Pura Disc 25mm GD2 GMF Syringe Filters, 2.0um, 100/Pk
Whatman SKU: 6783-2520

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 2 µm, 25 mm, 100/Pk - 6783-2520

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Inorganic glass fiber offers broad chemical compatibility for demanding samples and tolerates repeated high-temperature conditioning cycles. The PP housing prevents sample bypass under rated operating pressure while resisting aqueous acids, bases, and alcohols and sustains efficient flow on viscous samples. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

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
• Nominal depth retention with high dirt-loading capacity
• Naturally hydrophilic surface wets rapidly with aqueous samples

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
