Question

What are 3 reasons why pipets are the most precise glassware?

Answer 1

1. Pipets are mean to hold a single specific volume.

2. You get a standard volume, check where the meniscus is and then create the mark for such volume. This greatly reduces the uncertainity for the given volumetric flask at a given temperature.

3. They generally deliver the specified volume of +/- 0.1 % an error of a few hundredths of a milliliter.

4. Use of volumetric pipet and micropipet give you way more precision than you can get by checking meniscus of the volumetric flask.
