Pura Disc 13mm GF/C GMF Syringe Filters, 1.2um, 100/Pk
Whatman SKU: 6822-1312

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 1.2 µm, 13 mm, 100/Pk - 6822-1312

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The glass microfiber matrix accepts water-based samples on contact while staying biologically inert across diverse chemistries and captures particulates throughout its depth. Polypropylene construction holds extractable contribution low for sensitive analyses and holds a reliable seal against the membrane edge. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Nominal depth retention with high dirt-loading capacity
• Inorganic construction suits demanding sample-preparation chemistries
• Biologically inert borosilicate fiber with broad chemical compatibility
• Withstands high-temperature pre-conditioning up to 500°C
• Naturally hydrophilic surface wets rapidly with aqueous samples

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.
