Article source:LAWSON Author:Lawson Popularity: 636 Issuing Time:2020/3/4 9:18:53

The continuous flow ultrasonic pulverizer uses the dispersion effect of ultrasonic waves in the liquid to cavitate the liquid, thereby breaking the solid particles or cell tissue in the liquid.

Continuous flow ultrasonic pulverizer is a multi-functional and multi-purpose instrument that uses strong ultrasonic to produce cavitation effect in liquid and ultrasonically treat substances. It can be used for the crushing of animal and plant tissues, cells, bacteria and spores. At the same time, it can be used to emulsify, separate, disperse, homogenize, extract, degas, clean and accelerate chemical reactions, etc. This machine is widely used in teaching, scientific research and production in the fields of biochemistry, microbiology, medicinal chemistry, surface chemistry, physics, zoology, agronomy, medicine, and pharmaceuticals.

With the development of the biological industry, the experimental requirements for the application of continuous flow ultrasonic pulverizers have also increased. Require.

Basic principle of continuous flow ultrasonic mill:

The continuous flow ultrasonic pulverizer uses the dispersion effect of ultrasonic waves in the liquid to cavitate the liquid, thereby breaking the solid particles or cell tissues in the liquid. The ultrasonic cell pulverizer consists of two parts: an ultrasonic generator and a transducer. composition. The ultrasonic generator converts the mains power into 18-21KHz alternating electric energy to supply the transducer. The barium zirconate titanate piezoelectric vibrator is the heart of the transducer. It stretches and elastically deforms with the alternating voltage at a frequency of 18-21KHz, and the transducer then vibrates longitudinally. The vibration wave produces a cavitation effect through the titanium alloy horn immersed in the biological solution, which excites the biological particles in the medium to vibrate violently.

Features of Continuous Flow Ultrasonic Mill:

1. Automatic frequency modulation to start vibration without manual adjustment.

2. There is a temperature protection probe, which can effectively prevent the sample from being damaged due to temperature rise during the crushing process.

3. According to the feedback signal of the temperature probe, the work of the external temperature control unit can be driven by the "normally open/normally closed" switch.

4. The standard probe below 1/2" can be down-converted through MICROTIP to achieve the crushing of trace samples.

5. There are different styles of probes such as closed cup (CUP) and continuous flow (FILLCELL) for purchase.

6. There are 96-well microplate breaking heads and double-needle probes (to ensure experimental parallelism) probes for purchase.

7. Tracking display output actual effective power.

8. There are nine program memory functions, which are convenient for users to program and call.

9. Adjustable "work/intermittent" proportional time cycle pulse work, the time range is from 0.5 seconds to 1 hour, to improve the crushing effect and effectively prevent temperature rise.

10. There is a question menu to protect the micro probe, which can effectively prevent the machine from being damaged by misoperation.
