Science First Colony Counter
Description

Microorganisms are far too small to count with the naked eye and hence to offer easy counting of colonies colony counter is used. Place your sample of microorganisms into a petri dish and place it on the lighted base. Arranged in an “X” pattern from corner to corner, the squares are broken down into nine smaller squares, each one third of a centimeter on a side. Add these counts together and divide by the number of squares counted, this will yield an average colony count per square. Take five or ten squares at random and count the number of colonies in each. This colony counter contains lighted base, counter overlay and instructions.
