Common Laboratory Equipment

Beaker

Running reactions, mixing chemicals, heating chemicals

Filter Flask

Used in vacuum filtration

Watch Glass

Holding chemicals, covering beakers during heating

Dropper Pipets

For adding small amounts of chemicals - usually by drops

Graduated Glass Pipets

Is used to accurately measure liquids. ALWAYS USE A BULB. They add varying amounts of liquids.

Volumetric Glass Pipets

Is used to accurately measure liquids. ALWAYS USE A BULB. They add the specified amount.

Buret

Accurately measuring/delivering liquids

Round Bottom Flask

Running reactions, heating chemicals, mixing chemicals - easier for mixing than beakers

Graduated Cylinder

Used for accurately measuring the volume of liquids

Glass Stirring Rod

For stirring chemicals

Buchner Funnel

Funnel used for vacuum filtration

Polywash Bottle

Used to add chemicals or used to add solvents for cleaning of beakers and other glassware

Erlenmeyer Flask

Running reactions, heating chemicals, mixing chemicals - easier for mixing than beakers

Volumetric Flask

Used to mix chemicals to accurately determine concentration

Test Tube

Used for mixing and heating chemicals and running reactions - smaller quantities than beakers and flasks

Evaporating Dish

Used to evaporate liquids

Scoopula

A laboratory tool used for transferring small amounts of solid substances. It typically consists of a metal or plastic handle with a spoon-shaped end, allowing for easy scooping and transferring of materials.

Test Tube Holder

It securely holds ________ in a lab. It has an adjustable clamp or spring mechanism for different sizes. It ensures safe handling during experiments or when heating over a flame.

Forceps

“Tweezers” that are used for gripping and manipulating small or delicate objects

Funnel

Used for filtering and for adding chemicals without spilling

Spatula

Are utensils that help with mixing, scraping, and other tasks related to transferring materials and samples from one place to another.

Analytical Balance

Are precision measuring instruments used in quantitative chemical analysis, to determine the mass of solid objects, liquids, powders and granular substances.

Pipet pumps

They are used for transferring precise volumes of liquid into a glass pipet.

Hot Plates

They are used to perform chemical reactions, to heat samples, and for numerous other activities. ______ are conceptually simple – a flat surface with heating elements.

Bunsen Burner

A type of gas burner commonly used as a heat source in laboratory experiments.

Wire Brush

Are typically designed with a wire handle and nylon bristles. These brushes are used for cleaning bottles, pipettes, burrettes, beakers, graduated cylinders, flasks, and glass test tubes.

Rubber Stoppers

Are used to plug flasks and test tubes. The purpose of them is to prevent liquids, and sometimes gases, from escaping their containers, as well as prevent contaminants from entering the containers.
