Pura Disc 13mm PVDF Syringe Filters, 0.2um, 50 Pk
Whatman SKU: 6777-1302

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 50/Pk - 6777-1302

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Hydrophilic PVDF minimizes protein binding for high HPLC sample recovery and wets aqueous and HPLC samples on contact. The polypropylene housing contributes minimal extractables to the filtrate and maintains a low-dead-volume internal flow path. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Sterilizing-grade retention at sub-micron pore sizes
• Low extractables preserve a clean chromatographic baseline
• Absolute pore size rating gives consistent results across protocols
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Mechanically durable membrane holds integrity under filtration pressure

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.

• HPLC Sample Prep - PVDF provides a great balance of chemical compatibility and low background noise for sensitive UV detection
• Protein Analysis - Ultra-low protein binding ensures that your expensive protein samples are not lost to the filter matrix
• Western Blotting - Optimized for use in preparing samples for downstream blotting techniques where purity is paramount
• Clarification of Biologicals - Perfect for removing particulates from biological fluids without removing the target biomolecules
• Biological Fluid Analysis - Protects sensitive downstream instruments from filtering contaminants that can cause system failure
• Quality Control Testing - Optimized for delivering reproducible results by filtering contaminants in standard pharmaceutical protocols
