Pura Disc 25mm GF/F GMF Syringe Filters, 0.7um, 50 Pk
Whatman SKU: 6825-2517

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 0.7 µm, 25 mm, 50/Pk - 6825-2517

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The borosilicate glass matrix resists chemical attack across diverse solvents and sustains high dirt-loading capacity through depth filtration. Polypropylene construction maintains a low-dead-volume internal flow path while holding a reliable seal against the membrane edge and resists degradation from routine sample matrices. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

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

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.
