How to choose an ultrasonic cell disruptor

The ultrasonic cell disruptor consists of two parts: an ultrasonic generator and a transducer (some are equipped with a soundproof box):

1. 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.

2. Transducer assembly: The transducer assembly is mainly composed of a transducer and an horn.

3. Soundproof box: It can effectively reduce the noise emitted during work and keep the laboratory quiet.

The promotion of the ultrasonic cell disrupter in the industry in our country has entered a mature stage, but the application is still not popular enough! This instrument (equipment) has a very wide range of applications, which is unmatched by other instruments. It is precisely because of this that the market potential of this instrument (equipment) is great, so the number of manufacturers is increasing. This has also caused relative chaos in the ultrasonic cleaning industry and the market. You can use eight words to describe "a mix of good and bad, good and bad"! Classify the ultrasonic cell disruptor.

The specific divisions are as follows:

1. Classified by power

The power of the ultrasonic cell disruptor is the first choice of the customer, it determines the quantity, size, quality and effect of the broken objects. Therefore, the manufacturers also attach great importance to this indicator. Under normal circumstances, laboratories, laboratories, research institutes, drug inspection institutes and other scientific research units use low power (generally below 500W); while biological companies, pharmaceutical factories, chemical companies and other production units use power Most of them are around 500W-2000W. As the product structure of each manufacturer is different, the marking method of its power is also different. However, according to the common practice of users, there are generally the following types: 50W, 100W, 150W, 250W, 300W, 350W, 500W, 1000W, 2000W. Generally, the output power of the ultrasonic cell disruptor can be adjusted appropriately according to the needs. The rated operating frequency of the standard ultrasonic cell pulverizer product is 20 kHz. Some ultrasonic cell pulverizers have an auto-tuning function to make the frequency change within a small range.

2. Classified by the diameter of the probe ("tip")

It is necessary to select ultrasonic disruptors with different "Tip" heads to process samples with different volumes. Due to the different product structures of various manufacturers, their "Tip" head diameters are not the same. Generally, "tip" heads range from 5mm (suitable for 1ml processing volume) to 25mm (suitable for 1000ml processing volume), with continuous flow probes, and the processing volume can reach 80 liters/hour. Replaceable "Tip" heads are used in high-energy applications where wear may occur. When energy is transferred through the "Tip" head, corrosion will occur where traces are left on the metal surface. Over time, slight corrosion spots will appear where corrosion occurs. The "Tip" head can be polished with sandpaper or gauze unless it is damaged to a certain degree; when this happens, the "Tip" head will be difficult to tune the frequency. Instead, it may make a long and sharp noise. Cracks occur. To effectively process a given dose of samples, there are two main factors that need to be considered: "Tip" head size and output power. These two factors must be matched at the same time to get the best results. Small power and large "Tip" head, "Tip" head can not work; and too much power, "Tip" head may be damaged. Please pay attention to the required model accessories when purchasing.
