lab equipment Flashcards
a safe and convenient way to perform reactions that require heating using a bunsen burner
RIng stands
used to weigh solids that will be transferred to another vessesl
weighing boat
hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated
beaker
used to hold a small amount of solid, such as the product of a reaction
watch glass
used for the heating of a nonvolatile liquids and solids
bunsen burner
used to dispense solid chemicals from their containers - chemicals should never be transferred with bare hands
spatulas
used to aid in the transfer of liquid from one vessel to another
funnel
iron ring
connect to a ring stand and provide a stable, elevated platform for the reaction
used to move beakers containing hot liquids
beaker tongs
filled with liquid for collecting gases in bell jars or the like by displacement
water through
(tweezers) used to pick up small objects
forceps
used for heating certain solids, particulary metals, to very high temps
crucible
used in first-year chem, used for the mixing of chemical, narrow neck prevents splash exposure
Florence flask
provide a surface for semi-micro scale experiments, such as drop reactions and testing of acids and bases
glass plates
for handling hot crucibles, and also used to pick up other hot objects. NOT to be used for picking up beakers
crucible tongs
measures and deli vers exact volumes of liquids
pipet
to weigh 2 objects to same weight
balance
used to manually stir solutions, also used to transfer a single drop of solution
stir rod
used to a support for porcelain crucibles when being heated over a bunsen burner
clay triangle
for holding a test tube which is too hot to handle
test tube holder
used to transfer a small volume of liquid
dropper
to hold small amounts of liquids
test tube
used to secure test tubes, distillation columns, and burets to the ringstand
utility clamp
sits on the iron ring to provide a place to stand a beaker,
wire gauze
used for the heating of stable solid compounds and elements
evaporating dish
used to measure volumes of liquids
graduated cylinder
has a spout that delivers a was solution to a specific area, distilled water is the only liquid that should be used in a wash bottle
wash bottle
for holding and organizing test tubes on the laboratory counter, plastic racks may melt if touched by hot test tubes
test tube racks
hold solids or liquids that may release gases during a reaction or that are likely to splatter if sturred to heated
Erlenmeyer flask
