The non-fermenting Total Viable Count (TVC) Vials allows for greater inclusivity with a shorter detection time in sterility testing. As organisms grow in the broth medium, the carbon dioxide (CO2) produced diffuses through a membrane layer into a soft agar plug containing a dye indicator. The colour change in the dye is read by the Soleris instrument. The membrane layer also serves as a barrier, eliminating product interference with the reading frame.

In an AOAC Research Institute Performance Tested MethodSM study, the Soleris® NF-TVC vial was found to be an effective procedure for semiquantitative determination of total aerobic count in the following sample types: raw chicken, deli ham, lettuce, almonds, black pepper, cheesecake, ice cream mix, nonfat dry milk and cocoa powder. Test duration is 24 hours, with the exception of cocoa powder, which is 27 hours.
