LabExact Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10082

A syringe filter dispenses filtrate directly into an autosampler vial, without the intermediate collection vessel a bulk vacuum filtration setup typically needs. Cellulose acetate binds BSA at 3.8 micrograms per square centimeter and handles water-based samples and low-alcohol solutions. Low-extractable polypropylene keeps sample purity intact through the filtration pass while leaving no seam for sample to bypass the membrane and maintains a low-dead-volume internal flow path. Where analytical results depend on clean samples, the preparation step stays consistent from sample to sample through a pre-tested syringe filter.

Membrane Characteristics

• Lot-to-lot uniformity in pore distribution produces consistent retention across batches
• BSA adsorption near 3.8 micrograms per square centimeter across the membrane
• Minimal non-specific adsorption of analytes at the membrane surface
• Native surface hydroxyl groups sustain a hydration layer ahead of protein contact
• No alcohol pre-wetting required before aqueous sample introduction

Housing Characteristics

• Resists stress cracking from aqueous salt and buffer solutions
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• Saline Solution Prep - CA membrane filters saline and physiological buffer solutions, removing particulates for in vitro assays and formulation use.
• PCR Sample Prep - CA's very low non-specific binding ensures nucleic acids and buffer components pass through cleanly ahead of PCR amplification.
• TOC Sample Prep - Hydrophilic CA removes particles from water samples with minimal carbon contribution, protecting total organic carbon measurement.
• Ophthalmic Formulation Prep - Low-extractable CA filters ophthalmic solutions ahead of quality testing and release without contributing contaminants.
• Urinalysis Prep - CA clarifies urine samples by removing particulates ahead of automated urinalysis without altering biochemical composition.
• Alcohol Compatibility - Handles low molecular weight alcohols reliably, supporting specialized chemical clarification tasks in the laboratory.
