Common Laboratory Glassware and Apparatus

Common Laboratory Glassware and Apparatus


Erlenmeyer flask (conical flask) 
Used for titration or filtration of liquids and to prevent air contamination to sample during work
Beaker
Used for measuring liquid roughly volume with low accuracy
Graduated cylinder
Used for measuring liquid with better accuracy than beaker
Test tube holder
Used for holding test tubes
Crucible
Used for burn sample at high temperature
Mortar and Pestle
Used for graining materials which have large particle size to small
Round bottom flask
Used for distillation or heating of  liquid, allows uniform heating
Volumetric flask
Used for measuring liquid with high accuracy
Pipette
Used for transfer exact amount of liquid
Separatory funnel
Used for Liquid-Liquid extracts, designed for increase separation efficiency
Buchner funnel

Heat Mantle
Used as source of heat, mainly for distillation system
Centrifuge
Used for separation of precipitations from supernatant
Balance
Used for measuring mass of materials
Burette
Used for titration where titrant pored inside
Burette Clamp
Used along with stand to hold burette
Bottle top dispenser
Used for transfer accurate amount from the bottle (mostly used for acids and organic solvent)
