Interest in aseptic filling lines is constantly growing. You need tools that are sound, fast and easy to use, and most of all standardised, not only for monitoring purposes but also for annual line checks for reliability or even for possible contaminants. AVM® (aseptic validation medium) is Döhler's solution. AVM is supplied either as a powder concentrate or as a ready-to-use product. For validation in your aseptic filling line, AVM is filled into your system in a ready-to-use form.  After short incubation of the filled bottles cloudiness is your quick indicator of a possible contamination.
