Designed for rapid and accurate counting of bacterial and mould colonies.
The Stuart colony counter is easy to use. Simply place the Petri-dish on the electronic pressure pad and touch the dish with a felt tip pen to mark each colony in turn. Touch pressure causes a count to be registered on the digital display and an audible tone confirms each count made. Marking the dish with a felt tip pen avoids missing colonies or double counting, although any suitable implement may be used to apply pressure to the dish. The sensitivity of the electronic pressure pad is adjustable to suit the user.
