Cellulose Acetate Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 10/Pk
GVS SKU: GF25BNPGA004AT01PF

GVS ABLUO Cellulose Acetate (CA) Syringe Filters, 0.7/0.45 µm, 25 mm, 10/Pk - GF25BNPGA004AT01PF

Every GVS syringe filter passes an integrity test confirming proper fit and weld, verification that the assembly is sealed against filter bypass. Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. Low-extractable cellulose acetate keeps filtrate clean ahead of analysis and screens out particulates exceeding that stated micron level. The MBS body forms a snug fit around the membrane to block bypass and copes reliably with routine aqueous sample matrices. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Selected specifically for PFAS-free sample preparation, the filter avoids the fluoropolymer components that can release per- and polyfluoroalkyl substances into an aqueous filtrate during analysis. Validated PFAS-free under independent laboratory testing, the filter adds no measurable per- and polyfluoroalkyl background to the trace analytes a sensitive method works to quantify. In environmental, wastewater, and food-safety PFAS testing, reported per- and polyfluoroalkyl concentrations reflect the sample itself rather than the filter used to prepare it for analysis.

Prefiltration

• Added glass fiber stage extends usable throughput by delaying membrane clogging
• Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
• Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane
• Glass fiber prefilter stage sustains flow through particle-laden, hard-to-filter samples

Membrane Characteristics

• Stable in aqueous saline, buffer, and protein solution matrices
• Naturally hydrophilic surface wets readily with aqueous samples
• Biologically nontoxic cellulose ester provides a clean filtration surface
• Cellulose ester backbone stable across aqueous pH range of 4 to 8
• Low extractable contribution keeps filtrate chemistry clean

Housing Characteristics

• Luer-compatible MBS housing connects directly to standard syringe tips for hand-pressure filtration
• Hard methacrylate surface resists scuffing through repeated handling
• Sub-wavelength core-shell rubber domains toughen the methacrylate matrix without introducing optical haze
• Handles aqueous acids, bases, and alcohols without issue during sample prep

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it.

• Vaccine and Plasma Processing - Staged 0.45 micron prefiltration reduces bioburden ahead of a final 0.2 micron sterilizing stage.
• Pharma Buffer Filtration - Low-extractable CA filters pharmaceutical-grade aqueous buffers ahead of formulation and biological assay applications.
• Food Safety Analysis - Hydrophilic CA clarifies aqueous food extracts and beverages ahead of pesticide residue, mycotoxin, and contaminant analysis.
• Saline Solution Prep - CA membrane filters saline and physiological buffer solutions, removing particulates for in vitro assays and formulation use.
• Microbial Limit Testing - CA membrane retains microorganisms from pharmaceutical solutions for USP microbial limits testing and bioburden assessment.
• Protein Recovery - Maximizes yield of target proteins by minimizing nonspecific binding, preserving valuable biological samples.
