GD/X 13mm Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6872-1304

Whatman GD/X PVDF Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6872-1304

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. PVDF resists HPLC mobile phases, alcohols, and mild hydrocarbons while holding consistent absolute retention at the rated pore size and suits HPLC sample preparation and aqueous clarification. The PP housing stays inert across common laboratory solvents and buffers while maintaining a low-dead-volume internal flow path and contributes minimal extractables to the filtrate. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Mechanically durable membrane holds integrity under filtration pressure
• Low extractables preserve a clean chromatographic baseline
• Absolute pore size rating gives consistent results across protocols
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons

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
• Optimized internal geometry minimizes backpressure in service

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.

• Western Blotting - Optimized for use in preparing samples for downstream blotting techniques where purity is paramount
• Protein Analysis - Ultra-low protein binding ensures that your expensive protein samples are not lost to the filter matrix
• HPLC Sample Prep - PVDF provides a great balance of chemical compatibility and low background noise for sensitive UV detection
• Clarification of Biologicals - Perfect for removing particulates from biological fluids without removing the target biomolecules
• Particulate Removal - Designed for removing particulates, this filter aids in protecting analytical instruments across diverse sample types
• Environmental Monitoring - Ideal for removing particulates in water and wastewater analysis to ensure regulatory compliance
