1, remember the air super. This is very important, there is such a case, in the absence of the ultrasonic crusher to insert the horn into the sample of the start of the air super, empty after a few seconds, after the ultrasonic crusher in the use of the process of noise becomes larger. Remember to the ultrasonic Crusher Air Super, the longer the time, the greater the damage to the instrument.
2, ultrasonic crusher horn (ultrasonic probe) into the water depth: 1.5Cm or so, the height of the liquid surface preferably 30mm above, the probe to center, do not paste wall. Ultrasonic is vertical longitudinal wave, inserting too deep is not easy to form convection, affecting the crushing efficiency.
3, Ultrasonic crushing parameter equipment: This point please be sure to refer to the use of instructions, set the key instrument working parameters, mainly time parameters, ultrasonic power parameters, as well as the choice of containers.
Time Requirements: Ultrasound time can not be too long time, preferably not more than 5 seconds, clearance time should be greater than or equal to the ultrasound time, so that the heat distribution is beneficial.
Power requirements: Not too large, too assembly to make the sample splash or foam. Container selection: How much of the sample before the size of the beaker, which is also beneficial to the sample in the ultrasonic convection, improve the crushing efficiency.
4, the daily maintenance, use alcohol to scrub the probe or use water for ultrasound.
