Whatman Syringe Filter PVDF Filter Media 0.2 um 150 Filters

Whatman 6872-1302 Puradisc Syringe Filter – 13 mm, 0.2 µm PVDF

The Whatman 6872-1302 is a high-performance Puradisc syringe filter designed for the rapid and efficient filtration of sensitive biological and analytical samples. Featuring a 0.2 micron PVDF (polyvinylidene fluoride) membrane, this filter offers a unique combination of high flow rates and extremely low protein binding, making it an ideal choice for applications where maximum protein recovery is essential. The 13 mm diameter is specifically engineered for processing small sample volumes (up to 10 mL), minimizing dead volume and ensuring high yields of precious samples. Encapsulated in a medical-grade, pigment-free polypropylene housing, these filters ensure high chemical purity and broad compatibility with both aqueous and mild organic solvents.

Technical Performance and Design

• Extremely Low Protein Binding: The PVDF membrane is specifically selected for its minimal interaction with proteins and other biomolecules, ensuring that your analytes remain in the filtrate rather than being lost to the filter matrix.

• 0.2 µm Fine Retention: Provides absolute-rated filtration to remove fine particulates and microbial contaminants, serving as an excellent pre-filtration step for HPLC, UHPLC, and mass spectrometry (LC-MS).

• Low Hold-up Volume: The 13 mm Puradisc design features an optimized internal flow path to reduce fluid retention, making it superior to larger filters when working with limited sample quantities.

• Pigment-Free Polypropylene: The housing is manufactured without dyes or pigments, eliminating the risk of leachables or extractables interfering with sensitive analytical results.
