Pura Disc 25mm GD1 GMF Syringe Filters, 1.0um, 100/Pk
Whatman SKU: 6783-2510

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 1 µm, 25 mm, 100/Pk - 6783-2510

Whatman standardizes its manufacturing platform to the point that consistency and thorough lot-level records come as a default, exactly what analytical laboratory work demands. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Glass fiber stays biologically inert across a broad range of chemistries while sustaining high dirt-loading capacity and wets rapidly with aqueous samples. The polypropylene housing holds its seal true run after run while sustaining efficient flow on viscous samples and stands firm against aqueous acids, bases, and alcohols during regular handling. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Technical Specifications

• Surface silanol groups attract water molecules for immediate aqueous wetting
• Autoclave steam sterilization at 121°C leaves structural integrity intact
• Biologically inert borosilicate fiber with broad chemical compatibility
• Reduces bioburden and particulate load ahead of sterilizing-grade filtration
• Inorganic construction suits demanding sample-preparation chemistries

Housing Specifications

• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.
• Stable across the full aqueous pH range in routine sample work
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure.
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
