Cellulose Acetate Syringe Filters, 0.7/0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 50/Pk
GVS SKU: GF25BNPGA002AL01

GVS ABLUO Cellulose Acetate (CA) Syringe Filters, 0.7/0.22 µm, 25 mm, 50/Pk - GF25BNPGA002AL01

GVS casts its own microporous membranes and assembles them into finished syringe filters under one roof, rather than sourcing either component externally. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. The cellulose acetate matrix stays stable across pH 4 to 8 while maintaining a hydrated barrier ahead of any protein contact and keeps sterilizing-level assurance steady across its narrowest ratings. Polypropylene construction maintains a low-dead-volume internal flow path and stands firm against aqueous acids, bases, and alcohols during regular handling. Where bacterial contamination must stay out of the sample, manufacturer-tested retention keeps the instrument and downstream assay protected without a housing to maintain or clean.

Prefiltration

• High dirt-holding capacity suits very turbid, high-solids sample loads
• Added glass fiber stage extends usable throughput by delaying membrane clogging
• Glass fiber prefilter stage sustains flow through particle-laden, hard-to-filter samples
• Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane

Membrane Characteristics

• BSA adsorption near 3.8 micrograms per square centimeter across the membrane
• Smooth membrane face with even pore distribution across the active filtration area
• Lot-to-lot uniformity in pore distribution produces consistent retention across batches
• Cellulose ester backbone stable across aqueous pH range of 4 to 8
• Absolute-rated pores ensure the same particle cutoff every run

Housing Characteristics

• Minimal extractable release from the housing supports sensitive analytical work downstream
• Optimized internal geometry minimizes backpressure in service
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation

Particulates that reach your column with the sample foul the frits and shorten its life. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.

• DNA Extraction Prep - CA's low-binding surface passes aqueous DNA extracts cleanly ahead of PCR, gel electrophoresis, and sequencing preparation.
• HPLC Sample Prep - Clarifies injection samples and mobile phases ahead of LC analysis, protecting columns from particulate fouling.
• PCR Sample Prep - CA's very low non-specific binding ensures nucleic acids and buffer components pass through cleanly ahead of PCR amplification.
• Low-Volume Sample Prep - CA syringe filters process precious microliter samples with minimal hold-up volume, maximizing recovery of dilute analytes.
• Clinical Chemistry Prep - Clarifies turbid or lipemic serum and plasma samples ahead of loading onto automated clinical chemistry analyzers.
• Urinalysis Prep - CA clarifies urine samples by removing particulates ahead of automated urinalysis without altering biochemical composition.
