Laboratory Apparatus Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Bunsen burners are sources of heat. Burets are for addition of a precise volume of liquid. The volume of liquid added can be determined to the nearest 0.01 mL with practice. Clay triangles are placed on a ring attached to a ring stand as a support for a funnel‚ crucible‚ or evaporating dish.

use Erlenmeyer flasks to hold different layers of reactions‚ heat solutions‚ and grow liquid cultures of bacteria. Students and scientists use graduated cylinders as precise instruments for measuring out different liquids. Disposable Lab Ware Disposable lab ware‚ which includes a large variety of tubes and flasks‚ is essential to any functioning biological lab. Test tubes‚ culture tubes and tissue culture flasks all fall under this category. Scientists use culture tubes and flasks to grow bacteria
