Final answer:
The range of measurement for each pipette is crucial for laboratory accuracy and precision, with micropipettes suited for small volumes and volumetric pipettes for fixed precise volumes. Proper use and sterility considerations are also key to ensuring accurate results.
Step-by-step explanation:
It is important to note that various types of pipettes have different ranges of measurement and precision levels suitable for different tasks in a laboratory setting. For instance, micropipettes with ranges of 2-20 µl and 20-200 µl are designed for dispensing very small volumes, whereas a volumetric glass pipette with a fixed volume of 3.00 ml is best for transferring precise quantities of liquid when such accuracy is vital. The precision of these instruments is crucial when conducting experiments, particularly when making dilutions or adding reagents to a reaction. Correct usage, such as ensuring the pipette is level and your eye is at the top level of the liquid, greatly affects the accuracy and precision of measurements. Additionally, considerations of sterility may be imperative for successful experimental outcomes, especially when working with biological samples or when contamination could skew results.
