Shanghai Haozhuang Instrument Co., Ltd. developed the LNB brand ultrasonic cell shredder, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable
Precautions for use of ultrasonic cell crusher: 1. The temperature protection set point must be higher than room temperature or the sample temperature by more than 5 ℃. When temperature protection occurs, press SET key for more than 4 seconds to reset the protection value. When setting the wrong temperature, you can also press the SET button for more than 4 seconds to reset. 2. It is strictly forbidden to start when the horn is not inserted into the liquid (no load), otherwise it will damage the transducer or ultrasonic generator. 3. The amount of broken cells, the length of time, and the size of the power are waiting for the user to explore and determine the best value according to various cells. The output power of this instrument is relatively large. If the Ф2, Ф3 or Ф6 horn is selected, the power should be turned down to prevent the horn from overloading and breaking. Amplifier power usage range Amplifier specification power range around Φ2 2 ~ 20% Φ3 3 ~ 30% Φ6 10 ~ 50% Φ10> 18% Φ15> 22% Φ20> 30% 4. After a certain period of time, the end of the horn It will be corroded and corroded, and it can be flattened with oil stone or file, otherwise it will affect the work effect. 5. Use of the horn selection switch The horn selection switch is used to match the frequency and impedance consistency of the horn and generator of different specifications. If the frequency of the transducer assembly is inconsistent with the impedance of the generator, the ultrasound will not work. When a new instrument or a new horn is equipped, the selector switch should be in the corresponding position. When the horn is worn, the switch can be toggled until the ultrasound works normally. At this time, the gear position does not necessarily correspond to the specifications of the horn. The horn selection switch of the ultrasonic cell crusher is usually placed at the position corresponding to the horn when it is shipped from the factory. When the horn is worn, the user can freely select the gear until the ultrasound works normally. Rod specifications do not necessarily correspond. 6. No preheating is required, and good grounding should be used. 7. During ultrasonic breaking, due to the cavitation effect of ultrasonic waves in the liquid, the temperature of the liquid will quickly rise, and users should pay more attention to the temperature of various cells. It is recommended to use multiple crushing in a short time (no more than 5 seconds each time), and an ice bath can be used for cooling. 8. The ultrasonic cell crusher uses a switching power supply without a power frequency transformer. Do not touch it randomly after opening the generator casing to prevent electric shock. This instrument has reliable performance and is generally not easily damaged. 9. The ultrasonic cell pulverizer should be placed in a dry place without moisture, direct sunlight, or corrosive gas. 10. Practice shows that: multiple work in a short time, working time 1-2 seconds, gap time 1-2 seconds, better than continuous long-term work. To prevent the liquid from heating up, a longer gap time can be set. In addition, uninterrupted long-term work is easy to form a no-load, shortening the service life of the instrument.
