Ready-to-use filtration unit offers more efficient bioburden testing

EZ-Fit reduces risk of sample contamination associated with filtration and membrane transfer, accelerates filtration process and delivers more reliable results

The unit delivers optimal microbial recovery and more reliable results

Merck Millipore has launched the EZ-Fit Filtration Unit, a ready-to-use, disposable filtration device for bioburden testing. The system is faster and more efficient than traditional methods, resulting in increased reliability and streamlined workflows. 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 unit delivers optimal microbial recovery and more reliable results, the company says. 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 by-passing 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 EZ-Fit Filtration 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. To facilitate operation and save time, the funnel can be removed one-handed. In addition, the clear funnel with a larger diameter enables easier 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.

EZ-Fit Filtration Units are available in 100mL or 250mL funnel sizes and are either individually bagged or packaged in bulk. Additionally, the units are stackable to save space in the laboratory. They are easily integrated with the EZ-Fit Manifold, a universal laboratory filtration system.

'The EZ-Fit Filtration Unit represents the latest addition to our comprehensive portfolio of products that facilitate and simplify the microbiology workflow while helping to reduce the risk of contamination,' said John Sweeney, Head of Lab Solutions, Merck Millipore. 'Bioburden testing is an essential element of quality control. To meet the evolving needs of this critical process, we will continue to leverage our strong legacy and expertise in the area of filtration, delivering innovative solutions for QC professionals.'
