MCE Syringe Filter, 3.0um, 25mm, Double Luer-Lok, Sterile, 100/Pk SKU: SPEC18175

Mixed Cellulose Ester (MCE) Syringe Filter - SPEC18175

The SPEC18175 combines a 3.0 µm mixed cellulose ester membrane with 4.08 cm² filtration area and 4.35 psi bubble point, engineered for coarse prefiltration of heavily particulate biological samples. This hydrophilic cellulosic membrane removes large suspended solids while maintaining naturally low protein binding characteristics that preserve biomolecule recovery during sample processing. Your sterile-ready laboratory operations span turbid environmental sample processing, high-density fermentation monitoring, tissue homogenate clarification requiring coarse debris removal, viscous biological fluid prefiltration, cell culture harvest where secreted proteins must be preserved, and pharmaceutical quality control applications where protecting downstream analytical membranes from premature fouling extends operational life while maintaining sample integrity throughout processing workflows.

Key Membrane Characteristics

• 3.0 µm mixed cellulose ester membrane provides coarse prefiltration with naturally low protein binding for biological sample processing
• 4.08 cm² filtration area handles moderate sample volumes efficiently for routine coarse prefiltration operations
• 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
• 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

Quality assurance comes from the mixed cellulose ester composition that naturally resists protein adsorption during coarse prefiltration operations. The 4.08 cm² filtration area processes moderate 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 throughout processing while the sterile-ready configuration eliminates preparation time, supporting diverse applications across pharmaceutical, biotechnology, and environmental testing laboratories requiring reliable coarse particle removal with biomolecule preservation.
