CA Syringe Filters w/ 3 Pre-Filters, 0.45 um, 25mm, Sterile, 100/Pk
Tisch SKU: SF18295

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF18295

Tisch Scientific keeps ordering simple, turning quotes and questions around quickly. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Low-extractable cellulose acetate keeps filtrate clean ahead of analysis while suiting aqueous solutions, buffers, and alcohols in routine use and keeps protein adsorption very low across the run. The PP housing stays inert across common laboratory solvents and buffers in routine use while holding a reliable seal against the membrane edge and maintains a low-dead-volume internal flow path. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Naturally hydrophilic surface wets readily with aqueous samples
• 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
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Thermal-bonded construction keeps adhesives out of the fluid path
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
