incubation

  1. L

    why does a petri dish have to be left for a short while ( 1 hour) b4 incubation?

    well, if it wasn't kept in the fridge. i mean, if the agar was poured into it, left to cool, then the bacterial solution is added and the lid placed on the dish, why does it need to be kept outside the incubator b4 incubation?
