General description

The EZ-FIT® filtration unit is a single-use filtration device made of black, gridded, and mixed cellulose esters (MCE) membrane with pink base. It provides a safe and fast way of performing membrane filtration, by avoiding the exposure to the risks of microbiological analyses. These filtration units are designed for optimizing and securing the laboratory workflow to provide time saving and reliable microbial enumeration results. The innovative funnel assembly design prevents any leaks or sample by-pass of the membrane. The filtration units are pre-sterilized, a vented lid covers the sample throughout filtration, and a 360° rim prevents forceps from accidentally touching the membrane filtration area during membrane transfer, to protect samples from contamination. The end of filtration process can be visualized from any angle through the clear, and transparent funnel material. The EZ-FIT® filtration units conform to international standards and minimize sample residue. The units can be stacked to save the work area. This disposable device is designed to fit onto the EZ-FIT® Manifold, which features specific EZ-FIT® Filtration heads. It can also fit onto a standard #8 stopper.


The EZ-FIT® filtration units are used in general microbiological analysis such as bioburden testing of liquid samples including in process and final product samples in beverages, pharmaceuticals, and water. These products are also used in industrial QC and water monitoring.
