GVS ABLUO PTFE Syringe Filters, 0.22 µm, 25 mm, 500/Pk - FJ25BNPPH002AD01

Every GVS syringe filter passes an integrity test confirming proper fit and weld, verification that the assembly is sealed against filter bypass. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. PTFE filters aggressive organic solvents without swelling or breakdown and accepts aqueous samples without alcohol pre-wetting. The polypropylene housing routes flow to minimize backpressure in service and leaves no seam for sample to bypass the membrane. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

Membrane Characteristics

• Hydrofluoric acid resistance holds even in fully acid-digested samples
• Absolute pore rating delivers reproducible retention across every protocol
• Chemical resistance spans the full pH 1 to 14 range
• Biological inertness resists enzymatic attack from proteases and lipases
• Inert composition offers no nutrient source for microbial growth

Housing Characteristics

• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Thermal-bonded construction keeps adhesives out of the fluid path
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

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 across the buffers and reagents your day-to-day prep depends on.

• Agrochemical Formulation QC - Clarifies technical pesticide concentrates in organic solvent ahead of HPLC potency and impurity analysis.
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, delivering pure filtrate quality consistently.
• Dissolution Testing - Stops the dissolution reaction and clarifies samples, with low API binding for accurate potency quantitation.
• 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.
• Fuel Analysis Prep - Clarifies gasoline and other petroleum samples ahead of gas chromatography, protecting injector ports from residue buildup.
