Ultrasonic cell crusher is a kind of important equipment used in biological laboratories, and its main function is to crush biological samples quickly and effectively. This equipment breaks the samples through high-frequency oscillation of ultrasonic waves, which has the advantages of easy operation, high crushing efficiency and little damage to the samples. Therefore, it has been widely used in biology, medicine, pharmaceuticals and other fields. In this article, we will learn about the working principle of the ultrasonic cell crusher and the precautions to be taken when using it.

What is Ultrasonic Cell Disruptor

Ultrasonic Cell Disruptor is a multi-functional, multi-purpose instrument that utilizes an ultrasonic wave to produce cavitation effect in liquid. It can be used to break various animal and plant cells, virus cells, bacteria and tissues, and can also be used to break and reorganize various inorganic substances. It is suitable for teaching, scientific research and production in the fields of biochemistry, microbiology, pharmacology, zoology, medicine and pharmacy.

Working Principle of Ultrasonic Cell Disruptor

The working principle of Ultrasonic Cell Disruptor mainly relies on the cavitation effect of ultrasonic waves in liquid. Ultrasonic Cell Disruptor converts electrical energy into acoustic energy through a transducer, and this energy is transformed into a dense bubble through the liquid medium. These small bubbles quickly explode, generating energy similar to a small bomb, thus playing a role in breaking cells and other substances.

Composition of ultrasonic cell crusher

By the ultrasonic generator and transducer two major components (some configurations have soundproof box).
1. Ultrasonic generator
By the signal generator to produce a specific frequency signal, this specific frequency is the frequency of the transducer. Generally used in ultrasonic equipment in the ultrasonic frequency of 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz.
2. Transducer components
The transducer assembly mainly consists of transducer and amplifier rod.
3. Soundproof box
It can effectively reduce the noise during the working process and keep the laboratory quiet.

Ultrasonic cell crusher use precautions

  1. The ultrasonic cell crusher should be placed in a clean and dry place, and should not be placed in damp, high temperature, dusty and corrosive gas place;
  2. Ultrasonic cell crusher on the back panel of the amplitude lever selector switch should be in the corresponding position of the amplitude lever, the new amplitude lever should correspond to the selector switch;
  3. Container capacity and shape of the choice and the sample of the pair of less coordinated, the use of slender description of the device crushing effect is better;
  4. It is recommended to use a short time multiple crushing, ultrasonic time within 5 seconds, the interval time is less than 5 seconds;
  5. The transducer in the bracket should be fixed firmly to prevent slipping from the upright.
