  • Availability by Geography
  • United StatesJapanCanadaEuropeAustraliaThailandMalaysia
  • Background Information
  • Available in 4, 13, 25, 33, and 50 mm diameters with a variety of membranes, Millex® sterile syringe filters are ideal for sterilizing organic solvents, aqueous solutions or air/gas. Many sample preparation methods specify Millex® filters because of their unsurpassed quality and consistency. Millex® filters not only feature minimal hold-up volume and faster flow rates, but they also withstand higher operating pressures and are chemically compatible with a range of samples and solvents to minimize leaching of extractable impurities. Millex® filters are produced in a controlled, automated environment with the highest quality standards. Sterile devices come with a certificate of quality, with select devices marked for medical applications.Features & Benefits:•Tailored to a variety of applications based on membrane type, housing and validation rating •Medical Device-rated devices in some countries including vented devices for direct patient care •Specialized filter units to protect hemodialysis transducers from blood and moisture and for vacuum line protection •Low extractables and low absorption membranes for minimum sample losses •Faster flow rates and higher operating pressures for high performance needs Applications:Sterilization of Aqueous Solutions, Organic Solvents and Gases, Filtration of High Value Protein or Small Molecule Components, Select Medical Device Applications (Some Including Direct Patient Care Depending on Country/Region)
