Laboratory Equipment

Comprehensive vocabulary list of common laboratory equipment and their specific functions as described in the lecture transcript.

Apron

Equipment that shields the wearer's clothing and skin from chemical splashes and spills during an experiment.

Safety Goggles

Protective equipment that protects the eyes from chemicals and splashes.

Beaker

Used for mixing, stirring, and heating chemicals, but is not a precise instrument for measuring volume.

Beaker Tongs

Used to move beakers containing hot liquids.

Bunsen Burner

An apparatus that produces an open flame used for the heating of liquids and solids.

Buret

Dispenses known volumes of liquids, especially in an acid-base titration.

Buret Clamp

A device used to hold and secure a buret on a ring stand.

Clamp

Used to hold and secure an apparatus on a ring stand.

Clay Triangle

A support for crucibles when they are being heated over a Bunsen burner.

Cleaning Brush

Used for cleaning the inside of laboratory equipment.

Crucible and Cover

Used to heat solids, particularly metals, to a very high temperature.

Crucible Tongs

Used for handling hot crucibles and picking up other hot objects, but should not be used for picking up beakers.

Electronic Balance

Precisely measures the mass of an object using sensors and a digital display; chemicals should never be placed directly on it and require a weigh boat or paper.

Erlenmeyer Flask

A piece of glassware used for mixing, heating, and storing liquids, but not as an accurate measurement for volume.

Evaporating Dish

Separates liquids and solids in a solution through the process of evaporation.

Forceps

Also known as tweezers, these are used to pick up small objects.

Funnel

Used to channel liquids into containers with narrow openings to prevent spills and splashes; also used when filtering.

Glass Stirring Rod

A rod used to manually stir solutions.

Graduated Cylinder

Used to accurately measure the volume of liquids in milliliters ($mL$).

Hot Plate

Provides a controlled heat source to heat samples.

Iron Ring Clamp

Used to stabilize flasks and other glassware above the work surface.

Mortar and Pestle

Used to prepare solid substances by crushing and grinding them into a fine paste or powder.

Ring Stand

A stand that holds or clamps laboratory glassware and other equipment in place.

Scoopula

A tool used to scoop up and transfer solids.

Test Tube

Holds small amounts of material for a reaction or for heating.

Test Tube Tongs

Used to hold a test tube, especially when heating it.

Test Tube Rack

Supports and stores test tubes during an experiment.

Thermometer

Used to precisely measure the temperature of substances.

Transfer Pipet

Used to transfer small amounts of liquid drop-wise.

Volumetric Flask

Contains or measures a very precise and accurate amount of liquid; typically used for preparing solutions of an exact concentration.

Wash Bottle

Dispenses distilled water for cleaning glassware and rinsing; should never be filled with tap water.

Watch Glass

Used for evaporation, holding small amounts of liquids or solids, or used to cover beakers.

Well Plate

A flat tray used to perform many small scale reactions at one time.

Wire Gauze

Supports glassware on top of the iron ring clamp while heating.
