Pura Disc 13mm PTFE Syringe Filters, 0.1um, 100/Pk
Whatman SKU: 6784-1301

Whatman Puradisc PTFE Syringe Filters, 0.1 µm, 13 mm, 100/Pk - 6784-1301

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. Gas and vent service calls for a hydrophobic syringe filter rated to the same sterilizing-grade pore size as its liquid counterpart. Hydrophobic PTFE delivers sterilizing-grade gas and vent filtration at the rated pore size and suits gas, vent, and solvent-stream filtration. The polypropylene housing presses snugly against the membrane during the pass and sustains efficient flow on viscous samples. Downstream equipment and work areas stay protected from airborne bacterial contamination once the vent path runs through the membrane.

Technical Specifications

• Node-fibril microstructure resists compaction under sustained operating pressure
• Chemical resistance spans the full pH 1 to 14 range
• Low extractables keep the chromatographic background clean
• Absolute pore rating delivers reproducible retention across every protocol
• UL 94 V-0 rating confirms the highest self-extinguishing classification

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Translucent housing wall allows visual confirmation of sample flow during filtration
• Plasticizer-free polyolefin construction keeps the fluid path clean

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 before it moves on to your next process step.

• Mobile Phase Prep - Extends column life by consistently removing particulates from organic HPLC mobile phases before every injection.
• UV Spectroscopy - Clarifies solvent-based samples before UV/Vis analysis, removing scattering particulates for precise, reliable absorbance readings.
• Extractables Testing - Clarifies packaging material organic solvent extracts ahead of LC-MS analysis, keeping background low for leachable detection.
• Cosmetics Testing - Clarifies lotions and emulsions after alcohol pre-wetting, keeping products free of particulate contaminants.
• Dye and Pigment Analysis - Clarifies dye solutions in DMF, NMP, and other aggressive organics ahead of spectrophotometric color strength testing.
• Photoresist Filtration - Clarifies photoresist solutions in organic casting solvent ahead of spin-coating, reducing particulate defect risk.
