Mixed Cellulose Esters (MCE) Syringe Filters - SPEC18169

Laboratories processing protein solutions and biological samples often face the challenge of protein adsorption to synthetic membranes. The SPEC18169 addresses this with a 1.0 µm mixed cellulose ester membrane. Such a structure provides coarse prefiltration while maintaining the naturally low protein binding characteristics essential for biomolecule preservation. Workflows benefit from cellulosic chemistry that removes larger particulates without the protein loss common to other membrane materials. Double Luer-Lok connections ensure secure attachment during processing of fermentation broths, tissue homogenates, and viscous biological fluids requiring initial clarification.

Key Membrane Characteristics

• A 1.0 µm mixed cellulose ester membrane delivers coarse prefiltration with naturally low protein binding for biomolecule preservation
• The 4.08 cm² filtration area processes moderate sample volumes efficiently for routine laboratory prefiltration operations
• Validated 7.25 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 in-house sterilization protocols when preparing filters for specific applications
• Nonsterile configuration offers flexibility allowing sterilization before use or employment for routine sample preparation

Your prefiltration operations gain reliability from the mixed cellulose ester composition that naturally resists protein adsorption. Protein recovery remains critical when processing valuable biological samples. The 4.08 cm² filtration area handles moderate sample volumes appropriately while the 1.0 µm pore size removes coarse particles that would clog finer downstream membranes. Double Luer-Lok connections maintain secure attachment throughout processing. Autoclavable construction and hydrophilic membrane chemistry support your diverse applications across pharmaceutical, biotechnology, and clinical testing laboratories.
