Lab Equipment (42 equipments goodluck hehe)

Beakers

are used for holding various chemicals.

Not for measuring precisely.

Sizes vary.

Graduated Cylinder

Used to precisely measure the volume of liquids or run experiments.

Read from the meniscus at eye level.

Plastic ring always on top if applicable.

Sizes vary

Erlenmeyer Flask

Used to approximately measure the volume various liquids. • Useful for mixing by swirling • Sizes vary

Florence Flask

Used to boil liquids. • Also used to collect gases, if applicable. • Sizes vary.

Volumetric Flask

Used to prepare precise standard solutions. • They are only good for 1 specific volume. • Comes in many sizes

Reagent Bottle

Used to store, transport, or view reagents such as acids or bases.

Rubber Stoppers

• Used to close flasks and test tubes. • The holes allow the insertion of glass tubing, probes, or thermometers as needed by theexperiment.

Test Tubes and Rack

• Used to hold chemicals/tubes while experimenting.• Not for measuring precisely. • Aim away from faces. • Sizes vary. Label them

Distillation Flask

Used to separate liquids based on boiling point

Buret and Buret Clamp

Used for precisely measuring dispensed liquids • Holds it to ring stand

Ring Stand and Ring Clamps

Base/Pole of set-up for experimenting. • Holds glassware in place for heating or evaporating.

Test Tube Brushes

• Cleaning. • You must clean tubes before and after you use

Test Tube Holder

Used for carrying or holding hot test tubes

Thermometer

Measuring temperature. • Use metric!

Hot Plate

Used to heat substances

Bunsen Burner

Used to heat substances quickly or if > 400^oC is needed. • Do not use with flammable substances

Rubber Tubing

Used for a variety of things.

• Example:

• Connecting Bunsen burner to gas valve stem.

• Connecting glass tubing together

Wire Mesh or Gauze

• Used to absorb and spread the heat of flame. • Keeps glassware from cracking and breaking. • Part of ring stand set-up

Clay Triangle

• Used to hold a crucible in place on a ring stand. • Also helps absorb and spread heat of flame. • Part of ring stand set-up.

Crucible and Cover

Used for heating substances. • Can withstand high direct heat.

Crucible Tongs

Used to carry crucible.

Beaker Tongs

Used to carry beakers

Mortar and Pestle

Used to grind substances into powder or slurry.

Scoopula

• Used to scoop chemical powders. • Not a measuring instrument.

Stirring Rods

Used to stir substances. • Clean in between uses.

Striker

Used to ignite gas from a Bunsen burner. • Do not waste flint

Watch Glass

Used to show chemical reactions

Evaporating Dish

Used to evaporate excess liquids

Centrifuge

Used to separate suspensions (solids from liquids)

Meter Stick

Used to precisely measure length.

• 1m = 10dm

• 1m = 100cm

• 1m = 1000mm

Funnel

Used to safely transfer substances from one container to another

Dropper and Bottle

Used to measure out small amounts of liquids for experiments

Wash Bottle

Usually contains deionized water. • Handy for rinsing glassware and for dispensing small amounts of H2O for chemical reactions.

Goggles and Apron

Used to protect your eyes and clothing from damage. • These are a must in lab!!

Inoculating or Flame Loop

Used to collect samples from colonies (ex. Bacteria) • Also used to test the spectra of chemicals.

Digital Balance

Used to accurately measure mass. • Only up to 200g in our labs.

Triple Beam Balance

Measures the mass of an object. • Make certain the balance is calibrated correctly before use.

Double Pan Balance

Used to compare the masses of two substances

Centigram Balance

Used to precisely measure the mass of a substance. • More precise than the triple beam balance

Pipet, Pump, and Bulb

Used to precisely measure the volume of liquids in small amounts.

Berol Pipet

Disposable pipets used to transfer small amounts of chemicals. • Graduated pipets can precisely measure small amounts of chemicals.

Capillary Tubes

Used to collect liquid through the process of capillary action.
