GVS ABLUO PTFE Syringe Filters, 0.45 µm, 25 mm, 500/Pk - FJ25BNPPH004AD01

GVS syringe filters come out of the company's own United States facilities, built under the production controls its quality management system requires. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The PTFE membrane clarifies solvent streams at the rated pore size while staying chemically inert against solvents, acids, and alkalis in service and combines aqueous wetting with broad solvent resistance. The PP housing stays inert across common laboratory solvents and buffers in routine use while keeping sample purity intact through the filtration pass and presses snugly against the membrane during the pass. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Low extractables keep the chromatographic background clean
• Absolute pore rating delivers reproducible retention across every protocol
• Solvent tolerance includes full-strength tetrahydrofuran and chlorinated solvents such as dichloromethane
• Ionic and metallic extractable levels stay very low
• Membrane integrity holds across repeated autoclave sterilization cycles at 121°C to 134°C

Housing Characteristics

• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure
• Translucent housing wall allows visual confirmation of sample flow during filtration
• Optimized internal geometry minimizes backpressure in service
• Plasticizer-free polyolefin construction keeps the fluid path clean

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.

• Trace Metals Analysis - PTFE's low metal-extractable profile clarifies acid-digested samples for clean, low-background ICP-MS and ICP-OES results.
• Mobile Phase Prep - Extends column life by consistently removing particulates from organic HPLC mobile phases before every injection.
• Polymer GPC Prep - Clarifies polymer solutions in THF ahead of gel permeation chromatography, protecting columns from particulates.
• Fuel Analysis Prep - Clarifies gasoline and other petroleum samples ahead of gas chromatography, protecting injector ports from residue buildup.
• Toxicology Screening - Clarifies protein-precipitated serum, plasma, and urine extracts ahead of LC-MS or GC-MS drug screening analysis.
• Battery Electrolyte Prep - Clarifies lithium-ion battery electrolyte in carbonate solvents ahead of GC-MS purity and impurity analysis.
