It has a short glass tube about an inch away from the neck of the flask and acts as an

adapter.

It can be used with a Büchner funnel for separating solids and liquids.

Büchner funnel

Used as a filter and a funnel at the same time.

Separates a solid product from a solvent or liquid reaction mixture.

Gas collecting bottle

Used to collect a gas.

It is usually filled with water and the gas bubbled through the water into the bottle

Eye wash station

Used for washing out your eyes with water

When you get a chemical in your eye you should wash it out with water for 20 Minutes.

Beaker tongs

A grasping device consisting of two arms that are joined by a pivot or scissor like hinge.

Usually used to handle hot beakers.

Heat protective gloves

Used in chemistry for handling hot beakers and test tubes.

It can handle over many things besides heat, it can handle rough and sharp metal parts.

Stirring rod

A piece of lab equipment used to stir and mix chemicals for laboratory purposes.

Evaporating dish

Piece of glassware used for the evaporation of solids and fluids.

Eye dropper

Used to drop single droplets of liquid and to transfer small quantities of liquids

Clay triangle

Used to support items being heated by a Bunsen burner or other heat source.

Buret

Used to dispense measured amounts of a chemical solution.

Also used in titrations to measure precisely how much liquid is used

Desiccator

Sealable containers used for preserving moisture-sensitive items.

Test tube brush

Used to clean the inside of test tubes and narrow mouth glassware.

Flint striker

Used to start a fire with only sparks when you do not have a lighter or matches.

Used for crushing and grinding substances.

Magnetic stirrer

Uses a Rotating magnetic field to stir liquids.

Molecular model set

Used to make models that represent molecules and their processes.

Deionized water

Very pure water that does not contaminate results of experiments using water.

This water is water that had ions removed.

Used to transfer a measured amount volume of liquid

Wash bottle

A bottle that is squeezable with a end nozzle piece.

It is used to rinse laboratory glassware, such as test tubes and round bottom flasks.

Safety Goggles

Used to protect your eyes from sharp, hot or corrosive fragments/gasses/liquids

Cuvet

A small tube, sealed at one end, designed to hold samples for spectroscopic experiments

Crucible with cover

Used to hold smaller amounts of chemicals during high temperature heating.

The cover helps keep oxygen out of the reaction.
