MCE Syringe Filter, 0.45um, 25mm, Double Luer-Lok, Sterile, 100/Pk SKU: SPEC18173

Mixed Cellulose Ester (MCE) Syringe Filter - SPEC18173

Biological samples and protein solutions often lose valuable material through adsorption to synthetic filtration membranes, compromising analytical accuracy and research outcomes. The SPEC18173 solves this challenge with a 0.45 µm mixed cellulose ester membrane that clarifies samples while maintaining naturally low protein binding characteristics essential for biomolecule recovery. Your operations benefit from cellulosic chemistry that removes particulates without the protein loss issues common to other membrane materials, while this sterile configuration with double Luer-Lok connections eliminates preparation steps in cell culture media processing, biological buffer clarification, protein solution filtration, and pharmaceutical quality control applications requiring reliable particulate removal with minimal sample loss.

Key Membrane Characteristics

• 0.45 µm mixed cellulose ester membrane provides clarification with naturally low protein binding for biomolecule preservation
• 4.08 cm² filtration area delivers efficient processing capacity for moderate sample volumes in clarification applications
• 29 psi bubble point ensures membrane integrity, while the hydrophilic cellulosic structure enables immediate aqueous sample processing
• Low extractables profile maintains solution purity during filtration of sensitive biological samples and pharmaceutical preparations
• Aqueous compatibility supports water-based buffers, biological fluids, and neutral pH solutions across laboratory applications

Key Construction Characteristics

• Durable polypropylene housing withstands operating pressures up to 72.5 psi with burst protection rated to 116 psi
• Double Luer-Lok inlet and outlet connections provide secure, leak-free attachment during filtration operations
• Each filter arrives gamma-sterilized and individually packaged to maintain contamination-free conditions until use
• Sterile-ready configuration eliminates preparation steps for immediate use in biological sample processing applications

Your clarification workflows gain efficiency from sterile-ready filters that eliminate preparation time while the mixed cellulose ester composition naturally resists protein adsorption. The 4.08 cm² filtration area processes moderate sample volumes appropriately for clarification applications requiring biomolecule preservation. Double Luer-Lok connections maintain secure attachment during processing operations while the hydrophilic membrane chemistry supports diverse aqueous applications across pharmaceutical, biotechnology, and analytical testing laboratories.
