A Mixed Cellulose Ester (MCE) syringe filter is a laboratory filtration device used to remove particles or microorganisms from liquids before analysis. It’s a disposable filter unit that connects to the end of a syringe and is commonly used for filtering aqueous solutions. An MCE syringe filter is a disposable, membrane-based device used primarily in laboratories for the sterile or non-sterile filtration of liquids. “MCE” stands for Mixed Cellulose Ester, a common filter membrane material.
