JL-1/1C   JLY-2/2C Colony counter

Colony counter is a kind of digital display semi-automatic bacteria inspection instrument. It is composed of counter, probe pen and counting pool. The counter is designed and manufactured by CMOS integrated circuit. In the counting pool with black depth background, the energy-saving ring lamp is used for side lighting, and the bacterial colony contrast is clear. According to the bacterial count test procedure, the instrument display is designed as a three-digit number. When the number of bacterial colonies in a petri dish exceeds 999, the test sample shall be diluted and redone to ensure the accuracy of the count.

 This instrument can reduce the labor intensity of the experimenter and improve the efficiency and quality of work. Products are widely used in food, beverage, medicine, biological products, sanitary products, drinking water, industrial wastewater, clinical specimens in the number of bacteria test. It is a necessary instrument for health and anti-epidemic stations, environmental monitoring stations, food hygiene supervision and inspection institutes, hospitals, biological products institutes, drug inspection institutes, food factories, daily chemical factories, colleges and universities, and laboratories of scientific research institutes.
