How does laboratory ultrasonic cleaner clean the pH electrode?
The pH electrode is a very precise detection element. Its electrode is more than a glass electrode as a measuring electrode. It is used as a glycine electrode as a reference electrode. If the pH electrode is contaminated, its sensitivity will decrease, and the stability also deteriorates. Therefore, it is especially important for the cleaning of the pH electrode. However, there are many cleaning methods used by the pH electrodes. The most original cleaning method is human manual cleaning. But there are many drawbacks to manually cleaning. Therefore, in order to solve this problem, the laboratory ultrasonic cleaner appears. It is very convenient to use a practical laboratory ultrasonic cleaning. But how does the laboratory ultrasonic cleaner cleans the pH electrode?
First, the laboratory ultrasonic cleaner mounts an ultrasonic cleaning head below the pH electrode. An oscillation source of the average frequency is provided from the laboratory ultrasonic cleaner to the cleaning head. Thereby the cleaning head produces high-frequency vibration. The high-frequency vibration of the cleaning head is transmitted to the measured solution. An air gap is generated in the solution and immediately disappears. The air gap is repeated and disappeared vaporization effects can cause fouling of the electrode sensitive portion or prevent contaminants from adhering.
Second, the laboratory ultrasonic cleaner has the latest ultrasonic cleaning transducer. The sound wave cleaning is performed on the circuit void of the pH motor using ultrasonic waves. It does not damage any of the electrode devices. Therefore, it is reported that the performance-stable laboratory ultrasonic cleaning can ensure detection accuracy under long-term operating conditions. Therefore, most of the pH electrodes are now beginning to use laboratory ultrasonic cleaning to help clean. During the cleaning process of the pH electrode, the pulse of the laboratory ultrasonic cleaner automatically implements width modulation. Its output is adjusted based on the size of the pH electrode to achieve optimum cleaning ability.
The above is the answer about how the laboratory ultrasonic cleaner cleans the PH electrode. Now you should have a base understanding of how the laboratory ultrasonic cleaning works after reading the above. You probably are shocked by the practicality and advantageousness of laboratory ultrasonic cleaner. If you have some doubts about the cleaning capacity of the laboratory ultrasonic cleaning, you can purchase a laboratory ultrasonic cleaner to experience the advantages.
