Used to hold and heat liquids. Multipurpose and essential in the lab.

Used for heating and exposing items to flame

used to heat small quantities to very high temperatures

Used to heat and store liquids. The bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat.

used to heat and evaporate liquids

used for heating substances that need to be heated evenly The curved bottom allows the heat to distribute through the liquid more evenly

used to target liquids into any container so they will not be lost or spilled

Used to Measure mass

used for moving small amounts of solid from place to place.

used to crush solids into powders for experiments

used for moving small amounts of liquid from place to place. They are usually made of plastic and are disposable

used to hold items being heated Iron ring

used to easily clean the inside of a test tube. used to easily clean the inside of a test tube.

used to hold test tubes when they are hot and untouchable

used to hold test tubes while reactions happen in them or while they are not needed

used to hold many different things such as flasks, crucibles, and evaporating dishes when they are hot.

used to measure one specific volume. They are mostly used in mixing solutions

used to accurately measure out volumes of liquid chemicals

Used to pick up small solid pieces Of chemicals

used to support a container (such as a beaker or flask) during heating. When the Bunsen burner flame is beneath it, the wire gauze helps to spread the flame

Used to Measure small Amounts of Liquid by drops
