Model PSF-7100
Inquire productA colony counter is a laboratory device used to count colonies of microorganisms (bacteria), that have grown/multiplied on an agar plate prepared from a sample, usually in a Petri dish. Traditionally, the colonies were counted manually, but this method is time consuming and can lead to false results, because of human error. Using the modern automatic colony counters, 10 minutes manual counting could be completed within 5 seconds of automated counting.
For more efficient colony counter operation the special Petri Dish Handler (PDH series) can be used. It is the device, that can automatically transport Petri dishes to the colony counter device achieving high-speed measurement of 100 Petri dishes per hour.
