Lab Equipment Flashcards
Balance
The only piece of equipment we us to precisely measure the mass of a substance
Beaker
Large mouth glass containers used to contain approximate volumes of liquid
Buret
Long tube with a stopcock that opens and closes. It is used to deliver volumes of solutions, especially in an acid/base titration. They count backwards because they measure how much liquid has been delivered
Erlenmeyer Flask
Small mouth glass container used to contain approximate volumes of liqiud. The small mouth accommodates a stopper for storage or to prevent spillage while mixing
Graduated Cylinder
Used to measure and deliver precise volumes of liquids
Test Tube
Glass cylinder that contains liquids being tested in an experiment. Doesn’t have any measurement markings on it.
Volumetric Flask
Used to precisely make a specific volume of an aqueous solution (aqueous = water + dissolved compound)
Pipet
Deliver precise volume
Beaker Tongs
Circular tongs with rubber coating that can wrap around and hold a hot beaker
Bunsen Burner
Gas flame burner that uses methane as a fuel source
Clay Triangle
Set on a ring clamp, it is used to support a crucible or a funnel
Crucible
Ceramic bowl lid that is used to heat small amounts of solid substances to high temperatures
Crucible Tongs
Used to pick up and hold small items, such as crucibles
Double Buret Tongs
Attaches to ring stand to hold two burets
Evaporating Dish
Used to contain small volumes of solutions in order to heat the mixture and evaporate the solvent
Hot Hands
Silicon hot pads that can withstand high temperatures and are used to hold/transfer hot containers
Ring Clamp
Ring-shaped clamp that attaches to the ring stand to support equipment
Ring Stand
Long metal pole on a base. Along with clamps, it is used as a support of equipment set-ups
Scoopula
A folded piece of metal that is used to transfer solids
Spot Plate
A plastic of porcelain plate with wells used to test reactions during micro labs. Sometimes called a “well plate”
Striker
Has a flint that sparks to initiate flame on Bunsen burners
Test Tube Clamp
Clamps a test tube or equipment onto a ring stand
Test Tube Holder
Spring metal holder used to hold or transfer hot test tubes
Transfer Pipet
Plastic, qualitative pipet that is used to dispense chemicals. Often used in place of a dropper
