Inserting a Contact Plate or Petri Dish
Carefully remove the sampling head cover from the MicroBio MB1, unless it
is being carried separately in a sterile container. Only hold the edge of the
head. Do not touch the perforated or inside surfaces.
With the sampling head removed, insert a petri dish / contact plate inside the
springs, so that its base sits firmly on the three support posts, then re-fit the
sampling head.
