Inserting A Contact Plate Or Petri Dish - Cantium Scientific MicroBio MB2 Operating Manual

Inserting a Contact Plate or Petri Dish

Carefully remove the sampling head cover from
the MicroBio MB2, 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 support plate, then re-fit
the sampling head.
ALWAYS STERILISE THE SAMPLING HEAD
The standard MicroBio MB2 can use 220 or 400
hole sampling heads. The 220 hole sampling head
can be used with both 55mm/65mm contact plates
or 90mm petri dishes, but only the centre 55mm of
the petri dish will collect samples. Using the 400 x
0.7mm hole sampling head will give nearly full
coverage of a 90mm petri dish, improving reliability
of counts.
The MicroBio MB2-HiFlow model can only use
90mm Petri dishes and the 400 x 1mm hole
sampling head.
