A defoaming machine is a commonly used laboratory equipment designed to remove bubbles from liquids. Mastering the correct techniques and precautions for using a defoaming machine is crucial for students and researchers during experiments and research. This article will introduce some essential tips and precautions for using a defoaming machine.

Firstly, correct operation of the defoaming machine is crucial. Before using the defoaming machine, it needs to be connected to the vacuum pump, ensuring a tight connection to prevent gas leakage. Next, pour the liquid to be defoamed into the defoaming machine, making sure not to exceed its maximum capacity. Then, start the vacuum pump and gradually reduce the valve opening to avoid rapid bubble generation. After waiting for a period of time, adjust the valve opening of the vacuum pump appropriately to control the defoaming speed and effectiveness. Finally, when all the bubbles in the liquid are completely removed, the vacuum pump can be turned off, and the defoamed liquid can be removed from the machine.

Secondly, safety precautions must be observed when using the defoaming machine. Wear laboratory safety equipment such as lab coats, gloves, and goggles during operation. Adhere to laboratory safety regulations, ensuring that the workbench is clean and tidy to avoid accidents. Also, avoid placing toxic or flammable substances in the defoaming machine to prevent hazards.

Additionally, understanding the principles and operation details of the defoaming machine is essential for students and researchers. The principle of the defoaming machine relies on the negative pressure generated by the vacuum pump to remove bubbles from the liquid. Therefore, it is necessary to understand the working principle and usage of the vacuum pump before using the defoaming machine. Additionally, familiarize oneself with the different components of the defoaming machine and the functions of the control switches for correct operation and adjustment.

Finally, students and researchers should pay attention to the routine maintenance of the defoaming machine. Regularly inspect and clean all components of the defoaming machine to ensure its normal operation. During use, promptly replace damaged parts to avoid affecting the effectiveness and lifespan of the defoaming machine.

In conclusion, students and researchers need to master the correct operation techniques and precautions when using a defoaming machine in experiments and research. By operating the defoaming machine correctly, observing safety measures, and performing regular maintenance, the efficiency and accuracy of experiments and research can be improved. It is hoped that this article will be helpful to everyone, and best wishes for success in experiments and research!
