Pura Disc 13mm PVDF Syringe Filters, 0.2um, 2000 Pk
Whatman SKU: 6765-1302

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 2000/Pk - 6765-1302

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Hydrophilic PVDF suits HPLC sample preparation and aqueous clarification and preserves dilute proteins and analytes in the filtrate. The polypropylene housing contributes minimal extractables to the filtrate while routing flow to minimize backpressure in service and resists degradation from routine sample matrices. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Low extractables preserve a clean chromatographic baseline
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Mechanically durable membrane holds integrity under filtration pressure
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep

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.
