It is designed to prevent the dishes from slipping when liquified agar medium is poured in a stack-pouring manner. This Petri dish is handled manually and is not compatible with most automatic plate-pouring systems. Semi-stackable Petri dishes, or slippable, beveled lid Petri dishes, have a slightly raised leveled ridge than fully stackable Petri dishes, which allow them to be used manually and automatically by plate-pouring machines.
