Proper calibration ensures laboratory efficiency and accurate test results.
Tips to Perform Pipette Calibration
- 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
- 3. 1.Clean the Pipette : 2. Add Distilled Water: • Put some distilled water in an • Find out the mass of the beaker Erlenmeyer flask. Let it stand out to the nearest tenth of a on a bench for about 15 minutes. milligram, using a balance. Now, measure the temperature of the water.
- 4. 3. Taking Help of Pipette 4. Calculate and Filler: determine: • Now, using a pipette filler fill the • Calculate and determine the pipette with the water from the mean of the four pipette flask. Move this water into the measurements. beaker. Weigh the beaker again. Note down the difference in weight of the beaker and calculate the mass of water discharged. Carry out this process three more times.
- 5. 5. Adjusting the Buoyancy 6. Calculating of Air: Density of Water: • Make an addition of 1.06 mg per • Calculate the density of water at the gram to the mean mass to adjust for temperature you measured earlier in the buoyancy of air during the the process. Determine the mean weighing. Do not follow this step in volume of water discharged by the case you are using a digital scale. pipette using the formula: Volume = 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.
