Using steps of ultrasonic cell breaker:
1. Put the transducer connected with the horn into the special jack on the top of the sound isolating box, and then connect the power line to the power input interface behind the host; And connect the host power cord.
2. Set "ultrasonic time, gap time and working times". Generally, the ultrasonic time should not be too long, and should be controlled within 1-5 seconds. When working, the gap time should be greater than the working time for experiments.
3. Select appropriate containers (test tubes, beakers and centrifuge tubes) according to the sample volume. After fixing, adjust the lifting table in the sound insulation box to determine the high and low position, so that the end of the horn is inserted into the sample liquid level 1-1.5cm and placed in the center of the container, and the horn is not allowed to contact the container wall; The distance between the end of the luffing rod and the container should generally be greater than 30mm. When the measurement is small, the distance can be greater than 10mm (depending on the container).
4. After power on, the power indicator light is on, and then press the protection reset button and work reset button again.
The good or bad use of the ultrasonic crusher will be directly reflected in its service life. Therefore, in the daily use process, the operator must pay attention to some matters to prevent the failure of the instrument and affect the normal use. In addition to paying attention to use, maintenance is also very important. Now let's focus on the precautions when using the ultrasonic cell crusher of Jiangsu Tianling Instrument Co., Ltd.:
1. It is strictly forbidden to start the machine when the horn of the ultrasonic crusher is not inserted into the liquid (empty), otherwise the transducer or ultrasonic generator will be damaged.
2. The amount of broken cells, the length of time and the size of power need to be determined by the user according to different cells, and the value should be selected.
3. The ultrasonic crusher adopts switching power supply without power frequency transformer. Do not touch it randomly after opening the generator shell to prevent electric shock. This instrument has reliable performance and is generally not easy to be damaged.
4. During ultrasonic crushing, the temperature of the liquid will rise quickly due to the cavitation effect of ultrasonic in the liquid. It is recommended to use multiple crushing in a short time (no more than 5 seconds each time), and at the same time, add ice bath for cooling or select our low-temperature circulating pump.
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. If the horn inserted into the liquid level is deep and the load concentration is large, the displayed value may be slightly smaller, and vice versa.
6. The effect of working for many times in a short time is better than that of working for a long time continuously. In order to prevent the liquid from heating, a longer gap time can be set. Working for a long time without interruption is easy to form no-load and shorten the service life of the ultrasonic crusher.
