Whatman GD/X disposable syringe filters are for the preparation of hard-to-filter samples. The syringe filters have a pigment-free polypropylene housing to eliminate sample contamination and contain a pre-filtration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media, which allows users to filter even the most difficult samples with less hand pressure. Compared to an unprotected membrane, GD/X syringe filters can process three to seven times more sample volume. GMF 150 (graded density) and GF/F are produced from 100% borosilicate glass microfiber. The unique, graded density GMF 150 medium has a coarse top layer meshed with a fine layer beneath that retains particles to 1.0 µm. A GF/F filter then retains particles down to 0.7 µm. The prefilter stack is below the final membrane. This provides exceptionally good loading capacity with fast flow rates and avoids the build-up of back pressure often experienced through “blocking” of an unprotected membrane.
