Name:________________________________________________________________ Pd:_____ Date:__________________ Lab Equipment Identification Worksheet Part I: Description of Lab Equipment You will need to know the purpose for the different lab equipment, we may use throughout the school year. Read the name, and function for each piece of equipment, then draw, the picture of that piece of lab equipment in the box. You may use your learning device to look up images of the ones you do not know. Name Bunsen burner Evaporating dish Beaker Ring stand Function Lab equipment which produces a single open gas flame, which is used for heating, sterilization, and combustion Device used to evaporate solids and supersaturated liquids Probably the most common vessel for holding liquids in the lab. Is used as a reaction chamber. THIS IS NOT A DEVICE FOR MEASURING LIQUIDS. Used in many lab activities as the support for another apparatus. Picture Name Function Pipestem “Clay” triangle Can be placed on an iron ring to provide a stage for a crucible Test tubes Used for many activities which requires multiple reagents or solutions Utility clamp May be attached to a ring stand and be made to hold a test tube or thermometer Iron ring Often attached to ring stand to use as support for a beaker 1 Picture Funnel May be placed in an iron ring. Used for filtration or the delivery of liquids. Wire gauze Often placed over the iron ring, to provide a “stage” for a beaker Watch glass Used in chemistry as a surface to evaporate a liquid, or as a cover for a beaker Erlenmeyer flask May be used to hold liquids instead of beakers, when a smaller opening is preferred. Rubber stoppers & Corks Used to contain liquids in test tubes and flasks Tongs Used to handle hot beakers and other glassware Glass stirring rode To mix or stir substances. Made of glass to resist heat, stains, and corrosion. Graduated cylinder Used for measuring and pouring liquids; NOT for heating or mixing substances. Mortar & pestle tool used to crush, grind, and mix solid substances Safety goggles MUST be worn for ALL lab activities to protect the eyes, when glass, heat, and chemicals are used. Pipets, Micropipets & Droppers Wash bottle A pipette (also called a pipet, pipettor or chemical dropper) is a laboratory instrument used to transport a liquid, of one type to the reaction chamber. A squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks. 2 Test Tube Brush (wire brush) This is a small brush used to clean the inside of test tubes. Remember not to ever force anything inside a test tube. Well plate is a flat plate with multiple "wells" used as small test tubes Spatula & Scoopula A spatula is used to take and handle small quantities of solid chemicals. It serves as a spoon. Crucible & cover Container which can withstand high temperature and is used for metal, glass, and pigment production Striker Used for creating a spark, in order, to light a Bunsen burner. Test-tube rack Used to hold test tubes. Can be used while waiting on reactions to take place. Part II: Identify which piece or pieces of lab equipment you need for the following. You may use more than one piece of lab equipment. 1) Holding 50 mL of boiling water: ______ ___________________________________ 2) Crushing large chunks of sodium chloride:___________________________________________ 3) Must be worn, ALWAYS, to protect your eyes from heat, glass, and chemicals:________________________ 4) Measuring exactly 43 mL of water: _______________________________________ 5) Holding a test tube over a flame:__________________________________ 6) Adding 10 drops of iodine to a solution:____________________________________ 7) Suspending glassware over a Bunsen burner:________________________________ 3 8) Cleaning the products of a chemical reaction out of test tube:__________________________ 9) Keeping the contents of a boiling beaker from splattering:_____________________ 10) Transferring a hot beaker from a hot plate to cool:___________________________ 11) Used to produce a flame during a chemistry lab:_______________________________ 12) Mixing many different solutions to compare pH:____________________________. 13-17) Diagram A shows a typical setup for boiling a liquid. In the boxes provided, name the five items used. Diagram A: Boiling a Liquid 13. 14. 15. 16. 17. 4 5
