Glass Fiber/PES Syringe Filters, 0.7/0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 50/Pk
GVS SKU: GF25BNPGS002AL01

GVS ABLUO Polyethersulfone (PES) Syringe Filters, 0.7/0.22 µm, 25 mm, 50/Pk - GF25BNPGS002AL01

GVS syringe filters come out of the company's own United States facilities, built under the production controls its quality management system requires. 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. Low-binding PES achieves sterile-grade retention with high recovery and tolerates aliphatic alcohols, glycols, and aqueous buffers. The clear MBS housing keeps the filtrate visible during the pass while withstanding aqueous samples and buffers during routine prep work and takes hand pressure without cracking. 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

• 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
• Depth-loading glass fiber matrix captures particulate throughout its full thickness

Membrane Characteristics

• Aromatic sulfone backbone underlies stability across the full pH range
• Finest available pore ratings achieve aseptic-grade filtration performance
• Antibody and protein samples pass through PES with minimal adsorptive loss
• Compatibility spans both nucleic acid and protein-based filtration
• Chemical breadth spans alcohols, glycols, and aqueous buffers

Housing Characteristics

• Optically clear MBS housing keeps the sample visible end to end
• Hard methacrylate surface resists scuffing through repeated handling
• The housing keeps full contact with the membrane, so no sample passes around it
• Phthalate-free composition keeps a common LC-MS and GC-MS contaminant out of sample workflows

Unfiltered particulates shift your retention times and peak shapes from run to run. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.

Wettability

Hydrophilic

• Cell Culture - Reduces the risk of mycoplasma contamination in growth media, supporting healthier cell lines and more reliable experimental outcomes.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
• Media Preparation - Facilitates rapid sterilization of tissue culture additives, lowering contamination risk during sensitive laboratory work.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
