The Composition of the Ultrasonic Homogenizer

The ultrasonic cell homogenizer utilizes the cavitation effect of ultrasonic waves in a liquid to cause cavitation of the liquid, thereby breaking solid particles or cell tissues in the liquid. The conventional method is to put the material to be broken into a beaker, turn on the power setting time (vibration time and intermittent time), and put the tip into the material. During use, the ultrasonic generator circuit converts the 50/60 Hz mains into 18-21 KHz high-frequency high-voltage electric energy. Therefore, a large amount of heat is generated during the crushing process, which is generally broken under an ice bath.

The ultrasonic cell homogenizer consists of three parts: an ultrasonic generator, a transducer and each speaker. The working principle of the ultrasonic generator is to generate a signal of a specific frequency by the signal generator. This specific frequency is the frequency of the transducer. The ultrasonic frequency generally used in the ultrasonic device is 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz. . The transducer assembly consists primarily of a transducer and a horn. The soundproof box can effectively reduce the noise generated during the work and keep the laboratory quiet.

Ultrasonic cell homogenizer has been widely used in the fields of biology, microbiology, physics, zoology, agronomy, and pharmaceuticals. How to choose ultrasonic homogenizer is based on its power and crushing capacity, and at the same time matches the corresponding ultrasonic probe. Ultrasonic power is the preferred indicator of choice, which determines the quantity, size, quality and effectiveness of the sample. Under normal circumstances, laboratories, laboratories, research institutes, drug testing institutes and other scientific research units use little power; while bio-companies, pharmaceutical factories, chemical companies and other production units use about 500W-2000W.

To handle different volume samples, you need to choose a different "tip" ultrasonic breaker. The general "tip" is from a trace of 2mm (suitable for 0.5ml throughput) to 28mm (suitable for 1200ml throughput. Replaceable "tip" is used in high-energy applications where wear can occur. When energy is transferred through the "tip", the metal Corrosion can occur where the surface leaves traces. Over time, there will be slight pitting on the place where corrosion occurs. The “tip” can be sanded with gauze or gauze unless it is damaged to a certain extent; When the situation occurs, the “tip” will be difficult to tune the frequency, instead it will emit long, sharp noise and eventually crack. To effectively process a given dose of the sample, there are two main factors to consider: “tip” size and output power. These two factors must be matched at the same time to get the best results. If small power, but big "tip", then "tip" can not work; too big power "tip" may be damaged.
