Glass Fiber/PVDF Syringe Filters, 0.7/0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 50/Pk
GVS SKU: GF25BNPGV002AL01

GVS ABLUO PVDF Syringe Filters, 0.7/0.22 µm, 25 mm, 50/Pk - GF25BNPGV002AL01

Every GVS syringe filter passes an integrity test confirming proper fit and weld, verification that the assembly is sealed against filter bypass. Sterilizing-grade syringe filters deliver sterile-grade retention as a single-use format, eliminating the autoclaving and cleaning cycle a reusable sterile filtration setup would require. A hydration layer at the pore surface keeps HPLC analytes from adhering while stopping bacteria at its finest sub-micron ratings and resists HPLC mobile phases, alcohols, and mild hydrocarbons. Polypropylene construction maintains a low-dead-volume internal flow path while standing firm against aqueous acids, bases, and alcohols during regular handling and holds its seal true run after run. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Prefiltration

• Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane
• 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

Membrane Characteristics

• Low extractables preserve a clean chromatographic baseline
• Filtration preserves mammalian cell viability, phenotype, and growth
• Autoclave sterilization cycles leave pore structure and flow performance intact
• Resistance to hydrolytic degradation exceeds that of nylon membranes
• Gamma irradiation sterilization causes no chain scission unlike polypropylene membranes

Housing Characteristics

• Thermal-bonded construction keeps adhesives out of the fluid path
• Maintains dimensional form and seal integrity through elevated-temperature sample preparation at its rated limit
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

An unfiltered buffer can foul your instrument and interrupt a run mid-sequence. Upstream buffer clarification keeps your run from stalling on particulates that slipped through before they reach the column inlet or detector.

• QuEChERS Extract Prep - Removes co-extracted waxes and pigments from QuEChERS extracts, protecting GC-MS and LC-MS systems during pesticide testing.
• Protein Purification - Facilitates routine clarification of chromatography samples, preventing column fouling without binding target proteins.
• Mycotoxin Screening - Clarifies grain and food extracts ahead of HPLC analysis, supporting reliable detection of aflatoxins and other mycotoxins.
• Microbiome Sampling - Concentrates waterborne microbial cells on a low-binding membrane ahead of DNA extraction and metagenomics sequencing.
• Trace Analysis - Prevents non-specific binding in trace analysis, keeping low-concentration analytes in solution for reliable detection.
• Immunochemistry Research - Delivers exceptional chemical resistance for mild organic mixtures used in sensitive immunochemical research applications.
