Membrane Filtration Other Prepared Media

Hach’s ready-to-use media eliminates measuring, mixing, and autoclaving steps necessary to prepare dehydrated media. Membrane fi ltration methods enable the isolation and counting of microorganisms by fi ltering a sample through a membrane and then culturing it on microbial media. This technique is useful for testing large liquid volumes, making it crucial for environmental monitoring and water quality assessment. Compared to traditional methods, membrane fi ltration is faster and more e ffi cient, delivering results within 24 hours. Using selective media, speci fi c bacteria can be isolated, providing quantitative data on microbial load. This versatile technique is applicable to various samples, including water, beverages, and pharmaceuticals.
