Signal Words on Labels

Warning or Danger

Harmful, not deadly if dose is not too big

Burns, Eye damage, etc.

Can cause explosion

Aquatic Toxicity

Fatal/Toxic (Immediate)

Graduated cylinder

Measure the accurate volume of a liquid

Medicine dropper

Transfer small amounts of liquid

Beaker

Hold and heat liquids; used to measure approximate volumes

Rubber stoppers

Close container to avoid liquid loss; never place on a heated container

Erlenmeyer Flask

Heat, hold, and store liquids; narrow neck protects from hot splatters

Ring stands

Safe way to store/attach things

Florence Flask

Also known as a bubble flask, used to heat liquids

Test tube clamp

Holds a test tube

Watch glass

Holds small amounts of solids; do not heat; could be used as a cap

Iron ring

Connects to a ring stand as a platform

Test tubes

Heat, store, and mix small amounts of chemicals

Iron gauze

Attaches to the iron ring

Test tube brushes

Clean test tubes and graduated cylinders

Bunsen burner

Used for heating liquids and solids

Test tube holder

Holding a test tube that is hot

Striker

Lights Bunsen burner

Test tube rack

Holds and organizes test tubes

Wash bottle

Delivers wash solution, specifically distilled water

Evaporating dish

Used to separate solids dissolved in a solution from the liquid

Weighing boats/paper

Place chemical on it and then weigh

Well plate

Used to perform many small scale reactions at one time

Crucible

Used to heat solids to very high temperatures

Forceps

Tweezers used to pick up small objects

Crucible tong

Used to grab a crucible

Spatulas/scoopulas

Dispense solid chemicals from container; used for measurement

Clay triangle

Used as support for a crucible

Glass stir rod

Manually stir solutions; transfer a single drop

Burets

Measures the volume of gas

Funnel

Transfer liquids to another container

Meniscus

The curve at the top when measuring liquids

Reading a Meniscus

Read from the bottom of the meniscus at eye level to avoid parallax error

Reading Measurements

Read volume using all certain digits and one estimated uncertain digit

Thermometer placement rule

Do not touch the bottom of a flask being heated so you measure solution temperature, not glass temperature

Explosives, self-reactives, and organic peroxides

Flammables, pyrophorics, self-heating, and emits flammable gas

Gases under pressure

Carcinogens, respiratory sensitizers, and reproductive toxicity
