Our silica wool is made from pure fused quartz fiber: amorphous, continuous, tangled, white, odorless, with no volatile component and no shot. Length, shape and arrangement of fibers give the wool its curly appearance preventing compression of the padding and improves its desired insulating properties.

6 to 18 mesh. Indicating (cobalt chloride). Lot analysis on label.

Supplier: Thermo Fisher Scientific

This TLC high purity grade silica gel without binder is used for thin layer chromatography plate preparation.

Supplier: Avantor

CW deactivated fused silica retention gap / precolumn. Deactivation mainly for polar solvents.

Supplier: Avantor

Vydac TP was the first range of wide pore media phases developed in the Vydac range and became the industry standard for peptide and protein separations. The large pores of the 300 Å TP silica give polypeptide molecules complete access to the interior of the silica pores.

Our NH₂, CN- and DIOL-modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH₂ plates provide weak basic ion exchange characteristics with special selectivity for charged compounds.

Supplier: Avantor

HMDS deactivated high temperature fused silica retention gap / precolumn. Deactivation mainly for apolar solvents.
