Mixed Cellulose Esters (MCE) Syringe Filters - SPEC18168

SPEC18168 syringe filters feature naturally low protein-binding characteristics through their 0.45 µm mixed cellulose ester membrane, which clarifies biological samples while preserving biomolecule recovery. Its hydrophilic cellulosic structure removes particulates from aqueous solutions without the protein adsorption issues common to synthetic membranes, making it ideal for processing enzyme preparations, antibody solutions, and cell culture components. Laboratories benefit from this 25mm configuration with double Luer-Lok connections that ensure secure attachment during clarification of protein solutions, biological buffers, and pharmaceutical formulations.

Key Membrane Characteristics

• A 0.45 µm mixed cellulose esters membrane provides clarification with naturally low protein binding for biomolecule preservation
• The 4.08 cm² filtration area in the 25mm diameter delivers efficient processing capacity for moderate sample volumes
• Validated 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
• 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

Your clarification workflows gain efficiency from the mixed cellulose esters composition that naturally resists protein adsorption, critical when processing valuable biological samples. The 4.08 cm² filtration area handles moderate sample volumes appropriately for routine laboratory processing operations. Double Luer-Lok connections maintain secure attachment throughout filtration while the nonsterile configuration provides flexibility for autoclavable preparation when required, supporting diverse aqueous applications across pharmaceutical, biotechnology, and analytical testing laboratories.
