what is a scoop/scoopula/spatula? what is it used for?

A spatula/scoopula/scoop is a utensil used to transfer and distribute dry chemical compounds; they are used to weigh out chemicals on a balance most often, as they allow one to collect small quantities of a substance at a time.

what is a stirring rod? what is it used for?

A stirring rod is a piece of laboratory equipment, generally made of thick glass, used to mix chemical substances.

what is a test tube brush? what is it used for?

A test-tube brush is used for cleaning test tubes and other laboratory equipment with narrow openings, such as graduated cylinders or Erlenmeyer flasks.

what is a volumetric pipet? what is it used for?

A volumetric pipet can be used to make laboratory solutions from a base stock or prepare solutions for titration by allowing immensely accurate measurements of said solutions's volumes to be taken.

what is wire gauze? what is it used for?

A wire gauze is a thin sheet of metal with net-like patterns of wire mesh; it can be placed on the support ring attached to the retort stand between a Bunsen burner and glassware in order to support beakers, flasks, or other equipment during heating.

what is an erlenmeyer flask? what is it used for?

An Erlenmeyer flask is a glass container that has a narrow, cylindrical mouth and a cone-shaped main body, ending in a wide, flat bottom. It can be used to mix or store chemical solutions or substances.

what is an electronic balance? what is it used for?

An electronic balance is a device used to find accurate measurements of different substances' weights.

what is an evaporating dish? what is it used for?

An evaporating dish is a type of glassware used for the evaporation of solutions and supernatant liquids; they essentially evaporate excess solvents, producing either a concentrated solution or solid precipitate of the dissolved solution.

what are crucible tongs? what are they used for?

Crucible tongs are scissor-like tools, but instead of having two blades, these tools are replaced with two pincers, or pieces of metals that concave together. They allow users to grasp a hot crucible, flasks, evaporating dishes, or even small beakers while performing an experiment.

what are forceps/tweezers? what are they used for?

Forceps/tweezers are used to grab small items that one's own fingers cannot.

what is a thermometer? what is it used for?

In chemistry laboratories, thermometers are devices used for measuring substances' temperatures in a variety of circumstances; they can measure solids', liquids', and gases' temperatures, and can read them back based on a Celsius, Fahrenheit, and/or kelvin scale.

what is a rubber stopper? what is it used for?

Rubber stoppers are used to plug joints or holes in different types of laboratory glassware, such as test tubes or flasks, and create a liquid-tight seal so that none of the equipments' contents spill out.

what is rubber tubing? what is it used for?

Rubber tubing is essentially used to contain and transport various fluids and gases; it is commonly utilized in flow lines for gases and fluids in a variety of applications, including with Bunsen Burners in chemistry laboratories.

what are safety goggles? what are they used for?

Safety goggles are a form of protective eyewear that enclose and protect the eye and its surrounding area from water or chemical substance penetration.

what is a test tube? what is it used for?

Test tubes are used to handle chemical substances, as well as to heat small amount of liquids or solids with a Bunsen burner.

what is a test tube holder? what is it used for?

Test-tube holders are used for holding test tubes in place if they are hot, being heated, or should not be touched in general.

what is a test tube rack? what is it used for?
