Pura Disc 13mm PVDF Syringe Filters, 0.2um, 500 Pk
Whatman SKU: 6792-1302

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 500/Pk - 6792-1302

Whatman maintains in-house specialists who set and verify material specifications separately for its cellulose, glass-fiber, and polymer membrane chemistries, tailoring quality control to how each one behaves in use. 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. PVDF achieves sterile-grade retention at sub-micron pore sizes and suits HPLC sample preparation with immediate, reliable uptake. Low-extractable polypropylene keeps sample purity intact through the filtration pass while staying inert across common laboratory solvents and holds its seal true run after run. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Technical Specifications

• Hydrochloric, dilute nitric, and up to 90% sulfuric acid cause no attack
• Adsorptive loss of HPLC analytes stays immeasurably low
• Vapor-phase hydrogen peroxide decontamination cycles leave the membrane intact
• Resistance to hydrolytic degradation exceeds that of nylon membranes
• Chemical compatibility spans the full pH 1 to 14 range

Housing Specifications

• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.
• Medical-grade polypropylene with broad chemical compatibility
• Impact-tolerant polypropylene body withstands routine bench handling without damage

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification. Ask about Whatman's quality documentation to confirm your filtration step meets a recognized laboratory-science standard.
