Laboratory equipment commonly used, ultrasonic cleaning machineDate: 2022-09-15Number: 244
Ultrasonic cleaning machine is commonly used in the laboratory equipment, its principle is simply that the use of ultrasound to clean objects and appliances.
1. About the material and function of ultrasonic cleaning machine: most of the cleaning machine is made of aluminum or stainless steel material, which makes the overall ultrasonic cleaning machine durable, long life. Some ultrasonic cleaning machines have a drain that helps drain the solution after cleaning, but only some of these features are available on the machine.
Cleaning mechanism: as soon as the ultrasonic cleaner's power cord is plugged in and the machine is turned on, the transducer begins to change size almost immediately. It then converts electrical energy into ultrasonic energy. Due to excitation, the size of the transducer increases, generating high-frequency compressed sound waves and causing the rapid formation and rupture of cavitation bubbles.
As the compression wave continues, the cavitation bubbles become larger and larger, and when they reach a certain size and can no longer maintain their shape, the bubbles stir in the liquid, separating it. These bubbles can hit objects in the tank, causing dust, dirt, bacteria, oil, paint and other contaminants that may stick to the object to fall off. The same thing happens when you put a portable ultrasound machine in a sink or bowl of water.
Ultrasonic cleaning machine frequency: ultrasonic frequency in thousands of cycles per second as a unit of measurement, it is one of the factors that determine the size of cavitation bubble. The high frequency produces small bubbles that provide a gentle cleaning effect.
Low frequencies, on the other hand, produce larger bubbles, which collapse inward in a very sudden and violent manner. It is difficult to visually distinguish the size of the bubbles.
This means that if you want to remove dirt and other contaminants from durable items, you need to use a low-frequency ultrasonic cleaner. However, if you want to clean and clean delicate and soft objects such as jewelry and food, you need to use more frequent ultrasonic cleaners.
They are also the perfect cleanser for items in narrow areas. But a frequency of 40 kHz is usually appropriate for most applications. Whether you want to grow or need a portable ultrasound machine, if you want to clean a variety of objects, please consider using dual-frequency ultrasonic cleaner.
