LabExact PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10041

A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. The PTFE matrix handles concentrated acids and bases across demanding methods and withstands aggressive organics that degrade other media. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while maintaining a low-dead-volume internal flow path and leaves no seam for sample to bypass the membrane. Where bacterial contamination must stay out of the sample, manufacturer-tested retention keeps the instrument and downstream assay protected without a housing to maintain or clean.

Membrane Characteristics

• Inert composition offers no nutrient source for microbial growth
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Aqueous buffers and HPLC mobile phases wet the hydrophilic surface instantly
• 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
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Medical-grade polypropylene with broad chemical compatibility

Juggling several filter types for one routine clarification eats up your bench time. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.

Hydrophilic

• Dye and Pigment Analysis - Clarifies dye solutions in DMF, NMP, and other aggressive organics ahead of spectrophotometric color strength testing.
• Spirits Congener Analysis - Clarifies distilled spirits samples ahead of GC analysis, protecting columns from residue during congener profiling.
• Extractables Testing - Clarifies packaging material organic solvent extracts ahead of LC-MS analysis, keeping background low for leachable detection.
• Photoresist Filtration - Clarifies photoresist solutions in organic casting solvent ahead of spin-coating, reducing particulate defect risk.
• Battery Electrolyte Prep - Clarifies lithium-ion battery electrolyte in carbonate solvents ahead of GC-MS purity and impurity analysis.
• Toxicology Screening - Clarifies protein-precipitated serum, plasma, and urine extracts ahead of LC-MS or GC-MS drug screening analysis.
