Typical Laboratory Equipment You will be expected to memorize a collection of different pieces of lab equipment. You will need to know these items by sight and be able to provide the proper use for each. As a tool to help you study, I have put together a photo collection of the items you will need to know. I hope this helps you score well when I test you! You will be expected to memorize a collection of different pieces of lab equipment.
