XK97-A Semi-Automatic Colony Counter, 0-999 Count Range (CAT#: STEM-BC-3905-ZJF)

The XK97-A is a digital semi-automatic colony counter for microbiological examination. It is suitable for counting bacteria in food, beverages, medicines, biological products, drinking water, wastewater, and clinical specimens. The instrument consists of a counter, counting pens, and an illuminated counting chamber. Colonies are registered by pressing the counting pen against the bottom of the culture dish. A black recessed background and circular LED illumination provide uniform light and clear colony contrast. The gridded counting plate helps users observe and locate individual colonies. The supplied counting pens allow counted colonies to be marked while the total is recorded. A CMOS integrated circuit supports digital counting from zero to 999. The instrument helps reduce repetitive manual workload and improve counting efficiency.
