CA Syringe Filter, Nonsterile - 0.22µm, 13mm, Hydrophilic, Luer-Lok®, 100/Pk
LabExact SKU: LE-IWT-ES10081

LabExact Cellulose Acetate (CA) Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10081

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 cellulose acetate matrix stays stable across pH 4 to 8 while staying smooth with low extractable background and relies on hydroxyl chemistry alone, no coating needed. The PP housing stays inert across common laboratory solvents and buffers in routine use while preserving sample chemistry across the flow path and routes flow to minimize backpressure in service. 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

• Stable in aqueous saline, buffer, and protein solution matrices
• Biologically nontoxic cellulose ester provides a clean filtration surface
• Absolute-rated pores ensure the same particle cutoff every run
• Lot-to-lot uniformity in pore distribution produces consistent retention across batches
• Native surface hydroxyl groups sustain a hydration layer ahead of protein contact

Housing Characteristics

• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Translucent housing wall allows visual confirmation of sample flow during filtration
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.

• Serum Protein Analysis - Low-binding CA ensures serum proteins pass through without adsorption, preserving sample integrity for immunoassay panels.
• PCR Sample Prep - CA's very low non-specific binding ensures nucleic acids and buffer components pass through cleanly ahead of PCR amplification.
• Protein Recovery - Maximizes yield of target proteins by minimizing nonspecific binding, preserving valuable biological samples.
• Biomarker Assay Prep - Low-binding CA prevents biomarker adsorption during sample prep, preserving analyte concentrations for immunoassay panels.
• Cell Culture Filtration - CA membrane clarifies conditioned media and aqueous culture supplements without stripping nutrients or growth factors.
• Low-Volume Sample Prep - CA syringe filters process precious microliter samples with minimal hold-up volume, maximizing recovery of dilute analytes.
