Used as a guide for transferring liquids.
Funnel
Used to measure the exact volume of substances, especially liquids. Has a neck lock. The neck lock prevents the beaker from breaking if ever it topples over.
Graduated Cylinder
Used for containers when observings how liquids spread and how liquids or chemicals mix.
Watch Glass
Used to contain substances in the lab and is used for approximate volume, and only approximate volume.
Beaker
Also used to measure approximate volume. Funnel-shaped because it is used for mixing substances.
Erlenmeyer Flask
Used for substances that are tested in the laboratory. Has a glass top cap and is held between the fingers.
Reagent Bottle
Container, for substances, that can be heated like the beaker and flask but not at very high temperatures.
Test Tube
Has a flat bottom and is slightly round. Used as a container for substances that are to be heated.
Florence Flask
Has a round bottom and is used for heating substances.
Round bottom Flask
Similar to the round bottom but has a sidearm. The side arm is known as your condenser. Used for distillation purposes.
Distilling Flask
Used to filter the flame of the bunsen burner.
Cobalt Glass
Used for flame tests and works together with the cobalt glass. Burning it would give different coloured flames. Has a looped tip, which is supposed to give a thin film of your liquid.
Nichrome Wire
It weighs solids you wish to dilute.
Volumetric Flask
Similar to the watch glass except it only uses a single drop, unlike the watch glass which uses plenty of chemicals. Used for qualitative analysis.
Spot Plate
Similar to a watch glass except it has grooves. Liquids will be thinly spread and the grooves assist in the evaporation process.
Speedyvap (Speedy Evaporation)
Used to pulverize or make solids smaller. Slow grinding motion in order to not spill its contents.
Mortar (bowl) and Pestle (rounded tool)
Contains substances that you would like to evaporate and dry out in order to see the remaining solid. Used to contain substances for evaporation or drying.
Evaporating Dish
Supposed to contain distilled water for rinsing your glassware, not metalware.
Wash Bottle
Used to support the funnel in the filtration of substances and as a support for glasswares that are being heated.
Iron ring
Used to hold glasswares in place.
Universal clamp and Condenser clamp
Used as additional support for the iron ring.
Wire triangle
Used to pick up hot objects and crucibles.
Crucible tong
Has three legs and is also used for supporting glassware that you are heating.
Tripod
Used to pick up hot test tubes.
Test tube holder
Used to transfer liquid from one container to another. Also known as dropper.
Mini pipette
Used to measure exact volume and works together with the aspirator. Has calibrations.
Pipette
Used for cleaning glassware.
Test tube brush
Used to produce the flame needed in heating substances in the lab.
Bunsen burner
Bunsen burner: Yellow flame
Luminous
Bunsen burner: Blue flame
Non-luminous
Used for transferring solids from one container to another.
Spatula
Used for stirring or mixing substances.
Stirring rod
Used for support for the glassware. Its main purpose is to spread the flame so the flame will not be concentrated in one area and will not damage the glassware.
Wire gauze
Containing water and has rings on top.
Water bath
Used to support test tubes
Test tube rack
Test tube holder __ the test tube while the test tube rack ___ the test tubes.
Holds; Supports
Sucks the liquid into the pipette
Aspirator
Used for gravimetric analysis
Crucible
Used for measuring the weight of objects.
Platform Balance and Triple Beam Balance
