PES Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
GVS SKU: FJ25BNPPS004AH01

GVS ABLUO Polyethersulfone (PES) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - FJ25BNPPS004AH01

Every GVS syringe filter passes an integrity test confirming proper fit and weld, verification that the assembly is sealed against filter bypass. Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. PES holds consistent absolute retention at the rated pore size and pairs fast flow with reduced protein adsorption. The PP housing sustains efficient flow on viscous samples while leaving no seam for sample to bypass the membrane and stays inert across common laboratory solvents. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Membrane Characteristics

• Sulfone backbone's hydrolytic stability tolerates repeated autoclave steam sterilization cycles
• Aromatic sulfone backbone underlies stability across the full pH range
• Absolute pore size rating holds consistent across every lot
• Ionic extractables from the membrane stay very low
• Compatibility spans both nucleic acid and protein-based filtration

Housing Characteristics

• Optimized internal geometry minimizes backpressure in service
• Maintains dimensional form and seal integrity through elevated-temperature sample preparation at its rated limit
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Impact-tolerant polypropylene body withstands routine bench handling without damage

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.

Hydrophilic

• Serum Filtration - Clarifies serum and plasma samples quickly while retaining critical proteins needed for accurate downstream analytical testing.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Life Science Prep - Speeds processing of viscous biological solutions, improving laboratory workflow efficiency during busy sample prep days.
