Whatman Puradisc PTFE Syringe Filters, 0.2 µm, 13 mm, 100/Pk - 6784-1302

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 single-use hydrophobic vent filter reaches sterilizing-grade retention on a vent line without the autoclave cycle or in-line housing a reusable gas filtration setup would require. Hydrophobic PTFE delivers sterilizing-grade gas and vent filtration at the rated pore size while repelling water and passing gases and solvents freely and suits solvent filtration where other membranes fail. The PP housing sustains full structural integrity during elevated-temperature filtration operations while shedding virtually no extractable material into the sample and holds its seal true run after run. No separate sterilization cycle is needed when the gas path already runs through a validated sterile-grade membrane.

Technical Specifications

• High membrane porosity, 70 to 80 percent void volume, delivers high flow at low pressure
• Hydrofluoric acid resistance holds even in fully acid-digested samples
• Absolute pore rating delivers reproducible retention across every protocol
• Inert composition offers no nutrient source for microbial growth
• Solvent tolerance includes full-strength tetrahydrofuran and chlorinated solvents such as dichloromethane

Housing Specifications

• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Stable across the full aqueous pH range in routine sample work
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.
• Minimal extractable release from the housing supports sensitive analytical work downstream

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through further processing.
