Tisch SKU: SF18290

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 5 µm, 30 mm, 100/Pk - SF18290

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Low-binding cellulose acetate preserves dilute proteins in the filtrate while drawing aqueous samples through readily and delivers absolute particle retention at the rated pore size. The polypropylene housing routes flow to minimize backpressure in service while holding extractables low for sensitive analyses and maintains housing integrity through the filtration run. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

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

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Stable across the full aqueous pH range in routine sample work
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service

• HPLC Mobile Phase Prefiltration - Removes particulates from solvents, protecting pump seals and column frits, extending instrument service intervals
• Cell Culture Media Clarification - Eliminates cellular debris from conditioned media, preserving secreted proteins for sensitive downstream analysis
• Analytical Sample Preparation - Protects LC-MS ion sources and HPLC columns from particulate fouling in complex biological and environmental samples
• Aqueous Buffer Filtration - Clarifies phosphate buffers and reagents without chemical interaction, maintaining pH stability throughout all processing
• Viscous Sample Processing - Handles thick solutions and emulsions that would clog finer membranes, allowing sample complexity without interruption
• Prefiltration Protection - Protects sterile membranes and analytical equipment from gross contamination, extending downstream 0.22 µm filter life
