California Calibration Services

Pipettes are necessary equipment often used in chemical laboratories to calculate plus transfer certain quantity of liquid. Pipettes are generally narrow tube like equipment with a rubber bulb at the top. The tube is numbered from the top to the bottom basically in increments of ten millimeters. Accuracy and reliability in pipette measurement is important as any difference in reading may affect the result of chemical reaction. To guarantee accuracy it is crucial to execute pipette calibration at routine intervals. Calibration of equipment is desirable even in the most enhanced equipment as overtime many aspects may affect the readings of measuring equipment. Calibration process helps you to check out whether or not the tools are giving appropriate reading so that it may be fixed in time and so efficiency of procedures or even laboratory test is maintained.

Given here are suggestions that will help carry out pipette calibration all on your own.

Step 1

Clear the pipette as well as the beaker. Dry it out completely. This is achieved to remove any past residue that could affect the results.

Step 2

Put some distilled water in an Erlenmeyer flask. Let it stick out on a bench for about fifteen minutes. Now, measure the temperature of the water.

Step 3

Find out the mass of the beaker to the nearest tenth of a milligram, using a balance.

Step 4

Now, using a pipette filler fill up the pipette using the water from the flask. Move this water into the beaker. Weigh the beaker again. Make a note of the difference in weight of the beaker and even analyze the mass of water released. Carry out this process three more times.


Step 5

Analyze plus figure out the mean of the four pipette measurements.

Step 6

Make an addition of 1.06 mg for each gram to the mean mass to regulate for the buoyancy of air in the weighing. Do not follow this step when you are using a digital scale.

Step 7

Assess the density of water at the temperature you measured earlier in the process.

Determine the mean amount of water discharged by the pipette using the formula: Volume = mass / density.

Step 8

To check the perfection of your pipette make a comparison of your measurement plus calculations to other results in pipette calibration procedure.
