Pura Disc 25mm GMF Syringe Filters, 0.7um, 1000 Pk
Whatman SKU: 6787-2520

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 0.7 µm, 25 mm, 1000/Pk - 6787-2520

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Glass microfiber holds structural integrity through high-temperature conditioning cycles while sustaining high dirt-loading capacity and wets rapidly with aqueous samples. Polypropylene construction maintains housing integrity through the filtration run while staying inert across common laboratory solvents and holds extractables low for sensitive analyses. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
