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.

Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.
