Generally, ultrasonic welding machines have few functions and are not accurate in terms of speed and capacity. Such ultrasonic welding machines are only suitable for general centrifugal operations. The speed and capacity are accurate and suitable for some tests that require higher requirements for ultrasonic welding machines. According to the size of the workload, it is mainly selected from two aspects: speed and capacity. The following specifically introduces the issues that should be paid attention to when purchasing a fine ultrasonic welding machine:

1. Capacity: The ultrasonic welding machine prompts how many sample tubes need to be centrifuged each time, and how much capacity each sample tube needs. These factors determine the total capacity of an ultrasonic welding machine. In short, the total volume of the ultrasonic welding machine.

2. Rotation speed: Ultrasonic welding machines are divided into low-speed ultrasonic welding machines, high-speed ultrasonic welding machines, and high-speed ultrasonic welding machines according to the different speeds. Each ultrasonic welding machine has an additional speed. The speed refers to the speed under no-load conditions. , But the speed varies depending on the rotor type and the size of the sample quality. Different rotors have different speeds. Horizontal rotors can reach 15000 rpm/min, but angular rotors can reach 14000 rpm/min. For specific differences, please consult the product salesperson and the relevant technical personnel of the manufacturer. Therefore, in the selection of the speed To be stable, the speed of the selected ultrasonic welding machine should be higher than the target speed.

3. Temperature: Some samples will be damaged in a high temperature environment, so we need to choose a frozen ultrasonic welding machine, which has an additional temperature scale. When the ultrasonic welding machine is working at high speed, the heat generated and the refrigeration system of the ultrasonic welding machine are balanced at a certain temperature. The specific reach is also related to the rotor. This point should also be consulted with product sales personnel and relevant technical personnel of the production plant.

The above are the matters needing attention when buying an ultrasonic welding machine, and everyone must pay attention to it when buying.
