GVS ABLUO Cellulose Acetate (CA) Syringe Filters, 0.7/0.45 µm, 25 mm, 50/Pk - GF25BNPGA004AL01
Class 100,000 cleanroom conditions govern GVS's syringe filter and membrane production, held to the specifications its quality management system defines. 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. The cellulose acetate matrix stays stable across pH 4 to 8 while admitting water-based reagents immediately, with no surfactant step and maintains a particle cutoff at that rating. The polypropylene housing routes flow to minimize backpressure in service while standing firm against aqueous acids, bases, and alcohols during regular handling 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.
Prefiltration
- Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane
- Added glass fiber stage extends usable throughput by delaying membrane clogging
- High dirt-holding capacity suits very turbid, high-solids sample loads
- Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
Membrane Characteristics
- Native surface hydroxyl groups sustain a hydration layer ahead of protein contact
- Stable in aqueous saline, buffer, and protein solution matrices
- Dilute samples retain their true, unadsorbed concentration through the membrane
- Cellulose acetate's open pore structure supports high flow rates at low operating pressure
- Lot-to-lot uniformity in pore distribution produces consistent retention across batches
Housing Characteristics
- Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
- Inert polyolefin wall contributes minimal sample adsorption to the filtrate
- Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
- 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.
