Merck Millipore, the Life Science division of Merck, 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 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," notes 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." 

The EZ-Fit™ Filtration Unit delivers optimal microbial recovery and more reliable results. The shape of the funnel and the plastic material minimize 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-sterilized 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 EZ-Fit™ Filtration Unit allows one-handed funnel removal. In addition, the clear funnel with a larger diameter enables easier sample pouring and visualization 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 100 mL or 250 mL funnel sizes and are either individually bagged or packaged in bulk. Additionally, the units are stackable to save space in the laboratory. 

EZ-Fit™ Filtration Units are easily integrated with the EZ-Fit™ Manifold, a universal laboratory filtration system, and are part of the EZ-product family designed to facilitate microbiology workflow in quality assurance and quality control (QA/QC) laboratories. Other products include:  

• EZ-Fluo™ Rapid Detection System: faster, non-destructive detection of microbial contamination
• EZ-Pak® Dispenser Curve: high-speed, sterile membrane dispensing with no-touch operation
• EZ-Stream™ Pump: direct transfer of liquids to eliminate repeated handling of liquid waste containers
