LabExact SKU: LE-IWT-ES10089

LabExact Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10089

Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Cellulose acetate admits water-based reagents immediately, with no surfactant step while binding BSA at 3.8 micrograms per square centimeter and holds a uniform pore structure for consistent results. Polyolefin construction sheds virtually no extractable material into the sample while staying inert across common laboratory solvents and leaves no seam for sample to bypass the membrane. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Stable in aqueous saline, buffer, and protein solution matrices
• Lot-to-lot uniformity in pore distribution produces consistent retention across batches
• Low extractable contribution keeps filtrate chemistry clean
• Native surface hydroxyl groups sustain a hydration layer ahead of protein contact
• Naturally hydrophilic surface wets readily with aqueous samples

Housing Characteristics

• Resists stress cracking from aqueous salt and buffer solutions
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Optimized internal geometry minimizes backpressure in service
• PP housing supplied sterile in individual packaging for immediate use in aseptic filtration without bench preparation

Hydrophilic

• LC-MS Sample Prep - CA's low-binding surface preserves small molecule and peptide analytes from adsorption during aqueous preparation for LC-MS runs.
• Serum Protein Analysis - Low-binding CA ensures serum proteins pass through without adsorption, preserving sample integrity for immunoassay panels.
• Food Safety Analysis - Hydrophilic CA clarifies aqueous food extracts and beverages ahead of pesticide residue, mycotoxin, and contaminant analysis.
• Biomarker Assay Prep - Low-binding CA prevents biomarker adsorption during sample prep, preserving analyte concentrations for immunoassay panels.
• Stability Testing Prep - Hydrophilic CA membrane clarifies stability samples without analyte loss, supporting accurate potency tracking over time.
• Pharma Buffer Filtration - Low-extractable CA filters pharmaceutical-grade aqueous buffers ahead of formulation and biological assay applications.
