How it is used

Used constantly in analytical and biochemistry labs, also as a verb: 'pipette 10 mL of the sample'. You use a pipette filler or bulb, change the tip and never pipette by mouth. US texts sometimes spell it 'pipet'.

Example sentences

  2. Never use your mouth to fill a pipette; use a pipette filler.

Common collocations

  • volumetric pipette
  • Pasteur pipette

  • buretteA long, graduated glass tube with a tap (stopcock) at the bottom, used to add a liquid gradually and measure exactly how much was added, mainly in titrations.
  • volumetric flaskA pear-shaped flask with a long narrow neck and a single line marked on it. Filled to that line, it holds one exact volume, so it is used to prepare standard solutions.
  • graduated cylinderA tall, narrow cylinder with volume markings on its side, used to measure liquids more accurately than a beaker but less accurately than a pipette or burette.
  • titrationA method for finding the unknown concentration of a solution by adding a solution of known concentration from a burette until the reaction between them is just complete.
