Grade B Glass Fiber Membrane Sheets, 8in x 10in

Sterlitech Grade B Glass Fibre Filters – High-Capacity Filters for Biochemical and Gas Filtration

Sterlitech Grade B glass fibre filters are binderless, fine-porosity filters designed for the collection of denatured biochemical polymers and solid particulate filtration from gases. With a nominal retention of 1.0 µm, Grade B offers a medium to fast flow rate and twice the thickness of Grade A, giving it higher loading capacity and improved durability in demanding filtration setups.

Constructed from pure borosilicate microglass fibres with no binders, these filters provide low extractables and thermal resistance up to 475°C, making them suitable for use as prefilters, gas filters, or in high-particulate biological workflows.

Key Features
