Ever performed a titration in the lab only to find an absurd value? The process of reloading the burette might sound scary, but what’s worse is the fact that the analyte in your flask is now ruined. Even though the color in your flask isn\u2019t what it should be, the volume you need has already been dispensed from the burette. So now what to do? How did this happen? This is your chemistry lab burette\u2019s fault. Read along to find out how you can avoid this from happening to you ever again, by choosing the right chemistry lab burettes. <\/p>\n\n\n\n

What is a chemistry lab burette?<\/h2>\n\n\n\n

Chemistry lab burettes help dispense exact amounts of reagents drop by drop or in a stream. They are used for experiments in the school lab or for research in chemistry. Invented by Fran\u00e7ois Antoine Henri Descroizilles in 1791, the burette was later refined by Joseph Louis Gay-Lussac.<\/p>\n\n\n\n

What are the uses of a chemistry lab burette?<\/h2>\n\n\n\n

It helps researchers and students dispense exact proportions of liquids and gases, thereby helping determine the concentration of unknown solutions.<\/p>\n\n\n\n

One solution is tested against another. The burette contains the titrant, and the flask has the analyte with unknown concentration. The titrant is titrated from the burette against the analyte. This helps determine the concentration of the analyte in the flask.<\/p>\n\n\n\n

Types of chemistry lab burettes<\/h2>\n\n\n\n

Different types of burettes exist that help users perform different types of operations and experiments. Each type is optimised for a specific range of operations and must not be misused for others.<\/p>\n\n\n\n

The volume scale is printed on the burette wall. There is a plastic stopcock at the bottom that needs to be opened or closed in order to dispense the fluid. Gravity helps the liquid flow downwards. Because the opening is at the bottom of the burette, the level change is noted and corresponds to the amount of fluid dispensed. This is a manual burette, as it is handled by a human. The stopcock or valve is operated manually. It does not have a digital or electronic variant.<\/p>\n\n\n\n
