Pura Disc 13mm GF/D GMF Syringe Filters, 2.7 um, 100/Pk
Whatman SKU: 6823-1327

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 2.7 µm, 13 mm, 100/Pk - 6823-1327

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Glass fiber draws aqueous samples through without preconditioning while tolerating repeated high-temperature conditioning cycles and resists chemical attack across diverse solvents. Polypropylene construction holds extractable contribution low for sensitive analyses and maintains housing integrity through the filtration run. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.
