are typically used to measure the volumes of gases or liquids. The valve at the
base can be used to control the flow of liquid from the device, thus allowing
measurements. Burettes are available with PTFE Key stopcock valves and screw
type needle valve. The gradations on the burettes should be clear and printed
neatly so the readings can be taken off the device without any confusion.
Burettes are available with different capacities ranging from 10 mLs to 100
mLs, so it can be chosen for the specific application.
