Nylon Syringe Filters w/ GD-4 Pre-Filter, 0.22um, 25mm, Nonsterile, 100/Pk
Tisch SKU: GD17033

Tisch Scientific Nylon Syringe Filters, 0.22 µm, 25 mm, 100/Pk - GD17033

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The nylon membrane resists alkaline conditions across a broad buffer range and draws aqueous buffers through without pre-wetting. Polypropylene construction holds extractable contribution low for sensitive analyses while routing flow to minimize backpressure in service and stays inert across common laboratory solvents. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Absolute pore size rating provides consistent results across filtration protocols
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Integrated glass-fiber prefilter increases dirt-holding capacity

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Stable across the full aqueous pH range in routine sample work
• Resists stress cracking from aqueous salt and buffer solutions

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods. Connect with our customer support technicians for chemical compatibility guidance and the right filtration product for your workflow.
