Common Chemistry Lab Equipment

The Tools of Science

Safety Goggles

Must be worn for all Chemistry labs

Protects eyes from chemicals

Beaker

Used to hold and transfer liquids

Used to make approximate measurements.

Use a beaker that is about twice the capacity of the volume of liquid you need to hold

Not this one

THIS ONE!

Beaker Tongs

Used to transfer hot beakers

Coated with plastic that can MELT!

Crucible Tongs

Used to hold crucibles and very hot items.

Erlenmeyer Flask

Used to hold and transfer liquids

Can be stoppered

Graduated Cylinder Used to measure exact volumes Measure the volume from the bottom of

the meniscus.

Meniscus

Watch Glass

used as a surface to evaporate a liquid, to hold solids while being weighed, or as a cover for a beaker

Test Tubes and Test Tube RackTest tubes are used to carry

out chemical reactions.When not in a test tube holder

or clamp, put test tubes in a test tube rack.

Burette

Dispense exact volumes of liquid.

They are used during a process called titration.

Volume measured from the bottom of meniscus

Ring Stand and Iron Ring

Provide structural support for various attachments that are usually used to hold glassware

The iron ring holds a wire gauze, triangle, or funnel on the ring stand.

Utility Clamp

Used to hold glassware in place on the ring stand.

Triangle

Rests on iron rings and are used to hold funnels during filtering or crucibles during heating.

Wire Gauze

Covers the iron ring to provide a flat surface for beakers when heating them.

Funnel

Can be used with filter paper to filter fluids. They can also be used for transferring fluids.

Crucible

Used to hold small amounts of a substance to be heated or dehydrated.

Striker

Produce sparks to light Bunsen burners

Bunsen Burner

Produce a flame used to heat, dehydrate, or sterilize substances in the lab

Hot Plate

Used to heat solutions.

Mortar and Pestle

Used to grind solids into powders

Thermometer

Used to measure temperature.

NOT FOR STIRRING!

Stirring Rod

Used for stirring chemicals

Scoopula

Used to transfer solids

Used to transfer small quantities of liquids

Disposable Pipette

The Test Tube Brush

FOR YOU to use to clean test tubes and graduated cylinders

Not for Mr. S or your parents

**A VERY IMPORTANT PIECE OF EQUIPMENT**
