CC-N50/ CC-N50A colony counter is a digital display automatic bacteria testing instrument. It consists of counter, probe, counting chamber and other parts. The counter is carefully designed with CMOS integrated circuit, LED digital tube display, the character height is 13mm, clear and bright; It cooperates with a special probe, and the counting is sensitive and accurate. In the counting chamber with black background, the fluorescent light is illuminated, and the colony contrast is clear, which is easy to observe.This instrument can reduce the labor intensity of laboratory personnel, improve work efficiency, and improve work quality. It is widely used in food, beverage, medicine, biological product, cosmetic, sanitary product, drinking water, domestic sewage, industrial wastewater, and bacterial counts in clinical sample. It is a necessary instrument for epidemic prevention stations, environmental monitoring stations, food hygiene supervision and inspection institutes, hospitals, biological products institutes, drug inspection institutes, commodity inspection bureaus, food factories, beverage factories, cosmetics factories, daily chemical factories at all levels, as well as laboratories of colleges, universities and scientific research institutions
Put the culture dish on the white-light board, turn on the white light light, using probe by touching the dish to count, and the LED display will display the counted number; After the counting is completed, the counting pen can be used to temporarily record the total number on the manuscript paper, and then quickly turn off the power again, seeing the number return to zero from the LED screen.Comparing the second count with the previous total on the manuscript paper, the same number can get a more accurate result.
( Note )According to the bacteria count inspection regulation, when the number of bacteria in a petri dish exceeds 300, the test sample should be diluted and redone to ensure the accuracy of the count. Therefore, the instrument counts as three digits.
