6.4.6. STACKING STERILIZATION CONTAINERS
When arranging sterilization containers, care
should be taken that drops of condensate do
not wet items being sterilized beneath, but
can flow away to the base of the chamber. The
best arrangement is a stack of sterilization
containers of the same size, so that
condensate can flow down the sides.
