LABORATORY APPARATUS AND SET-UP

Erlenmeyer Flask

It used to heat or boil substances over a Bunsen burner flame or hot plate.

Dropper

Used for moving small amounts of liquid from place to place. They are usually made of plastic and are disposable.

Weighing Boat

Used as a container for dry chemicals prior to weighing

Spatula

Used to draw dry chemicals from the reagent bottles. Used for moving small amounts of solid from place to place.

Mortar and Pestle

A tool used to grind substances.

Beaker

A simple container for liquids, very commonly used in laboratories

Graduated Cylinder

A piece of laboratory glassware used to accurately measure volumes of chemicals for use in reactions

Glass Funnel

It can be used to target liquids into any container so they will not be lost or spilled.

Büchner funnel

It is used in suction filtration.

Test Tube Brush

It is used mainly for cleaning test tube

Test Tube

A clear, cylindrical glass tube usually open at one end and rounded at the other, used in laboratory experimentation

Test Tube Holder

Used to hold test tubes while reactions happen in them or while they are not needed.

Iron Ring

Used to hold items being heated and can be used so that items may be placed above the lab table for heating by bunsen burners or other items.

Watch Glass

A circular, slightly concave piece of glass used in chemistry as a surface to evaporate a liquid, or as a cover for a beaker and used to hold solids when being weighed or transported. They should never be heated.

Evaporating Dish

It is used to heat and evaporate liquids.

Crucible Tong

Used to hold glasswares when they are hot and untouchable

Beaker Holder

Used to hold glasswares when they are hot, untouchable

Test Tube Holder

Used to hold glasswares when they are hot and untouchabl

Tripod

Three legged platform made of stainless steel or aluminum used to support flasks and beakers. Often a wire gauze is placed on top of the tripod to provide a flat base for glassware.

Clay Triangle

Used to hold crucibles when they are being heated. They usually sit on a tripod.

Iron Clamp

A piece of laboratory equipment used to hold things and is placed in an iron stand to elevate other equipment

Thistle Tube

A piece of laboratory glassware consisting mostly of a shaft of tube, with a reservoir and funnel-like section at the top. It is used by chemists to add liquid to an existing system of apparatus.

Water Bath

A laboratory equipment made from a container filled with heated water. It is used to incubate samples in water at a constant temperature over a long period of time.

Hot Plates

It is generally used to heat glassware or its contents. Some also contain a magnetic stirrer, allowing the heated liquid to be stirred automatically.

Alcohol Lamp

It is used to produce an open flame. Their flame is limited to approximately 5 centimeters (two inches) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner.

Bunsen Burner

It is named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion. The gas can be natural gas or a liquefied petroleum gas.

Wingstop or Fishtail

It spreads out the heat in the Bunsen burner over a large area. Used to bend glass in glass manipulation process.

Tirril Burner

An air and gas device much like the Bunsen, but with extra adjustments that provide for better temperature control and flame size and has a gas regulator

Meker-Fisher Burner

A laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion. It is used when laboratory work requires a hotter flame than produced by a Bunsen burner.

Stirring Rod

Used for mixing liquids or solids and liquids

Glass Tubing

It is used to connect other pieces of lab equipment. It can be cut, bent and stretched for a variety of uses.

Rubber Tubing

It is often connected to a condenser, which is a laboratory tool used in the process of distillation. It helps cool water to flow in and out of the condenser and helps the heated water vapor in the condenser return to its liquid state.

Adapter

Used in a distillation set-up. It connects to the lower end of the condenser and serves to direct the distilled liquid into the receiving flask.

Thermometer

Used to take temperature of solids, liquids, and gases. They are usually in Celcius.

Pasteur pipette

It is also known as droppers or eye droppers, are used to transfer small quantities of liquids. They are usually glass tubes tapered to a narrow point, and fitted with a rubber bulb at the top. The combination of the Pasteur pipette and rubber bulb has also been referred to as a teat pipette.

Triple Beam Balance

An instrument used to measure mass very precisely. The device has reading error of +/- 0.05 gram. The name refers to the three beams including the middle beam which is the largest size, the front beam which is the medium size, and the far beam which is the smallest size.

Gas Collection

Extraction

Evaporation

Sublimation

Distillation
