XK97-A colony counter is a digital display semi-automatic bacteria counting instrument. It is composed of counting pool, counting pen, counter and digital display. The counting pool has a black background and is illuminated sideways by an energy-saving circular fluorescent lamp. The colony contrast is clear, and the pool surface has a certain inclination for easy observation. The instrument is easy to operate and counts accurately, which can reduce the labor intensity of experimenters, improve work efficiency and improve work quality. The instrument is widely used in food, beverage, medicine, biological products, cosmetics, sanitary products, drinking water, domestic (CN) sewage, industrial wastewater, and the detection of bacterial counts in clinical specimens.

"Note" According to the provisions of the bacteria counting test regulations, if the number of colonies in a petri dish exceeds 300 hours, the test sample should be diluted and redone to ensure the accuracy of counting.
