The purpose and use points of ultrasonic cell crusher
Ultrasonic cell pulverizer is a commonly used pulverizer product, which uses the dispersion effect of ultrasonic waves in the liquid to produce cavitation in the liquid, thereby breaking the solid particles or cell tissue in the liquid. Today we mainly introduce the use and principle of ultrasonic cell crusher, hoping to help users better apply products.
Use of ultrasonic cell crusher:
The ultrasonic pulverizer can be used to pulverize animal and plant cells, bacteria, dental spores or tissues. Disperse rare earth and various inorganic mineral powders.
Ultrasonic pulverizer is an ideal device to accelerate the reaction speed of chemistry, biology and physics and accelerate the degassing of liquid.
Ultrasonic pulverizer can prepare latex with a size of nearly one-hundredth of a micron; homogenize the "immiscible" mixed liquid; polymerize some substances and precipitate other substances.
In short, the ultrasonic pulverizer can achieve multiple functions of extraction, pulverization, emulsification, homogenization, suspension, variation, air suspension, accelerated desolvation, crystallization, and preparation of various biological samples under an electron microscope.
Key points of using ultrasonic cell crusher:
1. Remember empty super. This is very important. There is a case where the ultrasonic breaker was turned on without inserting the horn of the ultrasonic breaker into the sample. After a few seconds of clearance, the ultrasonic breaker became louder during subsequent use. Remember to supersede the ultrasonic breaker, the longer the supersonic time, the greater the damage to the instrument.
2. The penetration depth of the horn (ultrasonic probe) of the ultrasonic breaker: about 1.5cm, the height of the liquid level is above 30mm, and the probe should be centered and not attached to the wall. Ultrasound is a vertical longitudinal wave, it is not easy to form convection if inserted too deep, which affects the crushing efficiency.
3. Ultrasonic crushing parameter equipment: For this, please refer to the instruction manual and set the working parameters of the instrument, mainly time parameters, ultrasonic power parameters, and container selection.
Time requirements: The ultrasound time should not be too long each time, not more than 5 seconds, and the gap time should be greater than or equal to the ultrasound time, which is good for heat dissipation.
Power requirements: not too large, too large will cause the sample to splash or foam. Container selection: the size of the beaker is as large as there are samples, which is also beneficial to the convection of the sample under ultrasound and improves the crushing efficiency.
4. In daily maintenance, scrub the probe with alcohol or ultrasound with clean water after use.
