3M菌落总数测试片/ 3M™ Petrifilm™ Aerobic Count Plates
Within 48 hours (U.S. AOAC®) the 3M™ Petrifilm™ Aerobic Count Plate helps determine aerobic bacteria populations. Using a simple procedure this plate also helps detect lactic-acid bacteria.
The 3M™ Petrifilm™ Aerobic Count Plate enumerates total aerobic bacteria present in the sample tested. Following a simple protocol they can also be used for enumerating anaerobic bacteria for processed meats and in high acid foods. Fast, Accurate, Results in 48 hours (U.S. AOAC®) with three easy steps:
1) Inoculate - 3M™ Petrifilm™ Plates are easy to inoculate. Lift the top film and add sample
2) Incubate - The space saving design maximizes incubator space.
3) Enumerate - A red indicator dye in the plate colors all colonies red. This Petrifilm Plate can also be read in 4 seconds using the 3M™ Petrifilm™ Plate Reader.
