6 precautions for the use of ultrasonic cell disrupter

Whether the ultrasonic cell disruptor is used well or not will be directly reflected in its lifespan. Therefore, in the daily use process, the operator must pay attention to some matters to prevent the instrument from malfunctioning and affecting normal use. In addition to paying attention to use, maintenance is also very important. Let's focus on the points that should be paid attention to when using:

　　

1. It is strictly forbidden to turn on the ultrasonic cell disrupter when the horn of the ultrasonic cell disrupter is not inserted into the liquid (no load), otherwise it will damage the transducer or ultrasonic generator.

　　

2. The amount of crushing of various cells, the length of time, and the size of power are to be determined by the user according to various cells and select the best value.

　　

3. The ultrasonic cell disruptor adopts a switching power supply without a power frequency transformer. Don't touch it after opening the generator casing to prevent electric shock. This instrument has reliable performance and is generally not easily damaged.

　　

4. During ultrasonic crushing, due to the cavitation effect of ultrasound in the liquid, the temperature of the liquid will rise quickly. It is recommended to use multiple crushing in a short time (not more than 5 seconds each time), and ice can be added at the same time. Bath cooling or optional low temperature circulating pump of our company.

　　

5. The value displayed by the power meter is related to the voltage, the depth of the horn inserted into the liquid level, and the load is related to the concentration and consistency of the broken sample. The horn is inserted deeper into the liquid level and the load concentration is larger. The displayed value may be Slightly smaller, and vice versa.

　　

6. Short-time multiple work is better than continuous long-time work. In order to prevent the liquid from heating up, a longer gap time can be set. Uninterrupted long-term work is easy to form no-load and shortens the ultrasonic pulverizer Service life.
