1. Ultrasonic cleaning machine
Ultrasonic waves can produce powerful physical effects, such as ultrasonic radiation, ultrasonic cavitation and ultrasonic microflow, which can effectively clean samples. Therefore, ultrasonic cleaning machines are widely used in laboratories, and the items to be cleaned can be metal utensils, plastics and other materials, and biological samples. The main principle of ultrasonic cleaning machines is that the high-pressure alternating waves generated by ultrasonic oscillation in water cause the bubbles in the water to oscillate violently, generating a large number of small bubbles, thereby forming a high-pressure and high-temperature area, loosening sediments and dirt, and generating impact force to quickly remove substances from the surface.
2. Ultrasonic cell disruptor
Ultrasonic cell disruptor is an instrument commonly used in biology, biomedicine, food science and other fields, which can be used for cell crushing, pulverization and ultrasonic dispersion. Due to the large elasticity of the cell membrane, the crushing of cells requires the use of strong physical force. Ultrasonic waves can vibrate at high frequencies, generate strong mechanical shear force and separation force, and then rupture the cell membrane and release the substances in the cell.
The instruments used for ultrasonic processing in the laboratory are mainly the following:
Ultrasonic oscillator: It is mainly composed of a generator, a transducer and an oscillation tube, and is mainly used for the cracking, dispersion, emulsification and other treatments of compounds.
Ultrasonic cleaning machine: It is mainly used to clean experimental utensils and experimental tools, and can help remove difficult-to-clean substances attached to the utensils.
Ultrasonic emulsifier: It is mainly used in emulsification, dispersion, mixing, etc., and is suitable for the preparation of particles, colloid emulsification, and suspensions. It is particularly suitable for the emulsification of surfactants and polymer compounds.
Homogenizer: It is an instrument that uses ultrasonic waves to convert into mechanical vibrations to make the sample vibrate to achieve homogenization, crushing and mixing. It is mainly used in the fields of cell rupture, digestion of viruses, microorganisms and plant cells.
Ultrasonic thawing instrument: It is used to thaw samples with water, and is suitable for experiments that require fast operation. The above instruments are all common ultrasonic processing equipment in laboratories. The specific instrument to be used depends on the specific needs of the experiment.
