Description

General description

Sterile syringe filters with cellulose acetate membrane and prefilter designed to support filtration of viscous, hard-to-filter samples with high solids content. The Whatman GD/X sterile, cellulose acetate (CA) 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. Cytiva′s GD/X sterile syringe filter is suitable for preparing viscous, dense, or otherwise hard-to-filter samples prior to a variety of analytical methods.

Features and Benefits

• 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

Suitability

Suitable for filtering environmental and food analysis samples. Suitable for particulate laden sample preparation.
