Pura Disc 13mm GF/B GMF Syringe Filters, 1.0um, 100/Pk
Whatman SKU: 6821-1310

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 1 µm, 13 mm, 100/Pk - 6821-1310

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. Many syringe filters ship with lot-specific quality documentation, giving analysts traceability that an ad hoc bulk filtration setup typically lacks. The borosilicate glass matrix resists chemical attack across diverse solvents while delivering nominal retention as a depth medium and accepts water-based samples on contact. Polyolefin construction sheds virtually no extractable material into the sample while staying inert across common laboratory solvents and holds its seal true run after run. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Technical Specifications

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

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Dilute aqueous acids, bases, and alcohols used in sample prep do not degrade the polypropylene housing
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Translucent housing wall allows visual confirmation of sample flow during filtration

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on.
