When developing antimicrobial products for disinfection of biofilms, the methods and tests you use are very important. These must be standardized to ensure product claims are true and relevent. The USEPA is the government body in charge of these regulations in the United States, and it is up to them to provide methods, procedures, and guidance on this subject. (See the full list of current antimicrobial testing methods and procedures at the USEPA website.)      In May, the USEPA announced the release of two new methods regarding biofilm disinfection: MB-19 and MB-20. The first of these describes the methods used to grow a bacterial biofilm under high shear conditions using the CDC Biofilm Reactor. The second describes how to use the single tube method (described in ASTM E2871-13) to determine the efficacy of disinfectants against bacterial biofilms grown in the CDC Biofilm Reactor. We are excited to see the CDC Biofilm Reactor becoming a staple in biofilm testing, both in the United States and around the world.      To see more about the CDC Biofilm Reactor, visit the product page, and contact us for a quote or to place an order.
