LabExact Nylon Syringe Filters, 0.22 µm, 30 mm, 100/Pk - LE-IWT-ES10304

Sterilizing-grade syringe filters deliver sterile-grade retention as a single-use format, eliminating the autoclaving and cleaning cycle a reusable sterile filtration setup would require. The nylon membrane delivers bacterial retention at the rated pore size while withstanding elevated differential pressures and moves aqueous buffers through without pre-wetting. The polypropylene housing preserves sample chemistry across the flow path and sustains efficient flow on viscous samples. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

Membrane Characteristics

• Common ketone solvents, including acetone, methyl ethyl ketone, and methyl isobutyl ketone, cause no attack
• Gamma-sterilized in sealed packaging for immediate aseptic use
• Filtration clarifies HPLC mobile phase buffers of particulates
• Tortuous, reticulated pore structure yields more usable filtration area than capillary-pore membranes
• Ester- and alcohol-resistant across common laboratory sample preparations

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Withstands ethylene oxide gas sterilization without embrittlement or structural damage
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• The seal formed against the membrane blocks bypass at rated operating pressure

A column clogging mid-run from unfiltered sample can cost you the rest of your analytical day. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.

Hydrophilic

• Fermentation Monitoring - Clarifies samples from microbial fermentation for rapid analyte measurement of glucose, ethanol, and metabolite levels.
• Solvent Filtering - Supports clarification of ester-based and alcohol solvents with precision during routine laboratory sample processing.
• IC Column Protection - Clarifies aqueous samples ahead of anion and cation analysis, guarding ion-exchange columns against particulate fouling.
• Amino Acid Profiling - Clarifies aqueous sample digests for HPLC and LC-MS amino acid analysis in food, nutrition, and fermentation monitoring.
• Column Protection - Extends the life of analytical columns by reliably removing micro-particulates from aqueous mobile phases in HPLC.
• GC Sample Prep - Clarifies aqueous and organic extracts ahead of gas chromatography injection, protecting inlets from particulate fouling.
