Pura Disc 13mm PTFE Syringe Filters, 0.2um, 500 Pk
Whatman SKU: 6783-1302

Whatman Puradisc PTFE Syringe Filters, 0.2 µm, 13 mm, 500/Pk - 6783-1302

Whatman verifies performance ratings at the lot level using process controls that stay uniform across its entire filtration lineup. Gas and vent service calls for a hydrophobic syringe filter rated to the same sterilizing-grade pore size as its liquid counterpart. The hydrophobic PTFE membrane suits gas, vent, and solvent-stream filtration while providing bacterial retention in gas and vent streams and filters aggressive organic solvents without breakdown. Polypropylene construction maintains a low-dead-volume internal flow path while keeping sample purity intact through the filtration pass and maintains structural integrity through elevated-temperature sample preparation. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.

Technical Specifications

• Chemical resistance spans the full pH 1 to 14 range
• Stable across a wide operating temperature range for demanding methods
• Membrane integrity holds across repeated autoclave sterilization cycles at 121°C to 134°C
• Inert composition offers no nutrient source for microbial growth
• Minimal moisture absorption pairs with a low tare mass

Housing Specifications

• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Medical-grade polypropylene with broad chemical compatibility
• The seal formed against the membrane blocks bypass at rated operating pressure

Removing particulates from organic solvents and reagents before they move downstream keeps contamination out of your results. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run.
