The EZ-FIT® Filtration Units are disposable filtration devices designed to ensure optimal microbial recovery. These sterile, single-use filtration devices are made of white, gridded, and mixed cellulose esters (MCE) membrane with a pink base. They streamline the workflow, save time, and provide highly reliable microbial enumeration results. The filters prevent any leaks or sample by-pass of the membrane. The samples are covered by a vented lid throughout filtration and protected from contamination by a 360° rim that prevents forceps from accidentally touching the membrane filtration area. The clear and transparent funnel material ensures the visualization of the filtration process at any angle, until the end. These filtration units can be stacked to save the work area and minimize the sample residue. They are disposable and designed to fit onto the EZ-FIT® Manifold, featuring specific EZ-FIT® Filtration heads. They can also fit onto a standard #8 stopper. The bulk packaged units are provided with a protective plastic bag. Application EZ-FIT® filtration units are used to detect Yeasts and molds in liquid samples, including in process and final product samples (beverages, pharmaceuticals, and water). They are also used in industrial QC and water monitoring.
