EZ-Fit^® Filtration Units by Merck KGaA, Darmstadt, Germany

The EZ-Fit^® Filtration Unit is a disposable filtration device for bioburden testing of liquid samples including water, in-process samples, and final products.

The EZ-Fit^® Filtration Units have been designed to ensure optimal microbial recovery. The drain support and the funnel-to-base assembly have been optimized so that the membrane is perfectly flat after the sample filtration. When transferred to the culture media, the whole filtration surface of the membrane is in perfect contact with the culture media. No folds or membrane waves ensures optimal microbial recovery. The shape of the funnel and the plastic material minimize sample residue ensuring that the complete sample volume reaches the membrane surface. The innovative funnel assembly design prevents any leaks or sample by-pass of the membrane, meaning that the whole sample volume is filtered. The EZ-Fit^® Filtration Units conform to international standards (EP/USP) and comply with water testing regulations.

Benefits:

• Drain support and optimized funnel-to-base assembly ensure optimal microbial recovery
• The unique funnel design ensures that the whole sample volume is filtered
• The risk of contaminating the membrane with forceps is reduced to a minimum due to a continuous rim
• 250 ml funnels allow larger volume samples
