Disposable filtration units handle a range of fluids
MilliporeSigma
This company has recently expanded its portfolio of EZ-Fit filtration units (photo). These ready-to-use, disposable filtration devices are designed for bioburden testing. The newer EZ-Fit pink filtration units come with a wide range of membrane sizes to suit many applications, and they feature a new patented drain design to accelerate processing of turbid or hard-to-filter matrices. Both the newer pink and the original blue units are said to conform 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 and 250-mL funnel sizes. The optimized membrane remains perfectly flat after filtration to stay in constant contact with the culture media, says the manufacturer. — MilliporeSigma, Billerica, Mass.
