Glass Fiber Membrane Filters, GD-120, 10mm - 293mm

Advantec GD-120 Glass Fibre Filters – High-Capacity Prefilters for Analytical and Gravimetric Applications

Advantec GD-120 glass fibre filters are binderless, coarse-porosity filters designed as robust prefilters for particle-rich samples in analytical and gravimetric workflows. With a nominal retention of 0.9 µm and very high dirt loading capacity, these filters are ideal for protecting finer membranes and improving filtration efficiency in multi-stage setups.

Made from pure borosilicate microfibers, GD-120 filters combine high wet strength with fast flow rates, making them suitable for preclarification, liquid filtration, and particulate-laden environmental samples. Their durability and low extractables ensure clean and consistent performance in demanding laboratory applications.
