Lab Equipment and Measurements

Graduated Cylinder Measures volume of liquids Measures volume of liquids Unit: liter (L) Unit: liter (L) Commonly use mL in lab Commonly use mL in lab Proper Procedure: Place cylinder on a flat surface, get at eye level with the liquid, and read the bottom of the miniscus, the curved part of the top of the liquid. Proper Procedure: Place cylinder on a flat surface, get at eye level with the liquid, and read the bottom of the miniscus, the curved part of the top of the liquid.

Correct Technique!

Meniscus

Practice

Beaker Can be used to measure large volumes, but not as accurate as a graduated cylinder Can be used to measure large volumes, but not as accurate as a graduated cylinder Mainly used for pouring and mixing Mainly used for pouring and mixing Unit: mL Unit: mL

Triple-Beam Balance Measures mass (amount of substance – how much) Measures mass (amount of substance – how much) Unit: gram (g) Unit: gram (g) Procedure: Place balance on a flat surface, adjust masses until the arm balances. Take the sum of the 3 masses. Procedure: Place balance on a flat surface, adjust masses until the arm balances. Take the sum of the 3 masses.
