GRADUATED CYLINDER

Accurately Measures the volume of liquids in ml

PIPET

used to measure or transfer liquids

ASPIRATOR

suctions out air or liquid

BEAKER

holds solids or liquids

VOLUMETRIC FLASK

used to accurately prepare solutions

ERLENMEYER FLASK

used to mix, dissolve solids in solutions, and heat or cool solutions.

BURETTE

Accurately measures volume of liquids and dispenses small amount of liquid

THERMOMETER

measured temperature

ELECTRONIC BALANCE

weigh samples

ANALYTICAL BALANCE

a highly precise measuring instrument used to determine the mass of small samples with a high degree of accuracy and precision

TEST TUBE AND TEST TUBE RACK

for mixing, heating, and storing small quantities of chemicals

TEST TUBE HOLDER

used to hold and transport hot test tubes

TEST TUBE BRUSH

used to clean test tubes

EVAPORATING DISH

used to separate liquids and solid from a solution by allowing liquid to evaporate off into the air

IRON RING + IRON STAND

used for supporting and stabilizing laboratory apparatus and glassware

FUNNEL

used to pour liquids into narrow mouthed-containers and also used for filtering

WIRE GAUZE

diffuses heat and supports glassware during heating

DROPPER

used to transfer small volume of liquid, usually one drop at a time

BUNSEN BURNER

provides heat for performing experiments

ALCOHOL LAMP

heating, combustion, and sterilization in laboratory settings. It's a convenient and safer alternative to Bunsen burners for certain applications due to its lower, more controlled flame

for stirring mixtures and assists in pouring

MORTAR AND PESTLE

grinds solid into fine powder

SPATULA

used to transfer solid chemicals

DISTILLING FLASK

Separate mixtures of two liquids with different boiling points

SEPARATORY FUNNEL

used in extraction procedures to separate a mixture of two liquids with different densities into two separate parts

CRUCIBLE TONG

used for handling hot crucibles

CRUCIBLE AND COVER

used for heating solids to very high temperature

BURETTE CLAMP

used to secure burette

WATER BATH

Used for heating samples (usually for flammable chemicals) at a constant temperature for a long period of time

TRIPOD

supports apparatus during heating process

PRECAUTION ON THERMOMETER

•handle with care

• do not hold thermometer bulb while reading

• avoid sudden temperature change

•wash thermometer before and after

•never shake

•If broken, handle mercury with extreme caution

PRECAUTION ON EVAPORATING DISH

use tongs or heat resistant glove when dish is too hot

never touch the dish directly after heating

heat gradually

do not heat empty

avoid sudden temperature changes

PROPER HANDLING OF PIPET

clean before use

hold vertically

use pipet bulb or pump

never use mouth to draw liquid

avoid touching tip to avoid contamination

TRANSFERRING LIQUID CHEMICALS

carefully pour amount of reagent you need then close the bottle

never use any unused liquid back inti the bottle

TRANSFERRING SOLID CHEMICALS

use spatula clean, dry spatula

never return excess chemical to the container

avoid usung dirty or wet utensils when taking chemicals

label containers before and after use
