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's brand recognition and documented performance history support specification in standardized analytical methods. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Glass fiber withstands high-temperature pre-conditioning up to 500°C while offering broad chemical compatibility and sustains high dirt-loading capacity through depth filtration. The PP housing keeps the fluid path low in extractable contamination and prevents sample bypass under rated operating pressure. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
