Now with the advancement of technology, the colony counting technology is getting better and better. Mainly reflected in the configuration is getting higher and higher, the function is more and more complete. The counting speed is getting faster and faster, and the accuracy is getting higher and higher. Therefore, the price will rise.
Generally, for users with less precise requirements, manual or semi-automatic colony counters can be considered. Manual price is relatively cheap, the market price is about 800-1200 yuan, slightly better, is semi-automatic with voice reading function, the magnification is above 3, the market price is about 2500 yuan, this has been Can meet the counting requirements of most users. The high-profile automatic counter is used in the microbiology laboratory. The main pixels are 3 million, 9 million and 10 million. A lot of analysis functions have been added to the software, and the price is also between 30,000 and 80,000. The imported colony counters are mainly from three countries, Germany, the United Kingdom and France. For semi-automatic instruments of the same function, the price difference between domestic and imported is about 2-3 times. The fully automatic price is also more than doubled. Demanders should consider their own needs and budget to purchase.
Instructions
1. Plug the power plug into the 220V power socket. Insert the probe into the probe socket on the instrument.
2. Turn the power switch to the on and the light in the counting pool is on. At the same time, the display window is bright, indicating that counting is allowed.
3. Place the bottom of the culture dish to be tested upward into the counting cell. Use a probe to count all the colonies on the bottom of the dish. At this time, the colony is marked with a color, and the numbers in the display window are automatically accumulated.
4. Check carefully with a magnifying glass to confirm that the points are not missing, and the counting is completed.
5. The number in the display window is the number of colonies in the dish.
6. Remove the culture dish after recording the numbers. Press the reset button to display the recovery and prepare for the counting of another dish.
Precautions
1. Plug the power plug into the 220V power socket. Insert the probe into the probe socket on the instrument. 2. Turn the power switch to "ON" and the indicator light in the counting pool is on. At the same time, the display shows a bright "0000", indicating that the counting is allowed. If the number is opened for the second time, the last count is not cleared. 3. Place the bottom of the culture dish to be tested upward into the counting cell. Use a probe to count all the colonies on the bottom of the dish. At this time, the colony is marked with a color, and the numbers in the display window are automatically accumulated. 4. Check carefully with a magnifying glass to confirm that the points are not missing, and the counting is completed. 5. The number in the display window is the number of colonies in the dish. 6. Remove the culture dish after recording the numbers. Press the "clear" button to display the recovery "0000" and prepare for the counting of another dish.
