Whatman GD/X disposable 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 unique prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfibre media, which allows you to filter difficult samples with less hand pressure. Compared to an unprotected membrane, GD/X syringe filters can process three to seven times more sample volume.

• Four filtration layers which substantially reduce blockage
• Three layers of glass microfibre (GMF) and a fourth layer to suit your application
• Increased flow rates even with high particulate samples
• Female luer lock inlet, male slip luer outlet
• Supplied in packs of 1500
