Grade D Borosilicate Glass Microfiber Sheets, 8in x 10in

Sterlitech Grade D Glass Fibre Filters – High-Volume Prefilters for Repetitive Laboratory Filtration

Sterlitech Grade D glass fibre filters are binderless, coarse-porosity filters designed for high-throughput and repetitive filtration tasks. With a nominal particle retention of 2.7 µm and a fast flow rate, they are particularly well suited as general-purpose prefilters, helping to extend the life of primary membrane filters in multi-stage filtration systems.

Constructed from pure borosilicate glass microfibers, these filters offer low extractables, high thermal stability, and reliable mechanical performance, even under continuous use.
