GD/X 25mm Syringe Filter, Glass Microfiber GF/D Filteration Medium, 2.7 um (150 pcs)
Whatman SKU: 6888-2527

Whatman GD/X Glass Fiber (GF) Syringe Filters, 2.7 µm, 25 mm, 150/Pk - 6888-2527

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Glass fiber sustains high dirt-loading capacity through depth filtration while holding structural integrity through conditioning and stays biologically inert across diverse chemistries. The PP housing prevents sample bypass under rated operating pressure while resisting degradation from routine sample matrices and keeps the fluid path low in extractable contamination. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Inorganic construction suits demanding sample-preparation chemistries
• Nominal depth retention with high dirt-loading capacity

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Stable across the full aqueous pH range in routine sample work
• Rigid polypropylene body holds its shape under manual filtration pressure
• Tough polypropylene body tolerates repeated handling at the bench

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data so column life and baseline stability stay predictable.
