Overview
Colony counter is a digital display semi-automatic bacterial inspection instrument, which consists of a counter, a probe pen, a counting pool and other parts. It is designed and manufactured with CMOS integrated circuit, and the black deep background counting pool is illuminated by energy-saving ring lights to make the colony contrast clear. The instrument can reduce the labor intensity of the experimenter, improve the work efficiency and work mass.
Features
1. Adopt CMOS integrated circuit design and manufacturing to ensure accurate and reliable counting
2. Black depth background counting tank with energy-saving ring light side-shot lighting, clear colony contrast
3. Three-digit display design, in line with the requirements of bacterial count inspection procedures
4. Semi-automatic operation to reduce the labor intensity of experimenters
5. Compact structure for easy laboratory use
Principle
The instrument counts the colonies one by one at the bottom of the culture dish through the probe pen. Each point of an effective colony will issue a "beep" prompt. At the same time, the colonies are marked with Color, and the display numbers are automatically accumulated. After the counting is completed, the number on the display screen is the number of colonies in the culture dish.
Applications
Food, beverages, pharmaceuticals, biological products, daily necessities, drinking water, industrial wastewater, inspection of bacteria in clinical specimens, health and epidemic prevention stations at all levels, environment monitoring stations, food hygiene supervision and inspection institutes, biological products institutes, drug inspection institutes, food factories, daily chemical plants and Universities & colleges, R & D institutions
Steps
1. Turn on the power supply, toggle the switch, the light in the counting pool is on, and the display screen shows "000". Insert the probe pen plug into the instrument jack, and press the "reset" button to zero to make the instrument enter the working state.
2. Put in the culture dish to be inspected
3. Use a probe pen to count all colonies one by one on the bottom of the culture dish, and each point should hear a "beep" to indicate that it is effective, otherwise it should be focused
4. Check carefully with magnifying glass to confirm that there is no omission of points
5. The number in the display screen is the number of colonies in the culture dish
6. After recording the numbers, take out the culture dish, press the "reset" button, and the display screen enters the initial state
Notice
• When the number of colonies in the culture dish exceeds 999, the inspection samples should be diluted to ensure the accuracy of counting
• At each point a colony should hear a "beep" to indicate that it is effective, otherwise it should be focused
• After counting, carefully check with magnifying glass to confirm that there is no omission of points
• After recording the number, press the "reset" button in time to return the display screen to its original state
