LabExact Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10091

Because each syringe filter is dedicated to one sample, a failed or contaminated filtration stays isolated to its own analyst's run and leaves the next analyst's queue clear. Cellulose acetate delivers absolute particle retention at rated size while taking up aqueous buffers on contact and stays smooth with low extractable background. The polypropylene housing presses snugly against the membrane during the pass and ships pre-sterilized with individual packaging for aseptic filtration workflows. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Smooth membrane face with even pore distribution across the active filtration area
• No alcohol pre-wetting required before aqueous sample introduction
• Tolerates methanol and ethanol at typical laboratory working concentrations
• Biologically nontoxic cellulose ester provides a clean filtration surface
• Dilute samples retain their true, unadsorbed concentration through the membrane

Housing Characteristics

• Optimized internal geometry minimizes backpressure in service
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Stable across the full aqueous pH range in routine sample work
• Rigid polypropylene body maintains its geometry through routine filtration pressure

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.

• Fermentation Broth Prep - CA filters clarify fermentation broth samples, removing biomass ahead of glucose, ethanol, and metabolite measurement.
• Low-Volume Sample Prep - CA syringe filters process precious microliter samples with minimal hold-up volume, maximizing recovery of dilute analytes.
• Aqueous Sample Prep - CA membrane clarifies water-based samples quickly without pre-wetting, protecting downstream instruments from particle fouling.
• Biomarker Assay Prep - Low-binding CA prevents biomarker adsorption during sample prep, preserving analyte concentrations for immunoassay panels.
• Ophthalmic Formulation Prep - Low-extractable CA filters ophthalmic solutions ahead of quality testing and release without contributing contaminants.
• Cell Culture Filtration - CA membrane clarifies conditioned media and aqueous culture supplements without stripping nutrients or growth factors.
