EZ-Fit Filtration Unit for bioburden testing

The EZ-Fit Filtration Unit is a ready-to-use, disposable filtration device for bioburden testing. The unit, which conforms to international standards (EP/USP) and water-testing regulations, can be used for filtration of liquid samples including water, raw materials, in-process samples and final products.

The filtration unit delivers optimal microbial recovery and reliable results. The shape of the funnel and the plastic material minimise sample residue to ensure that the complete sample volume reaches the membrane surface. The design reduces the risk of leaks and prevents sample from bypassing the membrane to allow filtration of the entire volume. Following sample filtration, the membrane is perfectly flat; when transferred, the entire surface of the membrane is in contact with the culture media. Alternatively, liquid media can be added from the top and once the funnel is removed, the device converts into a petri dish for faster, more convenient incubation.

The unit is pre-sterilised and the lid remains in place during filtration to prevent contamination. To further maintain sample integrity, a rim prevents forceps from accidentally touching the membrane filtration area during transfer.

The unit allows one-handed funnel removal, and the clear funnel with a large diameter enables easy sample pouring and visualisation of the end of filtration. Level indicators on the funnel eliminate the need to turn it when placing on the filtration support.

The units are available in 100 or 250 mL funnel sizes and are stackable to save space in the laboratory.
