Laboratory tools are used to make precise and accurate measurements in labs. Some common tools include triple beam balances for measuring mass, graduated cylinders for measuring liquid volumes, test tubes for storing and heating liquids, beakers for storing and measuring liquid volumes, and rulers, meter sticks, and tape measures for measuring length. Other tools shown are spring scales for measuring weight, thermometers for measuring temperature, microscopes for viewing small objects, telescopes for viewing distant objects, and stopwatches for measuring time.

2. Triple Beam Balance A triple beam balance is used to measure the mass of solid objects. It has three beams that each measure mass to a different unit place (ones, tens, hundreds). Units of mass include milligrams, grams, and kilograms.

4. Test Tube A test tube is a long, narrow type of glassware in which liquids can be stored and heated. Test tubes have round bases and are stored in test tube racks or mounted on test tube stands.

5. Beaker A beaker is a type of glassware. It can be used to store liquids, heat liquids, and measure the volumes of liquids. Beakers have broad, flat bases. Beakers usually measure liquid volumes in milliliters (mL).
