Unit 1 Chemistry Lab Equipment

A Triple Beam Balance is 

• Used to measure the mass of an object
• Used to measure the volume of an object
• Used to measure the density of an object
• Used to measure the weight of an object

Beakers are used

• to measure volume with high accuracy and precision
• to hold small amounts of dry chemicals
• to recover dissolved solids
• to measure approx. volumes and observe reactions
