Whatman 6794-2502 25mm Dia, Puradisc, Non-Sterile, 0.2 micrometer Pore Size, Polyethersulfone (PES), 1000/pk (PN:6794-2502)

Whatman Puradisc™ syringe filters are designed for rapid filtration of liquid samples prior to laboratory analysis, including applications such as HPLC sample preparation, biological sample clarification, and removal of fine particulates from solutions. They are suitable for filtering sample volumes of up to about 100 mL.

A 0.2 µm pore size is commonly used to remove very fine particles and microorganisms from solutions. This level of filtration helps produce clearer samples and protects sensitive analytical instruments like chromatography systems from clogging or contamination.

This syringe filter uses a hydrophilic polyethersulfone (PES) membrane with a polypropylene housing, a combination known for chemical resistance, durability, and compatibility with many aqueous laboratory samples.

Puradisc filters are designed with standard female Luer-lock inlet and male Luer outlet connectors, allowing them to attach easily to most laboratory syringes and filtration setups for convenient sample processing.

PES syringe filters like the Whatman Puradisc series are widely used in pharmaceutical research, biotechnology labs, environmental testing, food analysis, and academic laboratories where fast, reliable filtration of aqueous samples is required before analytical testing.
