According to Cole-Parmer, the pleated band membranes offer the same quality and reliability as individually wrapped MCE membranes and provide hands-free convenience and increased efficiency as well as reducing the risk of membrane contamination from handling. They have been designed for use in applications such as the microbiological examination of water, wastewater, pharmaceuticals, food, and beverages. The membrane not only has high recovery rates, but its high porosity provides superior flow rates as well.The company says that benefits of the membrane include that it is available in 0.45μm and 0.80μm pore sizes. There is also a choice of membranes - gridded surface white for the examination of water and wastewater and applications in the pharmaceutical, medical, food and beverage industries, and black for the examination of bottled water, carbonated beverages, beer and wine. The membranes are pre-sterilized and ready to use, and there are 100 individually sealed filters in a continuous pleated band.
