Mixed Cellulose Ester (MCE) Syringe Filter - SPEC18170

Pharmaceutical, biotechnology, and industrial laboratories require coarse prefiltration solutions that protect downstream membranes and analytical instrumentation from premature fouling by suspended solids. The SPEC18170 meets these industry demands with a 3.0 µm mixed cellulose ester membrane that removes larger particulates while maintaining the naturally low protein binding characteristics essential for biological sample processing. Your operations benefit from this design approach that combines coarse particle removal with cellulosic chemistry, delivering reliable prefiltration for heavily particulate samples across environmental testing, fermentation monitoring, tissue extract processing, and viscous fluid analysis where protecting finer downstream filters extends operational life and reduces processing costs.

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 laboratory 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
• Autoclavable construction supports your in-house sterilization protocols when preparing filters for specific applications
• Nonsterile configuration offers flexibility where you can sterilize filters before use or employ them for routine sample preparation

Quality assurance comes from the mixed cellulose ester composition that naturally resists protein adsorption while the 3.0 µm pore size handles heavily particulate samples. The 4.08 cm² filtration area processes moderate sample volumes appropriately for coarse prefiltration applications that protect downstream filters and instrumentation. Double Luer-Lok connections maintain secure attachment during processing while autoclavable construction and hydrophilic membrane chemistry support diverse applications across pharmaceutical, biotechnology, and environmental testing laboratories requiring reliable coarse particle removal.
