Whatman™ GD/X Syringe Filters

Whatman™ GD/X™ syringe filters are the ideal choice for the preparation of hard-to-filter samples. The syringe filters have a pigment-free polypropylene housing to eliminate sample contamination and contain a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media, which allows you 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 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. Below the prefilter stack is the final membrane. This provides exceptional loading capacity with fast flow rates and avoids the build-up of back pressure often experienced through blocking of an unprotected membrane.

Offered as13mm and 25mm diameter syringe filters for samples up to 10mL and larger than 10mL, respectively. Available sterile or nonsterile.
