Pipettes are necessary equipment often used in chemical laboratories to measure and transfer specific amount of liquid.

1. Tips to Perform Pipette Calibration
• Pipettes are necessary equipment often used in chemical laboratories to measure
and transfer specific amount of liquid.
• Pipettes are essentially narrow tube like equipment with a rubber bulb at the top.
• The tube is numbered from the top to the bottom mostly in increments of ten
millimeters.
• Accuracy in pipette measurement is necessary as any discrepancy in reading can
affect the result of chemical reaction.
• To ensure accuracy it is necessary to perform pipette calibration at regular
intervals.
• Calibration of equipment is desirable even in the most advanced equipment as
overtime several factors can affect the readings of measuring equipment.
• Calibration process helps to check whether or not the equipment is offering
correct reading so that it can be rectified in time and efficiency of processes or
laboratory test is maintained.

2. Given below are instructions to help you
perform pipette calibration on your own.
• Things needed:
 Beaker
 Erlenmeyer flask
 Pen and paper
 Pipette
 Pipette filler
 Thermometer
 Weight balance

Note down the difference in weight

out this process three more times.

mass / density.

6. It is important to ensure your laboratory is clean and
organized when carrying out calibration.

7. You are not required to clean and dry the beaker following each of the
four pipette measurements as doing this will only waste your time.

8. Take help of pipette calibration service provider
• Even after taking precautions and doing all the steps correctly, there are chances
that your calibration process may not offer you precision in results. Besides, you
may not like to use your valuable resources for this purpose. A great way to help
you carry out pipette calibration work with accuracy is to take help of professional
pipette calibration service providers. Certified agencies keep an array of
sophisticated equipment and have a team of experience technicians to conduct
calibration of equipment with precision and care, thereby helping you carry out
laboratory tests with efficiency.
