Lab Quiz 2: DIFFERENT LAB APPARATUS

Tirril Burner

Has gas regulator; safe continuous stream of flammable gas used for heating, sterilization, and combustion

Bunsen Burner

Single open gas flame; no gas regulator; most common type; gas can be natural gas or LPG (propane, butane, or mixture)

Fisher-Mecker Burner

Fisher-Mecker Burner

Multiple open gas flames; heating, sterilization, combustion; hotter flame than bunsen burner; bigger diameter; mostly for glass manipulation

Fishtail/Wingtop

Fishtail/Wingtop

Spreads heat in a bunsen burner over a large area; used to bend glass

Hotplate

Hotplate

Adjustable hot surface with temperature control; can perform reactions with magnetic stirrer

Alcohol Lamp

Alcohol Lamp

Uses ethyl alcohol or spirit as fuel; safer than bunsen burner; lower temperature; flame ~5 cm

Florence Flask

Florence Flask

For heating, boiling, distillation, and swirling liquids

Deflagrating Spoon

Deflagrating Spoon

Used for burning phosphorus, sulfur, or other substances; capable of high temperature

Crucible with cover

Crucible with cover

Contains chemical compounds when heated to extremely high temperatures; porcelain

Evaporating Dish

Evaporating Dish

Heats and evaporates liquids; used for sublimation set-up

Beaker

Beaker

Used to hold and heat liquids; multipurpose; least accurate for measuring volume; mostly for storing liquids

Pipette

Measures volume of liquid; used with aspirator

Erlenmeyer Flask

Best receiver for filtration, distillation, and titration set-ups; holds distillate from condenser

Volumetric Flask

Measures one specific predetermined volume; used for accurate solution preparation

Graduated Cylinder

Accurately measures liquid volume; not used as a container

Burette

Measures precise liquid delivery in titrations

Triple Beam Balance

Measures mass precisely; error ±0.05 g; used with weighing boat

Analytical Balance

Most precise balance; measures to 0.0001 g; very sensitive; must be on stable surface

Top Loading Balance

Measures objects from ~150–5000 g; less accurate than analytical balance

Weighing Boat

Holds samples while weighing

Pasteur Pipette

Transfers small amounts of liquid; for smaller volumes

Glass Pipette

Longer for greater volume transfer; more accurate

Glass Funnel

Transfers liquids between containers or for filtration with filter paper

Buchner Funnel

Vacuum-assisted filtration; removes moisture; part of filtration set-up

Separatory Funnel

For liquid-liquid extractions; separates immiscible liquids

Porcelain Spatula

Takes small amounts of powdered compounds; resists corrosion

Stainless Spatula

Scrapes, transfers, or applies powders/pastes

Rubber Policeman

Removes precipitates from glassware
