Burets are devices used typically in analytical, quantitative chemistry applications for measuring liquid solution or gases. Differing from a pipette since the sample quantity delivered is changeable, graduated burets are used heavily in titration experiments. In bottom of the meniscus liquid measurement styles, the stopcock preventing leaks is located at the bottom of the vertical glass tube, while for gas models it is located at the top. For the most precise readings, digital options are available.
