Lab equipment Flashcards
(28 cards)
For handling hot crucibles; also used to pick up other hot objects. Not to be used for picking up beakers.
Crucible Tongs
Ringstands and their components
Ringstands are a safe and convenient way to preform reactions that require heating using a bunsen burner
Mohr Pipet
A mohr pipet measures and delivers exact volumes of liquids
Scoopla
Scoopla are used to dispense solid chemicals from their containers. Chemicals should never be transferred with your bare hands.
Beaker Tongs
Beakers Tongs are used to move beakers containing hot liquids.
Weighing Boat
Weighing boats are used to weigh solids that will be transferred to another vessel
Florence Flask
Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.
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
Bunsen Burner
Bunsen burners are used for the heating of nonvolatile liquids and solids
Graduated Cylinder
A graduated cylinder is used to measure volumes of liquids.
Evaporating Dish
The evaporating dish is used for the heating of stable solid compounds and elements
Funnel
A funnel is used to aid in the transfer of liquid from one vessel to another
Test tube rack
Test tube racks are for holding and organizing test tubes on the laboratory counter. plastic racks may melt in contact with very hot test tubes
Beaker
beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated
Stir rod
A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of solution.
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.
Test tube holder
A test tube holder is useful for holding a test tube which is too hot to handle.
test tube
Small glass tube used to store or heat a small amount of chemical
Glass plate
Glass plates provide a surface for semi-micro scale experiments such as drop reaction and testing of acids and bases.
Forceps
are used to pick up small objects
Clay traingle
is used as a support for porcelein crucibles when being heated over a bunsen burner
Watch glass
Is used to hold a small amount of solid, such as the product of reaction
Crucible
are used for heating certain solids, particularly metals, to a very high temperature
test tube brushes
Are used to clean test tubes and graduated cylinders
