1. The Importance of the Temperature Control Module During the PCR process, temperature changes directly affect the denaturation of DNA, primer binding, and the efficiency of the extension reaction. Therefore, it is crucial to ensure the accuracy and stability of the temperature control module. If the temperature control module is not accurately calibrated, it may cause the experiment to fail, thereby affecting the credibility of the research results.

2. Calibration steps 1. Preparation: Before starting calibration, please ensure that the Opentrons OT-2 workstation is connected to the power supply and running normally. Additionally, you will need a thermometer or thermocouple to measure the actual temperature. 2. Set the temperature: Through the Opentrons software interface, select the temperature control module to be calibrated and set the target temperature. Typically, the temperature settings for PCR reactions are 95°C, 55°C, and 72°C. 3. Measure the temperature: Wait for the temperature control module to reach the set target temperature, and use a thermometer or thermocouple to measure the temperature on the surface of the temperature control module. Please take care to ensure the calibration status of the measuring equipment so as not to affect the accuracy of the results. 4. Record data: Compare the measured actual temperature with the set temperature. Record the actual measured values ​​at each set temperature for subsequent analysis. 5. Adjustment and calibration: If there is a significant deviation between the actual measured value and the set value, the temperature control module can be adjusted through Opentrons software. Fine-tune as needed until the actual temperature matches the set temperature. 6. Verify calibration: After completing the calibration, perform a temperature measurement again to verify the accuracy of the temperature control module. Ensure consistent results at different temperature settings. 7. Regular calibration: In order to maintain the accuracy of the temperature control module, it is recommended to perform regular calibration, especially after completing a large number of experiments or when replacing important components.

3. Notes 1. When performing calibration, please ensure that the ambient temperature is stable to avoid the influence of external factors on the measurement results. 2. Use high-quality measurement tools to improve measurement reliability. 3. The calibration process should be recorded in the experiment log for future reference.

Through the above steps, you can effectively calibrate the temperature control module of the Opentrons OT-2 PCR workstation to ensure precise temperature control of the PCR reaction, thereby improving the success rate of the experiment and the reliability of the results. Whether you are a beginner or an experienced researcher, mastering the calibration skills of the temperature control module is the basis for ensuring that your experiments run smoothly. I hope this article can help you with your experiments and make your research go more smoothly!
