Inoculate Every container with one of the ready and standardized inoculum, and mix.
There is a time-consuming method and a quick method. Time-consuming way requires employing a spectrophotometer or turbidimeter to acquire the correct concentration.
Transfer the sterile tubes/flasks that contains media into a micro LAF bench and allow it to chill to area temperature.
