Shanghai Bilang Ultrasonic Cell Crusher (Ultrasonic Cell Breaker) consists of two parts: an ultrasonic generator and a transducer (some are equipped with soundproof boxes). Ultrasonic generator: Working principle: The signal generator generates a signal of a specific frequency. This specific frequency is the frequency of the transducer. The ultrasonic frequencies generally used in ultrasonic equipment are 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz . Transducer assembly: The transducer assembly is mainly composed of a transducer and a horn. Soundproof box: can effectively reduce the noise emitted during the work and keep the laboratory quiet.
Here, pay special attention to the ultrasonic cell breaker. The ultrasonic cell crusher will cause great damage to the instrument under the condition of air overload. If the time is too long, the ultrasonic cell crusher will be damaged and cannot be used normally. For example, when the horn of the ultrasonic breaker is inserted into the sample, it starts to run empty. After a few seconds of emptying, the ultrasonic breaker will become louder in the future. Remember to overtake the ultrasonic breaker, the longer the overtime, the greater the damage to the instrument.
Time requirements: The ultrasonic time should not be too long each time, preferably not more than 5 seconds, and the gap time should be greater than or equal to the ultrasonic time, which is beneficial to heat dissipation. Power requirements: It should not be too large, too large will cause the sample to splash or foam. Container selection: As many samples as possible, the beaker is the first, which is also conducive to convection of the sample in ultrasound and improves the crushing efficiency. In daily maintenance, scrub the probe with alcohol or perform ultrasound with clean water after use
The promotion of ultrasonic cell disruption instrument in China's industry has entered a mature stage. The instrument (equipment) has a wide range of applications. Go to Shanghai Bilang for more details!
