MCE Syringe Filter, 3.0um, 20mm, Double Luer-Lok, Sterile, 100/Pk SKU: SPEC18185

Mixed Cellulose Ester (MCE) Syringe Filter - SPEC18185

Heavily particulate biological samples often clog downstream filters prematurely, while synthetic membranes adsorb valuable proteins, creating dual challenges in sample preparation workflows. The SPEC18185 solves both issues with a 3.0 µm mixed cellulose ester membrane that removes coarse particles while maintaining naturally low protein binding characteristics essential for biomolecule preservation. Your operations benefit from cellulosic chemistry that handles large suspended solids without the protein loss common to other membrane materials, while this sterile configuration with double Luer-Lok connections eliminates preparation steps in turbid sample prefiltration, high-density fermentation monitoring, tissue extract processing, viscous biological fluid clarification, and pharmaceutical quality control applications.

Key Membrane Characteristics

• 3.0 µm mixed cellulose ester membrane provides coarse prefiltration with naturally low protein binding for biological sample processing
• 3.1 cm² filtration area in the 20mm diameter configuration handles routine laboratory sample volumes efficiently
• 4.35 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
• Broad chemical compatibility supports aqueous buffers, alcohols, and mild organic solvents across diverse laboratory applications

Key Construction Characteristics

• Durable acrylonitrile butadiene styrene 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 coarse prefiltration workflows gain efficiency from sterile-ready filters that eliminate preparation time while the mixed cellulose ester composition naturally resists protein adsorption. The 3.1 cm² filtration area processes routine laboratory sample volumes appropriately while the 3.0 µm pore size handles heavily particulate samples that would compromise finer membranes. Double Luer-Lok connections maintain secure attachment during processing, supporting diverse applications across pharmaceutical, biotechnology, and environmental testing laboratories requiring reliable coarse particle removal with biomolecule preservation.
