Pipettes are a type of lab equipment used to measure and transfer very small volumes of liquid. Accuracy in pipette measurement is necessary as any discrepancy in volumes dispensed can affect the results of an experiment. To ensure accuracy, it is necessary to check pipette calibration every few months.
The calibration process helps to check whether or not the equipment is dispensing the proper volumes so it can be fixed if it is not. To check the calibration of a pipette, you will need the pipette, pipette tips, distilled water, a beaker, a thermometer, a balance, and weigh boats. The balance needs to be specific to micrograms to calibrate micropipettes with a maximum of 1 µL. Fill the beaker with the water. Make sure the pipette tips are the correct tips that properly fit the pipette. Measure the temperature of the distilled water. Place the thermometer in the water and leave it for at least one minute.
If the red line on the thermometer is still moving, leave it for another minute. After a minute, record the temperature in a notebook. Remove the thermometer and dry it off when you are finished. Knowing the temperature of the water is important for the calculations that will be done to check the calibration. Place the weigh boat on the balance and zero it out. Ideally, you will use a balance that has doors on it and is an isolated chamber. Place the weigh boat in the chamber and close the doors.
