Common Laboratory apparatus refers to the various tools and equipment used in Chemistry and research. These 50 Common Laboratory Apparatus help in conducting experiments, measuring substances, heating, mixing, and analyzing chemicals and materials. Common Laboratory Apparatus are tools and devices used in scientific research, diagnostics, and industrial applications to measure, analyze, and manipulate materials. These instruments vary in complexity, from simple measuring devices to highly sophisticated analytical machines.
