• Dispensing eye drops into the eye was a common application.
  - Although various designs of both plastic and glass droppers exist, the most popular is a glass tube tapered to a small tip (a pipette) and equipped with a rubber bulb at the top.
• The pipette and rubber bulb combo has also been referred to as a teat pipette.
  - The Pasteur pipette gets its name from French scientist Louis Pasteur, who used a variation of it frequently during his studies.
• There was no apparatus to transport a chemical solution without exposing it to the outside environment in the past.
