Pura Disc 13mm GMF Syringe Filters, 0.45um, 500 Pk
Whatman SKU: 6818-1304

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 0.45 µm, 13 mm, 500/Pk - 6818-1304

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The borosilicate glass matrix tolerates repeated high-temperature pre-conditioning and captures particulates throughout its depth. Polypropylene construction resists chemical degradation from routine sample matrices and keeps the fluid path low in extractable contamination. 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
• Inorganic construction suits demanding sample-preparation chemistries
• 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

• Medical-grade polypropylene with broad chemical compatibility
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
