LabExact PTFE Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10042

Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. The treated PTFE membrane combines aqueous wetting with broad solvent resistance while suiting solvent filtration where other membranes fail and reaches the same absolute retention on every run. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane and ships pre-sterilized with individual packaging for aseptic filtration workflows. Where analytical results depend on clean samples, the preparation step stays consistent from sample to sample through a pre-tested syringe filter.

Membrane Characteristics

• Absolute pore rating delivers reproducible retention across every protocol
• Membrane integrity holds across repeated autoclave sterilization cycles at 121°C to 134°C
• Strong oxidizing agents like nascent chlorine and concentrated sodium hydroxide cause no attack
• Insolubility in all known organic solvents avoids swelling and pore distortion
• UL 94 V-0 rating confirms the highest self-extinguishing classification

Housing Characteristics

• Polypropylene housing tolerates ethylene oxide gas sterilization cycles without softening or dimensional distortion
• Optimized internal geometry minimizes backpressure in service
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• Impact-tolerant polypropylene body withstands routine bench handling without damage

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.

• Photoresist Filtration - Clarifies photoresist solutions in organic casting solvent ahead of spin-coating, reducing particulate defect risk.
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, delivering pure filtrate quality consistently.
• Polymer GPC Prep - Clarifies polymer solutions in THF ahead of gel permeation chromatography, protecting columns from particulates.
• Spirits Congener Analysis - Clarifies distilled spirits samples ahead of GC analysis, protecting columns from residue during congener profiling.
• Battery Electrolyte Prep - Clarifies lithium-ion battery electrolyte in carbonate solvents ahead of GC-MS purity and impurity analysis.
• Trace Metals Analysis - PTFE's low metal-extractable profile clarifies acid-digested samples for clean, low-background ICP-MS and ICP-OES results.
