Alternatively, a beaker may be covered with another larger beaker that has been inverted, though a watch glass is preferable. Beakers are often graduated, that is, marked on the side with lines indicating the volume contained. For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume.
A volumetric flask (measuring flask or graduated flask) is a piece of laboratory apparatus, a type of laboratory flask, calibrated to contain a precise volume at a certain temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions .
Therefore, the more precise value equates to 36.5 0.1; 36.4 or 36.6 mL. Therefore, there are 3 significant figures can be read from the given graduated cylinder picture. [9] Another example, if the reading is done and the value calculated is set to be 40.0 mL. The precise value is 40.0 0.1; 40.1 or 39.9 mL.
A conical measure is a type of laboratory glassware which consists of a conical cup with a notch on the top to allow for the easy pouring of liquids, and graduated markings on the side to allow easy and accurate measurement of volumes of liquid. They may be made of plastic, glass, or borosilicate glass. The use of the conical measure usually ...

Volumetric flasks are for measuring a specific volume of fluid. Burettes are similar to graduated cylinders but have a valve at the end used to disperse precise amounts of liquid reagents often for titrations. [17] Glass pipettes are used to transfer precise quantities of fluids.
