Colony Counter Machine In Hindi

Colony counter •A colony counter is an instrument used to count colonies of ,bacteria or other microorganisms growing on an agar plate. •An instrument designed to conveniently count or assist counting colonies of microorganisms on a plate containing a gelled growth medium. One variety uses a pencil-like rod with a metal tip, which is connected by an electrical connection to the gelled growth medium; when touched to a colony on the plate, the completion of the electrical circuit causes an increment of 1 unit on the readout of the colony counter. Early counters •Early counters were merely lighted surfaces on which the plate was placed, with the colonies marked off with a felt-tipped penon the outer surface of the plate while the operator kept the count manually. Recent counters More recent counters attempt to count the colonies electronically, by identifying individual areas of dark and light according to automatic or user-set thresholds, and counting the resulting contrasting spots. Procedure 1.Place the Petri-dish on the colony counter. 2. Count a Petri-dish by clicking the count button on the software. 3.The results will be displayed indicating the number of colonies. The Recent Colony Counter •The automatic colony counter has the ability to separate the image of combined colonies for the user to magnify each colony. •The recent colony counter is connected to a PC. The Old Colony Counter 1.Place the colony counter on the lighted surface with the colonies marked off with a felt-tipped pen on the outer surface. 2.Keep the count manually The Old Colony Counter 1.Place the colony counter on the lighted surface with the colonies marked off with a felt-tipped pen on the outer surface. 2.Keep the count manually Comparison Recent •Is indeed faster and easier to use •More efficient for observation Old •Hard to use •Manual counting •Not so efficient compare to the recent
