The other apparatus consists of a burette, beaker and stirrer. A volumetric burette delivers measured volumes of liquid. This siphons water into the burette which pushes the gas into the absorption vessel. The burette clamp will then be put between the rubber knobs. Usually burette clamps come in doubles, which means they can hold two burettes. A weight burette delivers measured weights of a liquid. Specification is directly association with the usage of each laboratory equipment including burette. These involve using equipment such as a burette. The liquid in the burette should be completely free of bubbles to ensure accurate measurements. The 9th Hussars were mobilized on 2 August 1914, commanded by Colonel Burette. Burette clamps can be made with many materials such as plastic and cast iron.
