Silica gel irregular 60, irregular 40-63 µm for flash chromatography

Supplier: VWR Chemicals

Glassy, hard, irregular shaped granules with a very high purity of SiO₂ and an internal surface of approx. 800 m²/g. Because of its very large surface area, this silica gel exhibits a high adsorption for water vapour.

Supplier: Avantor

LiChrospher® is a silica available in both endcapped and non-endcapped C8 and C18 phases.

Supplier: VWR Chemicals

Our silica gel yellow/blue is used where products need to be protected from humidity during storage and transportation. The colour changes from yellow to light blue when saturated.

Supplier: Avantor

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.

Supplier: Avantor

Avantor® Alltima HPLC columns are high quality phases designed for general purpose applications.

J.T.Baker® BAKERBOND®, Diol silica irregular 40 µm, 60 Å Prep LC sorbent packing media, 100 g

Supplier: VWR Chemicals

Non toxic dessicants, for adsorbing moisture from the atmosphere and gas streams, which contain iron salts as a colour indicator. The dry material has an intense orange colour and changes to a pale beige/white colour on adsorption of water.

Supplier: Avantor

Avantor® Partisil® was one of the first commercially available irregular silicas. A large surface area gives it a high loading capacity. Avantor® Partisil® ion-exchange materials are widely referenced and remain one of the most popular choices for analysts.

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.

Supplier: VWR Chemicals

Glassy, hard beads with an internal surface of approx. 800 m²/g. Because of its very large surface area, our beads exhibit a high adsorption capacity for water vapour. The beads can be reactivated without significantly reducing adsorption efficiency.
