Pasteur pipettes are also referred to as eyedropper pipettes. They can be solitary-use pipettes used to transfer small amounts of liquids.
Named soon after Emil Erlenmeyer, a German organic chemist who intended the flask, Erlenmeyer flasks are available in multiple sizes. As with beakers, these flasks could possibly or might not have quantity marked. They can be exact to in about 10%.
These pipettes are able to staying really exact and exact. Even so, considering that they depend on air displacement, They can be topic to inaccuracies caused because of the modifying atmosphere, especially temperature and consumer procedure. For these motives, this devices needs to be cautiously taken care of and calibrated, and consumers should be trained to physical exercise appropriate and steady method.
