Chem181: Activity 1

Acid Burette

It is a laboratory equipment used in analytical chemistry for the dispensing of variable amount of a chemical solution and measuring that amount at the same time.

A glass vial with graduation marks. It is used in the laboratory for accurately measuring and dispensing liquids.

Adapter

It is a laboratory equipment used to connect pieces of ground glass joint glassware to each other, to a vacuum source, or to a water aspirator. It is also used to lead liquids from a condenser to a receiving flask during distillation.

Alcohol Lamp

It is piece of laboratory equipment used to produce an open flame. It is usually made of glass but can also be made of brass, aluminum or stainless steel.

It is otherwise called as alcohol burner or spirit lamp.

Alkali/Base Burette

It is a laboratory equipment used in analytical chemistry for the dispensing of variable amount of a chemical solution and measuring that amount at the same time.

Are used for base titrants. Basically, this is used in titrations where the analyte is an acid.

Beaker

It is a cylindrical borosilicate glass container used as a receptacle for solid and liquid substances.

Bunsen Burner

It is used as a heating device in laboratory experiments.

Clay Flame Shield

It is a heat resistant apparatus used to insulate the Bunsen burner flame from the surroundings. It is also used to support materials when heating.

Clay Triangle

It is a piece of laboratory equipment used in the process of heating substances. It is used in conjunction with the clay shield to create a stable framework in which to place a substance -- usually a solid chemical -- while it is heated to a high temperature.

Condenser

It is a device used in the laboratory to condense hot vapors into liquids during distillation.

Crucible Tong

It is used to safely handle hot materials at very high temperatures.

Digital Balance

It is an electronic instrument used to weigh objects and small amounts of substances up to the milligram level.

Distilling Flask

It is a piece of laboratory equipment that is used to separate mixtures of two liquids with different boiling points.

Dropper

It is used to transfer small quantities of liquids.

Erlenmeyer flask

It is an apparatus used for the storing and mixing of chemicals in a laboratory setting.

Evaporating Dish

It is a piece of laboratory glassware used to evaporate excess solvent in a solution- most commonly water- to produce a concentrated solution or a solid precipitate of the dissolved substance

Florence Flask

It is a type of flask designed for uniform heating, boiling, distillation, and ease of swirling.

Funnel

It is used to channel liquid or fine-grained substances into containers with a small opening.

Glass Rod/ Stirring Rod

It is used to mix chemicals and liquids for laboratory purposes.

Glass Tubing

It is a hollow tube made of glass that is used to connect other pieces of lab equipment.

Graduated cylinder

It is used for measuring volumes (amounts) of liquids accurately.

Iron Clamp

It is piece of laboratory equipment that is used to hold things in place.

Iron Ring

It is used to hold or support beakers during experiments while connected to the iron stand.

Iron Stand

It is used to supports the iron ring when heating substances or mixtures in a flask or beaker.

Pipette

It is a calibrated laboratory apparatus used to transfer a measured amounts of liquid from one container to another.

Pipettor

It is used to draw liquids in pipettes.

Test tube

It is used for heating small amounts of liquids or solids with a Bunsen burner or alcohol burner and is used for reacting substances.

Test tube brush

It is a brush used for cleaning test tubes and narrow mouthed laboratory glassware such as beakers and flasks.

Test tube clamp

It is attached to an iron stand and used to hold test tubes in place during heating operations and/or reactions

Test tube holder

It is used for holding a test tube in place when the tube is hot or should not be touched.

Test tube rack

It is used to hold upright multiple test tubes at the same time. It is most commonly used when various different solutions are needed to work with simultaneously, for safety reasons, for safe storage of test tubes, and to ease the transport of multiple tubes.

Thermometer

It is used to measure temperatures or temperature changes with a high degree of precision.

Water Bath

It is used to incubate samples in water at a constant temperature over a long period of time. It is also used to enable certain chemical reactions to occur at a controlled temperature.

Wash Bottle

It is a bottle with a nozzle that can be easily squeezed. It is used to rinse various pieces of laboratory glass wares.

Watch Glass

It is used to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker.

Wire Gauze

It is placed on the support ring that is attached to the retort stand between the Bunsen burner and the beakers in order to support the beakers or other glassware or flasks during heating.
