GVS ABLUO PTFE Syringe Filters, 0.45 µm, 25 mm, 500/Pk - GF25BNPGT004AD01

GVS casts its own microporous membranes and assembles them into finished syringe filters under one roof, rather than sourcing either component externally. Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. The PTFE matrix handles concentrated acids and bases across demanding methods while maintaining absolute retention consistency at every rated size and resists attack from the harshest process chemistries. The creep-resistant MBS matrix stays pressed firmly to the membrane while taking hand pressure without cracking and tolerates aqueous acids, bases, and alcohols during standard prep. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Prefiltration

• Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
• Added glass fiber stage extends usable throughput by delaying membrane clogging
• Depth-loading glass fiber matrix captures particulate throughout its full thickness
• High dirt-holding capacity suits very turbid, high-solids sample loads

Membrane Characteristics

• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Ionic and metallic extractable levels stay very low
• Chemical resistance spans the full pH 1 to 14 range
• Non-wetting pore surface blocks liquid water while passing water vapor freely
• Stable across a wide operating temperature range for demanding methods

Housing Characteristics

• Bisphenol-A-free composition keeps background signal out of trace-level BPA and endocrine-disruptor testing
• Methacrylate surface hardness paired with butadiene impact strength
• Handles aqueous acids, bases, and alcohols without issue during sample prep
• The housing keeps full contact with the membrane, so no sample passes around it

An aggressive solvent can leach or break down a vulnerable filter and carry debris into your prep. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run.
