LabExact Cellulose Acetate (CA) Syringe Filters, 1 µm, 25 mm, 100/Pk - LE-IWT-ES-10752

A syringe filter dispenses filtrate directly into an autosampler vial, without the intermediate collection vessel a bulk vacuum filtration setup typically needs. Cellulose acetate suits aqueous solutions, buffers, and alcohols in routine use while staying smooth with low extractable background and shield the polymer chains from direct protein adsorption. The PP housing sustains efficient flow on viscous samples and preserves sample chemistry across the flow path. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Biologically nontoxic cellulose ester provides a clean filtration surface
• BSA adsorption near 3.8 micrograms per square centimeter across the membrane
• Native surface hydroxyl groups sustain a hydration layer ahead of protein contact
• Retains particles at the membrane surface instead of throughout its thickness
• Naturally hydrophilic surface wets readily with aqueous samples

Housing Characteristics

• Optimized internal geometry minimizes backpressure in service
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion
• 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

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.

Wettability

Hydrophilic

• Biomarker Assay Prep - Low-binding CA prevents biomarker adsorption during sample prep, preserving analyte concentrations for immunoassay panels.
• Aqueous Sample Prep - CA membrane clarifies water-based samples quickly without pre-wetting, protecting downstream instruments from particle fouling.
• Stability Testing Prep - Hydrophilic CA membrane clarifies stability samples without analyte loss, supporting accurate potency tracking over time.
• LC-MS Sample Prep - CA's low-binding surface preserves small molecule and peptide analytes from adsorption during aqueous preparation for LC-MS runs.
• Urinalysis Prep - CA clarifies urine samples by removing particulates ahead of automated urinalysis without altering biochemical composition.
• Food Safety Analysis - Hydrophilic CA clarifies aqueous food extracts and beverages ahead of pesticide residue, mycotoxin, and contaminant analysis.
