Colony Counting

In microbiology, a colony-forming unit is used to estimate the number of viable bacteria or fungal cells in a sample. Viable is defined as the ability to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells.
ProtoCOL is a comprehensive and fully automatic colony counting and zone sizing system specifically designed for microbiology and virology applications. This colony counter and zone sizer system is suitable for reading a wide range of types of microbiology and virology media. Colonies can be automatically counted on standard pour plates, surface inoculated plates, spiral plates, 3M ™ Petrifilm ™, filters, culture flasks and numerous other media.
aCOLade
The new aCOLade 2 manual colony counter is an ideal choice for budget-conscious microbiology laboratories. It consists of an illuminated receiver plate and a large LED display. The pressure of marking a colony with a felt-tip pen registers a cumulative count on the digital display with confirmation by audible tone (can be turned on or off). The pressure required to register a count can be adjusted to suit each user.
