Whatman Puradisc Glass Fiber (GF) Syringe Filters, 1 µm, 25 mm, 1000/Pk - 6792-2510

Whatman's filtration expertise, refined across a century-plus of disciplined manufacturing, has made its name synonymous with laboratory-grade quality worldwide. A syringe filter's small hold-up volume limits sample loss, a meaningful difference when working with a limited or precious sample. Naturally hydrophilic glass fiber wets rapidly with aqueous samples while staying biologically inert across diverse chemistries and sustains high dirt-loading capacity through depth filtration. Polypropylene construction resists chemical degradation from routine sample matrices while pressing snugly against the membrane during the pass and keeps sample purity intact through the filtration pass. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Technical Specifications

• Reduces bioburden and particulate load ahead of sterilizing-grade filtration
• Surface silanol groups attract water molecules for immediate aqueous wetting
• Extends filterable sample volume three to seven times versus unprotected media
• Biologically inert borosilicate fiber with broad chemical compatibility
• Inorganic construction suits demanding sample-preparation chemistries

Housing Specifications

• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Translucent housing wall allows visual confirmation of sample flow during filtration
• Optimized internal geometry minimizes backpressure in service
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on.
