Tisch Scientific PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF14468

Tisch Scientific's product lineup extends from filtration membranes to devices and the consumable supplies laboratories use daily. Each hydrophobic vent-rated filter carries manufacturer bacterial retention testing built into the design, letting a vent line stay in continuous service without repeating that testing on site between uses. PTFE suits solvent and reagent filtration where other membranes fail and achieves sterile-grade retention in gas and vent service. The PP housing stays inert across common laboratory solvents and buffers in routine use while keeping sample purity intact through the filtration pass and routes flow to minimize backpressure in service. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.

Membrane Characteristics

• Validated against an aerosol Brevundimonas diminuta bacterial challenge
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Fully fluorinated carbon backbone resists ultraviolet and ozone degradation
• Ionic and metallic extractable levels stay very low
• Absolute pore rating delivers reproducible retention across every protocol

Housing Characteristics

• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Thermal-bonded construction keeps adhesives out of the fluid path
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion
• The seal formed against the membrane blocks bypass at rated operating pressure

Particulates left in your organic solvents and reagents carry downstream into the step that depends on a clean feed. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.

Hydrophobic

• Trace Metals Analysis - PTFE's low metal-extractable profile clarifies acid-digested samples for clean, low-background ICP-MS and ICP-OES results.
• Battery Electrolyte Prep - Clarifies lithium-ion battery electrolyte in carbonate solvents ahead of GC-MS purity and impurity analysis.
• Polymer GPC Prep - Clarifies polymer solutions in THF ahead of gel permeation chromatography, protecting columns from particulates.
• Cryogenic Fluids - Delivers consistent performance across extreme temperature ranges, filtering cryogenic liquids with dependable, reliable results.
• Extractables Testing - Clarifies packaging material organic solvent extracts ahead of LC-MS analysis, keeping background low for leachable detection.
• Pump Protection - Acts as a hydrophobic barrier that protects vacuum pumps from corrosive moisture and particulate damage.
