For handling hot crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers!
Glass plates provide a surface for semi-micro scale experiments, such as drop reactions and testing of acids and bases.
Triangular files are used primarily to cut glass rod, a skill that your instructor will share with you when it becomes useful.
Ringstands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.
Ringstands and their Components Iron Rings
Iron rings connect to a ringstand and provide a stable, elevated platform for the reaction.
Ringstands and their Components Utility Clamps
Utility clamps are used to secure test tubes, distillation columns, and burets to the ringstand.
Ringstands and their Components Double Buret Clamps
Double Buret clamps are used to burets – long graduated tubes used in titration.
Ringstands and their Components Wire Gauze
Wire gauze sits on the iron ring to provide a place to stand a beaker.
On older wire gauze, the white material is asbestos!
A 4” x 4” square of ceramic fiber, it provides a surface for hot beakers so that the beaker does not come in contact with a cold countertop and shatter.
Strikers are used to light Bunsen burners.
The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks!
