Whatman GD/X Syringe Filters Polyethersulfone 0.2µm 25mm Pack of 150

Whatman GD/X Syringe Filters Polyethersulfone 0.2µm 25mm Pack of 150

Whatman GD/X range is specifically designed for high particulate loaded samples. Constructed of a pigment-free polypropylene housing with a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media, these filters eliminate sample contamination and allow you to filter even the most difficult samples with less hand pressure. GD/X syringe filters can process three to seven times more sample volume than standard syringe filters.

GMF 150 and GF/F are produced from 100% borosilicate glass microfiber. The innovative, graded density GMF 150 medium has a coarse top layer meshed with a fine bottom layer that retains particles to 1.0µm. A GF/F filter then retains particles down to 0.7µm. The prefilter stack ends with a final membrane.

Whatman GD/X filter construction facilitates exceptional loading capacity with fast flow rates. This prevents the build up of back pressure typically caused by the blocking of an unprotected membrane.

• 13 or 25mm diameter syringe filters
