Evaporating Dish The evaporating dish is used for the heating of stable solid compounds and elements.
Clay Triangle The clay triangle is used as a support for porcelain crucibles when being heated over a Bunsen burner.
Ring stands and their Components Ring stands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.
Ring stands and their Components Iron Rings Iron rings connect to a ring stand and provide a stable, elevated platform for the reaction.
Ring stands and their Components Utility Clamps Utility clamps are used to secure test tubes, distillation columns, and burettes to the ring stand.
Ring stands and their Components Double Burette Clamps Double Burette clamps are used to burettes – long graduated tubes used in titration.
Ring stands 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!
Thermometer Never Shake a thermometer Never put a thermometry directly into a flame
Disposable Pipette Transfers liquids Its disposable
Medicine Dropper A medicine dropper is used to transfer a small volume of liquid (less than one mL). On top of each medicine dropper is a “rubber bulb”
Wash Bottle A wash bottle has a spout that delivers a wash solution to a specific area. Distilled water is the only liquid that should be used in a wash bottle.
Electronic Balance Using the Electronic Balance Scale – Obtain the chemical. – Turn the balance ON. – Place an empty weighing boat on the balance. – Press TARE. (the balance will now read “0”) – Carefully add the chemical. Using a spatuala – When you are done, press OFF. – Clean up any spills around the balance and on the table top.
