What factors should be considered when purchasing ultrasonic stirring equipment?

Ultrasonic stirring equipment is a device that uses ultrasonic technology to achieve efficient mixing. The working principle is based on the cavitation effect generated by ultrasonic waves in liquids. When ultrasonic waves propagate in liquids, they form alternating high-pressure and low-pressure areas, causing tiny bubbles to form and rupture rapidly, releasing powerful energy, generating local high temperature and high pressure, and strong fluid dynamic shear force, so that liquids of different components are evenly mixed.

The following are some key factors that need to be considered when purchasing ultrasonic stirring equipment. Let's take a look together.
1. Power and frequency
Power and frequency are key parameters that determine the effect of ultrasonic stirring. Different application scenarios have different specific requirements for the two. Generally speaking, higher power means stronger stirring ability, which is suitable for processing larger volumes or materials that are difficult to mix. The frequency affects the size of cavitation bubbles and the local high-temperature and high-pressure environment generated when they rupture. Under normal circumstances, lower frequencies (such as 20 kHz) can produce greater cavitation effects and are suitable for strong stirring; higher frequencies (such as above 40 kHz) are more suitable for delicate operations.
2. Capacity and size
Choose the appropriate size of ultrasonic stirring equipment according to the actual capacity of the sample to be processed. If you are dealing with small samples, you do not need to choose oversized equipment, which will not only waste resources but also affect accuracy. On the contrary, if you need to deal with large quantities of materials, you should choose a model with a larger capacity to meet the needs. At the same time, you also need to consider the space limitations of the laboratory or production workshop to ensure that the selected equipment can be reasonably placed.
3. Control system
The control system can provide a more accurate operating experience. It should have an easy-to-use interface and support programming functions, allowing users to set parameters such as working mode, time, temperature, etc., and it can automatically adjust the output power throughout the process to maintain constant conditions. In addition, equipment with memory function allows users to save commonly used settings and improve work efficiency.
4. Material quality
Since ultrasonic stirring may be exposed to various chemicals, the choice of equipment material is very important. High-quality stainless steel or titanium alloy probes have good corrosion resistance and durability and are suitable for stirring most chemicals. In addition, the outer shell should also be made of sturdy and easy-to-clean materials for daily maintenance.
5. Safety features
High-quality equipment should be equipped with a variety of safety measures, such as overload protection and short-circuit protection, to prevent equipment damage or personal injury caused by improper operation. Some models may also be integrated with emergency stop buttons and fault alarm systems, further improving the safety of use.

In summary, when purchasing ultrasonic stirring equipment, it is necessary to comprehensively consider multiple factors such as power frequency, capacity size, control system, material quality and safety characteristics, and make a choice based on your specific needs. This will not only ensure the smooth progress of experiments or production but also effectively extend the service life and reduce cost investment.
