Filter diaphragm GD/X™ series

Our Whatman GD/X Syringe Filters are available in 13 and 25 mm diameter, sterile and non-sterile, with a range of membrane types and pore sizes. Whatman GD/X Syringe Filter 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 allow you to filter even the most difficult samples with less hand pressure. Whatman GD/X syringe filters can process three to seven times more sample volume than standard syringe filters.
