Lab Equipment

Beaker - A container that holds the liquid chemicals and measures the volume of amount of liquid.

Tweezers - for grabbing substances.

Bunsen Burner - Used for heating and exposing items to flame.

Erlenmeyer Flask - Used to heat and store liquids. The advantage to this the bottom is wider than the top so it’ll heat quicker.

Overflow Can - Used to measure the volume of an irregular object.

G/sh Goggles - Must be worn for each lab activity to protect your eyes.

Thermometer - Used to take temperature of solids, liquids, and gases.

Dropper/pipette - For adding small amounts of chemicals

Scoopula - Used to transfer solid chemicals from the bottle

Petri Dish - A flat, shallow dish used to hold substances.

Test Tube - Used for storing things and performing small chemical reactions in a laboratory.

Flint Lighter - Used to produce a spark to light a Bunsen burner.

Wash Bottle - Used for cleaning of beakers and other glassware.

Glass Stirring Rod - Used to stir liquids.

Rubber Stoppers - These act as lids for Erlenmeyer flask - keep liquids contained.

Funnel - Used to target liquids to any container so they will not be lost or spilled.

Spot Plate - Used for extremely small chemical reactions.

Test Tube Tongs - Used to handle a single test tube.

Beaker Tongs - Used to handle hot beakers and other glassware.

Test Tube Rack - Used to hold test tubes while reactions happen in them.

Electronic Scale - Used to obtain measurements of masses.

Triple Beam Balance - Used to obtain precise measurements of masses.

Watch Glass - Used to evaporate off the liquid part of a solution.
