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

Whatman draws on Cytiva's broader manufacturing oversight while continuing a legacy of filtration work that touches laboratory research, environmental monitoring, and industrial processing alike. A sterilizing-grade syringe filter delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. Hydrophilic surface modification shields hydrophobic backbone from protein and blocks bacterial passage through its smallest rated openings. The polypropylene housing holds its seal true run after run and routes flow to minimize backpressure in service. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Autoclave sterilization cycles leave pore structure and flow performance intact
• Low extractables preserve a clean chromatographic baseline
• Filtration preserves mammalian cell viability, phenotype, and growth
• Mechanically durable membrane holds integrity under filtration pressure
• Hydrochloric, dilute nitric, and up to 90% sulfuric acid cause no attack

Housing Characteristics

• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Resists stress cracking from aqueous salt and buffer solutions
• Standardized luer connection geometry provides secure engagement with standard syringe tips

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.

• Microbiome Sampling - Concentrates waterborne microbial cells on a low-binding membrane ahead of DNA extraction and metagenomics sequencing.
• Protein Purification - Facilitates routine clarification of chromatography samples, preventing column fouling without binding target proteins.
• IC Guard Filtration - Removes particulates from aqueous samples before ion analysis, keeping detector cells free of fouling between injections.
• Spectroscopy Prep - Provides optical clarity and low background interference, ideal for UV-Vis and fluorescence sample preparation work.
• Forensic Toxicology Screening - Clarifies urine samples ahead of LC-MS drug screening, supporting reliable detection of abused drugs and metabolites.
• Mycotoxin Screening - Clarifies grain and food extracts ahead of HPLC analysis, supporting reliable detection of aflatoxins and other mycotoxins.
