LabExact PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10199

Because each syringe filter is dedicated to one sample, a failed or contaminated filtration stays isolated to its own analyst's run and leaves the next analyst's queue clear. PTFE filters aggressive organic solvents without swelling or breakdown while maintaining absolute retention consistency at every rated size and suits gas, vent, and solvent-stream filtration. The PP housing stays inert across common laboratory solvents and buffers in routine use while pressing snugly against the membrane during the pass and ships pre-sterilized with individual packaging for aseptic filtration workflows. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Membrane Characteristics

• Stable across a wide operating temperature range for demanding methods
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Low extractables keep the chromatographic background clean
• Chemical resistance spans the full pH 1 to 14 range
• Membrane integrity holds across repeated autoclave sterilization cycles at 121°C to 134°C

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure
• Translucent housing wall allows visual confirmation of sample flow during filtration

A filter that softens or swells in your solvent fails you mid-run, batch after batch. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.

Hydrophobic

• Battery Electrolyte Prep - Clarifies lithium-ion battery electrolyte in carbonate solvents ahead of GC-MS purity and impurity analysis.
• Pump Protection - Acts as a hydrophobic barrier that protects vacuum pumps from corrosive moisture and particulate damage.
• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids for compatibility with harsh synthetic reaction mixtures.
• Dissolution Testing - Stops the dissolution reaction and clarifies samples, with low API binding for accurate potency quantitation.
• Spirits Congener Analysis - Clarifies distilled spirits samples ahead of GC analysis, protecting columns from residue during congener profiling.
• Dye and Pigment Analysis - Clarifies dye solutions in DMF, NMP, and other aggressive organics ahead of spectrophotometric color strength testing.
