Tips: Pipette Calibration

After cleaning, the pipette needs to be calibrated. The pipette must be calibrated at room temperature (25 +/- 2 ° C). Referring to the instructions of the pipette, different ranges of 200µL/1000µL/5000µL/10000µL must be calibrated separately.

1. Remove the air bubbles from the pipette head and select the range to be calibrated.

2. An empty container was tared on an electronic balance with an accuracy of 0.1 mg.

3. Press the dosing key, add water to the empty container, weigh it, and record the reading.

4. According to the national standard, the calibration of pipettes uses the "three-point test (100%, 50%, and 10% of the maximum range), six times per point" rule. But suppliers usually choose two rules: one is simple calibration, that is, two-point test (100% and 10% of the maximum range), four times per point; the second is strict calibration, that is, three-point test (100%, 50%, and 10% of the maximum range), ten times per point. The user selects a rule according to the actual needs and then goes on to the calculation link after completing the test. (Adjust the pipette according to the absolute difference between the average value and the actual value, and use a tool to tighten the tension of the spring buckle)
