LabExact PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10040

A syringe filter dispenses filtrate directly into an autosampler vial, without the intermediate collection vessel a bulk vacuum filtration setup typically needs. Treated PTFE wets directly with aqueous samples while keeping solvent resistance and excludes particles larger than the declared micron limit. Pre-sterilized polypropylene construction is individually wrapped for direct use in sterile workflows while keeping sample purity intact through the filtration pass and maintains a low-dead-volume internal flow path. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Membrane Characteristics

• Insolubility in all known organic solvents avoids swelling and pore distortion
• Inert composition offers no nutrient source for microbial growth
• Chemical resistance spans the full pH 1 to 14 range
• Fully fluorinated carbon backbone resists ultraviolet and ozone degradation
• Stable across a wide operating temperature range for demanding methods

Housing Characteristics

• The seal formed against the membrane blocks bypass at rated operating pressure
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Polypropylene housing tolerates ethylene oxide gas sterilization cycles without softening or dimensional distortion
• Polypropylene housing retains its chemical integrity under vaporized hydrogen peroxide decontamination cycles used in aseptic processing isolators

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 so you can standardize one filter across most aqueous methods.

• Dissolution Testing - Stops the dissolution reaction and clarifies samples, with low API binding for accurate potency quantitation.
• Mobile Phase Prep - Extends column life by consistently removing particulates from organic HPLC mobile phases before every injection.
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in demanding atmospheric monitoring conditions.
• Cryogenic Fluids - Delivers consistent performance across extreme temperature ranges, filtering cryogenic liquids with dependable, reliable results.
• Agrochemical Formulation QC - Clarifies technical pesticide concentrates in organic solvent ahead of HPLC potency and impurity analysis.
• Extractables Testing - Clarifies packaging material organic solvent extracts ahead of LC-MS analysis, keeping background low for leachable detection.
