Microbial Testing Without the Burden: New EZ-Fit™ Filtration Units from Merck

Merck has expanded its portfolio of EZ-Fit™ filtration units, ready-to-use, disposable filtration devices for bioburden testing. The new EZ-Fit™ filtration units come with a wide range of membrane sizes to suit all applications, and a new patented drain design to accelerate processing of turbid and hard-to-filter matrices.

The full portfolio, including the new units, conforms to international standards (USP/EP) and water testing regulations, and can be used for filtration of liquid samples including water, raw materials, in-process samples and final products. They are available in 100 mL or 250 mL funnel sizes.

Advantages of EZ-Fit™ filtration units include:

• Optimized membrane remains perfectly flat after filtration to stay in constant contact with culture media
• Unique funnel shape and hydrophobic material minimize residue and maximize sample volume
• Innovative funnel assembly eases sample collection and prevents leaks
• Stay-in-place lid prevents contamination during filtration
• Specialized rim design keeps forceps away from filtration area during transfer forceps from accidentally touching the membrane filtration area during transfer
• Easy manifold access enables better cleaning
• Transparent funnel design allows user to see when filtration is complete from any angle
• Unique membrane base shape enables easy membrane transfer
• Stackable units save space in the work area
