Ultrasonic cell crusher

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

Briefly

Ultrasonic cell crusher is a multi-functional and multi-purpose instrument that uses strong ultrasound 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 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 ultrasonic cell pulverizers have also increased, such as the measurement and control of sample temperature, the improvement of low-temperature cooling samples and the improvement of the intelligence of the whole machine, etc., all of which have put forward new requirements. .

Fundamental

The ultrasonic cell pulverizer uses the dispersion effect of ultrasonic waves in the liquid to cause cavitation in the liquid, thereby breaking the solid particles or cell tissue in the liquid. Ultrasonic cell crusher is composed of ultrasonic generator and transducer. 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

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 through 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.

use

Ultrasonic pulverizers can be used to pulverize animal and plant cells, bacteria, dental spores or tissues. Disperse rare earth and various inorganic mineral powders.

Ultrasonic mill is an ideal device to accelerate the reaction speed of chemistry, biology, physics and accelerate the degassing of liquids.

The ultrasonic pulverizer can prepare emulsions with a size of nearly 1% of microns; homogenize "immiscible" mixtures; polymerize some substances and separate out other substances.

In a word, ultrasonic pulverizer can realize multiple functions of extraction, pulverization, emulsification, homogenization, suspension, mutation, aerosol, accelerated desolvation, crystallization and preparation of various biological samples under electron microscope.

Notice

1, remember to empty super. This is very important. There is such a case that the air supersonication was started without inserting the horn of the ultrasonic crusher into the sample. After a few seconds of air supercharging, the noise of the ultrasonic crusher became louder during subsequent use. Remember to empty the ultrasonic breaker, the longer the empty ultra, the greater the damage to the instrument.

2. The horn (ultrasonic probe) of the ultrasonic crusher enters the water depth: about 1.5cm, and the liquid level is above 30mm. The probe should be centered and not attached to the wall. Ultrasound is a vertical longitudinal wave, and it is not easy to form convection if it is inserted too deep, which affects the crushing efficiency.

3. Ultrasonic crushing parameter equipment: Please refer to the instruction manual for this point, and set the working parameters of the instrument, mainly the parameters of time, the parameters of ultrasonic power, and the selection of containers.

Time requirements: The ultrasonic time should not be too long each time, not more than 5 seconds, and the interval time should be greater than or equal to the ultrasonic time, which is good for heat dissipation.

Power requirements: should not be too large, too large will cause the sample to splash or foam. Container selection: as many beakers as there are samples, it is also beneficial for the samples to convect in ultrasound and improve the crushing efficiency.

4. In daily maintenance, scrub the probe with alcohol or perform ultrasound with water after use.
