Slide 1 Laboratory Equipment

Slide 2 Beaker Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated. Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.

Slide 3 Beaker Tongs Beaker tongs are used to move beakers containing hot liquids Beaker tongs are used to move beakers containing hot liquids

Slide 4 Graduated cylinder A graduated cylinder is used to accurately measure volumes of liquids. A graduated cylinder is used to accurately measure volumes of liquids.

Slide 5 Erlenmeyer Flask Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated. Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.

Slide 6 Ring Stand Ringstands holds iron rings that allow a safe and convenient way to perform reactions that require heating using a Bunsen burner. Ringstands holds iron rings that allow a safe and convenient way to perform reactions that require heating using a Bunsen burner.

Slide 7 Wire Gauze Wire gauze sits on the iron ring to provide a place to stand a beaker. Wire gauze sits on the iron ring to provide a place to stand a beaker.

Slide 8 Clay Triangle The clay triangle is used as a support for porcelein crucibles when being heated over a Bunsen burner. The clay triangle is used as a support for porcelein crucibles when being heated over a Bunsen burner.

Slide 9 Crucible and cover Crucibles are used for heating certain solids, particularly metals, to very high temperatures. Crucibles are used for heating certain solids, particularly metals, to very high temperatures.

Slide 10 Crucible tongs For handling hot crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers! For handling hot crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers!

Slide 11 Bunsen burner and hose Bunsen burners are used for the heating of nonvolatile liquids and solids. The hose is the carrier of gas to the Bunsen burner. Bunsen burners are used for the heating of nonvolatile liquids and solids. The hose is the carrier of gas to the Bunsen burner.

Slide 12 Striker Strikers are used to light Bunsen burners. Strikers are used to light Bunsen burners. The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks! The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks!

Slide 13 Test Tube Used to hold small amounts of liquids.

Slide 14 Triple beam balance Used to measure masses very precisely. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero.

Slide 15 Scoopula Used to scoop small amounts of solid (fine powders, crystals) out of their containers.

Slide 16 Stirring rod A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution. A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution.

Slide 17 Things to know for sure! Know the difference between a beaker and an Erlenmeyer flask. (Which piece of glassware can we heat to a higher temperature and why?) Know the difference between beaker tongs and crucible tongs. (Beaker tongs- used for hot beakers, have black heat- resistant ends. Crucible tongs- used for hot crucibles, are completely made of metal and have a “nose” at the end made for grasping small equipment)
