Test Tube

Collecting Bottle Usually for collecting gas, but can collect liquids from an experiment as well.

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.

Florence Flask Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.

Beaker Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.

Graduated Cylinder A graduated cylinder is used to measure volumes of liquids.

Spring Scale measures weight by the distance a spring deflects under its load.

Triple Beam Balance used in the laboratory to determine the weight or mass of things

Electronic Balance Measures weight/ mass digitally

Thermometer device that measures temperature

Medicine Dropper Used to transfer a small volume of liquid

Thistle Tube Used to add liquid to an existing system

Funnel A funnel is used to aid in the transfer of liquid from one vessel to another.

Delivery Tube Bent Glass Tubing: gases which evaporate when a liquid is heated can be 'directed' to another part of the apparatus.

Rubber Tubing Transfers liquid or gas from one place to antoher

Test Tube Holder useful for holding a test tube which is too hot to handle.

Forceps used to pick up small objects.

Clamp Utility clamps are used to secure test tubes, distillation columns, and burets to the ringstand.

Tongs Beaker tongs are used to move beakers containing hot liquids Crucible Tongs for handling hot crucibles

Ring clamp Iron rings connect to a ringstand and provide a stable, elevated platform for the reaction.

Clamp Stand Ringstands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.

Test Tube Stand

Bunsen Burner Bunsen burners are used for the heating of nonvolatile liquids and solids.

Alcohol Burner In place of bunsen burner; provides a hot, consistent flame.

Wire Gauze Wire gauze sits on the iron ring to provide a place to stand a beaker

Evaporating Dish The evaporating dish is used for the heating of stable solid compounds and elements.

Safety Goggles Eye protection from chemicals, etc

Hot Plate small electric stove used in laboratory settings to heat glassware

Crucible and Cover Crucibles are used for heating certain solids, particularly metals, to very high temperatures.

Clay Triangle The clay triangle is used as a support for porcelein crucibles when being heated over a Bunsen burner.

Mortar and Pestle used to crush, grind, and mix substances.

Stopper Rubber stoppers are used to close containers to avoid spillage or contamination. Containers should never be heated when there is a stopper in place.

Stirring Rod A glass rod is used to manually stir solutions.

Spatula Spatulas are used to dispense solid chemicals from their containers. Chemicals should never be transferred with your bare hands.

Scoop

Watch Glass A watch glass is used to hold a small amount of solid, such as the product of a reaction.

Hand Lens Simple microscope

Petri Dish and Cover Used to culture cells/ bacteria

Glass Slide with Coverslip he object to be viewed is typically placed on the middle of the slide with another, much thinner square of glass placed over the specimen…creates even surface for viewing

Dissecting Tools Scalpel: small but extremely sharp knife used for surgery or dissection Dissecting Needles: helps you cut open the object you are dissecting
