Nylon Syringe Filters w/ GD-4 Pre-Filter, 0.45um, 25mm, Nonsterile, 100/Pk
Tisch SKU: GD17034

Tisch Scientific Nylon Syringe Filters, 0.45 µm, 25 mm, 100/Pk - GD17034

Tisch Scientific customer service specialists focus on laboratory products and can help source the right solution for specific applications. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Nylon includes a built-in prefilter that sustains flow on high-particulate samples while shipping in economical bulk non-sterile packaging and wets on contact with aqueous samples. The polypropylene housing holds a reliable seal against the membrane edge while keeping the fluid path low in extractable contamination and routes flow to minimize backpressure in service. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Non-sterile for routine clarification and sample prep
• Low extractable contribution to sensitive analytical preparations
• Alkaline-resistant across a broad range of aqueous buffers
• Integrated glass-fiber prefilter increases dirt-holding capacity

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Stable across the full aqueous pH range in routine sample work
• Low extractable contribution protects sensitive downstream analyses

Filtering particulates upstream protects the column investment your methods depend on. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
