in turn bind to protein residues for purification.
WD-G Series are dextran-based gel filtration media produced via chemical cross-linking. These hydrophilic, porous beads are used for buffer exchange, desalting, and removal of small molecules from ...
WA-CL 6B is a cross-linked form of WA-6B using bifunctional agents. They exhibit significantly improved physical and chemical stability and can withstand autoclaving at 121 °C. Suitable for large b...

Welchrom PSA is an adsorbent similar to NH2. PSA contains two amino groups with pKa values of 10.1 and 10.9. It has a stronger ion exchange capability compared to NH2 solid phase extraction columns...
WA-4B is made from 4% agarose, processed through emulsification, washing, and sieving. Suitable for separation and purification or analysis of polysaccharides, nucleic acids, viruses, and other lar...
WA-4FF is more extensively cross-linked than WA-CL 4B. They offer superior chemical and physical stability, fast flow rates, and autoclave tolerance at 121 °C. Suitable for large-scale purification...
WA-IMAC is an uncharged IMAC resin consisting of cross-linked agarose functionalized with NTA. It can be charged with divalent or trivalent metal ions such as Cu²⁺, Zn²⁺, Ni²⁺, Co²⁺, or Fe³⁺ to int...
