Nevertheless, when the greatest feasible accuracy is sought after, It's not at all adequate to simply empty pipettes which are altered to consist of by blowing out the liquid that has a pipetting aid; these pipettes must also be rinsed two to 3 times With all the diluting medium.
The Operating principle of a pipette requires drawing up a certain quantity of liquid to the pipette and after that transferring it to another container, both by utilizing the pipette’s launch mechanism or by blowing it out.

The accuracy of the pipette will depend mainly on the type in problem. The level of precision are going to be depending on the degree to which the sent quantity matches with the volume specified over the instrument. The problem of kit and use of pipetting strategy will also have some impact on accuracy.
