ULTRASONIC HOMOGENIZER

Brief Introduction

Ultrasonic cell pulverizer is a multifunctional and versatile instrument for ultrasonic treatment of substances by using strong ultrasound in liquid. It can be used for the breakup of plant tissue, cell, bacteria and bacillus, and can be used for emulsification, separation, dispersion, homogenization, extraction, degassing, cleaning and acceleration. Chemical reactions and so on. The machine is widely used in the teaching, research and production of Biochemistry, microbiology, medicine chemistry, surface chemistry, physics, zoology, agriculture, medicine, medicine and so on.

With the development of the biological industry, the application of ultrasonic cell mill has also been improved, such as the measurement and control of sample temperature, the improvement of the low temperature cooling sample and the improvement of the whole machine's intelligentization degree, and so on, the new requirement [1] is put forward.

Basic Principle

Ultrasonic cell pulverizer is the use of ultrasonic wave in the liquid dispersion effect, make the liquid produce cavitation, so that the solid particles in the liquid or cell tissue broken. Ultrasonic cell mill consists of two parts of ultrasonic generator and transducer. The ultrasonic generator turns the electricity into 18-21KHz alternating current power supply transducer. The barium zirconate titanate piezoelectric oscillator is the heart of the transducer. It deforms elastically at 18-21KHz with alternating voltage, and the transducer vibrates longitudinally. Vibration wave produces cavitation effect by immersing titanium alloy horn in biological solution, and excites the violent vibration of biological particles in the medium.

CharacTeristic

1, automatic frequency modulation and vibration, without manual adjustment.

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

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

4, the standard probe can be converted downwards through MICROTIP under 1/2 "to achieve the fragmentation of micro samples.

5, there are sealed cups (CUP) and continuous flow (FILLCELL) and other different styles of probe for purchase.

6, there are 96 holes of enzyme plate broken head and double needle probe (to ensure experimental parallelism) probe for purchase.

7, the actual effective power of the output is tracked.

8, there are nine program memory functions to facilitate user programming and invocation.

9, we can adjust the "work / intermittence" proportional time cycle pulse work, and the time range is from 0.5 seconds to 1.

Hours, improve crushing effect and effectively prevent temperature rise.

10, there is a question menu to protect micro probes, which can effectively prevent misoperation from damaging the machine [1].

Purpose

Ultrasonic grinder can be used to crush animal and plant cells, bacteria, dental spore or tissues. Scattered rare earth and all kinds of inorganic mineral powder.

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

The ultrasonic pulverizer can make up the one percent size emulsion of near micron; homogenize the "hard to miscible" mixture; polymerize some substances and precipitate some other substances.

In a word, ultrasonic pulverizer can achieve the functions of extraction, crushing, emulsification, homogenization, suspension, variation, gas suspension, accelerated dissolving, crystallization and the preparation of various biological samples under the electron microscope.

Be Careful

1, remember the empty super. This is very important. There is a case in which the ultrasonic breakers are not inserted in the sample. After a few seconds, the ultrasonic breakers make a bigger noise in the future. Remember that the longer the ultrasonic breaker is, the longer the time is, the greater the damage to the instrument.

2. The depth of the horn (ultrasonic probe) of ultrasonic crusher entering water is about 1.5 cm. The liquid level should be above 30 mm. The probe should be in the middle and not stick to the wall. Ultrasonic is vertical longitudinal wave, too deep insertion is not easy to form convection, affecting crushing efficiency.

3, ultrasonic crushing parameter equipment: this point, please be sure to refer to the use of the instructions, set up the key parameters of the instrument, mainly time parameters, ultrasonic power parameters, and the selection of containers.

Time requirements: ultrasonic time can not be over time, it is better not more than 5 seconds, gap time should be greater than or equal to the ultrasonic time, so it is good for heat emission.

Power requirements: not too large, too common to spatter or foam. Container selection: The size of the beaker should be as large as the number of samples. This is also helpful for the sample convection in ultrasound to improve the crushing efficiency.

4, after routine maintenance, use alcohol to wipe the probe or use water to carry out ultrasonic [1] after use.
