Whatman™ GD/X sterile PES syringe filters

Sterile syringe filters with PES membrane and prefilter designed to support filtration of viscous, hard-to-filter samples with high solids content

The Whatman™ GD/X sterile, PES membrane syringe filters are designed to enable the filtration of viscous, hard-to-filter samples greater than 10 mL. Each unit contains a prefiltration stack of Whatman multigrade glass microfiber (GMF) and Glass fiber (GF/F) filters.  The combination of this pre-filtration stack and filter housing design enables you to filter highly particular loaded samples.
  • Reduces need for multiple syringe filters by processing three to seven times more sample volume than syringe filters without prefilters
  • Female luer lock for leak-free connections
  • High-efficiency Whatman GMF 150 and GF/F pre-filter media
  • Eliminates or greatly reduces the need to carry out separate prefiltration step for difficult-to-filter samples
