LabExact PTFE Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10037

Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. The PTFE matrix handles concentrated acids and bases across demanding methods while accepting aqueous samples without alcohol pre-wetting and stays chemically inert against solvents, acids, and alkalis. The polypropylene housing holds its seal true run after run while staying inert across common laboratory solvents and routes flow to minimize backpressure in service. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Hydrofluoric acid resistance holds even in fully acid-digested samples
• Absolute pore rating delivers reproducible retention across every protocol
• Biological inertness resists enzymatic attack from proteases and lipases
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Insolubility in all known organic solvents avoids swelling and pore distortion

Housing Characteristics

• Optimized internal geometry minimizes backpressure in service
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion

Juggling several filter types for one routine clarification eats up your bench time. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it.

Hydrophilic

• Trace Metals Analysis - PTFE's low metal-extractable profile clarifies acid-digested samples for clean, low-background ICP-MS and ICP-OES results.
• Mobile Phase Prep - Extends column life by consistently removing particulates from organic HPLC mobile phases before every injection.
• Fuel Analysis Prep - Clarifies gasoline and other petroleum samples ahead of gas chromatography, protecting injector ports from residue buildup.
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, delivering pure filtrate quality consistently.
• Dye and Pigment Analysis - Clarifies dye solutions in DMF, NMP, and other aggressive organics ahead of spectrophotometric color strength testing.
• Battery Electrolyte Prep - Clarifies lithium-ion battery electrolyte in carbonate solvents ahead of GC-MS purity and impurity analysis.
