Automatic
Plate Counting
The Ames Study Manager can run in conjunction with the Sorcerer
automatic colony counting system to create a total
solution for the Bacterial Reverse Mutation Test. Sorcerer
combines sophisticated image processing and analysis with an innovative
Petri-viewer to provide fast, accurate counts
of revertant colonies.
 The
small footprint Petri-viewer utilises incident, transmitted &
dark-field illumination to facilitate counting on all combinations
of test substances in Vogel-Bonner or alternative media. The use
of cool white light ensures excellent contrast
between colonies and substrate. The CCD camera and automatic
lens relay a live image of the sample to the computer screen.
In routine use, the user positions the cursor on the row of the
plate to be counted and places the sample in the Petri-viewer. The
Sorcerer system displays an image of the plate on-screen with a
coloured overlay indicating detected colonies. A
single press of the space bar initiates the count, which
is returned automatically and inserted into the Count cell of the
selected row.
