CA Syringe Filters, 0.45 um, 30mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF18286

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 100/Pk - SF18286

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Cellulose acetate holds a uniform pore structure for consistent results while minimizing protein binding for high analyte recovery and handles water-based samples and low-alcohol solutions. Polypropylene construction maintains housing integrity through the filtration run while sustaining efficient flow on viscous samples and keeps the fluid path low in extractable contamination. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Absolute pore-size rating gives consistent retention across protocols
• Very low protein binding supports high recovery of dilute samples
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Smooth surface with low extractables and a uniform pore structure
• Naturally hydrophilic surface wets readily with aqueous samples

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Resists stress cracking from aqueous salt and buffer solutions
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

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 from reagent and buffer preparation through routine sample clarification. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
