Mixed Cellulose Ester (MCE) Syringe Filter - SPEC18181
Heavily particulate samples often clog finer membranes prematurely while synthetic materials adsorb valuable proteins, creating dual challenges in biological sample processing. The SPEC18181 solves both issues with a 5.0 µm mixed cellulose ester membrane that removes coarse particulates while maintaining naturally low protein binding characteristics essential for biomolecule recovery. Your operations benefit from cellulosic chemistry that handles large suspended solids without the protein loss common to other membrane materials, while double Luer-Lok connections ensure secure attachment during environmental water testing, high-density fermentation monitoring, tissue extract processing, viscous biological fluid clarification, industrial sample preparation, and pharmaceutical quality control applications requiring reliable coarse prefiltration.
Key Membrane Characteristics
- 5.0 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
- 2.9 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
- 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 coarse prefiltration workflows gain reliability from the mixed cellulose ester composition that naturally resists protein adsorption during particle removal. The 3.1 cm² filtration area processes routine laboratory sample volumes appropriately while the 5.0 µm pore size handles heavily particulate samples that would overwhelm finer membranes. 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.
