Commonly Used Lab Equipement Quiz

Rubber stoppers are commonly used in laboratories to securely seal flasks and test tubes to prevent any leakage or contamination. Cork, aluminum foil, and plastic wrap are not typically used for this purpose.

Test tubes are commonly used in laboratories for various purposes such as mixing, heating, or storing substances. Bunsen burners are used for heating, microscope slides are used for viewing samples under a microscope, and pH paper is used to measure the acidity or alkalinity of a solution.

A test tube rack is specifically designed to hold multiple test tubes in an upright position for easy access and organization during experiments.

A test tube holder is specifically designed to hold a test tube securely while it is being heated, ensuring the safety of the user. Beaker, pipette, and Bunsen burner are all lab equipment but are not designed for holding a hot test tube.

Test tubes are best cleaned using a specialized cleaning tool known as a test tube brush, which is designed to effectively scrub the narrow, cylindrical shape of the test tube.

A Petri Dish is a shallow, flat, round glass or plastic dish with a loose-fitting cover used to hold specimens for observation and to grow cultures. Beakers are used for measuring liquids, test tubes are used for holding small amounts of liquid, and microscope slides are used to hold thin samples for observation under a microscope.

A funnel is a specially designed tool for directing liquids into containers without spillage, making it the correct answer. A sponge, strainer, and whisk are not typically used for pouring liquids into small openings.

A meter stick is the correct instrument for measuring length in the Metric System. While rulers, tape measures, and yardsticks can also measure length, they are not specifically calibrated for the Metric System like the meter stick.

An eye dropper is a small, glass tube with a rubber bulb at one end that is used to measure and transfer small amounts of liquids accurately.

The correct answer is Triple Beam Balance, as it is specifically designed to measure the mass of an object in grams. Ruler is used for measuring length, thermometer is used for measuring temperature, and graduated cylinder is used for measuring volume.

A thermometer is specifically designed to measure temperature, while a barometer measures atmospheric pressure, a compass provides direction, and a ruler is used for measuring length or distance.

Safety goggles are specifically designed to protect the eyes from various hazards, such as chemicals or flying debris. Sunglasses, reading glasses, and 3D glasses do not provide the same level of protection for the eyes in hazardous situations.

A compound microscope is specifically designed to magnify small objects by using two lenses placed near the object. Binoculars, magnifying glasses, and telescopes all use lenses to magnify objects as well, but they typically use only a single lens or a combination of mirrors and lenses.

Cover slips are thin and transparent pieces of glass used to protect the specimen on a microscope slide while allowing light to pass through for observation.

A glass slide is the most common surface used to place specimens on for observation under a microscope. Petri dish, cover slip, and microscope slide are not typically used for directly observing specimens under a microscope.

A magnifying glass is a single lens that can be used to make objects appear larger. While microscopes and telescopes also use lenses, they differ in their purpose and design. Cameras may use lenses, but they do not make objects appear larger in the same way a magnifying glass does.

A hot plate is a portable electric device used for heating up things by using a heating element. The other options listed are also electrical devices but serve different purposes - a toaster is used for toasting bread, a hair dryer is used for drying hair, and an electric blanket is used for keeping warm.

A graduated cylinder is specifically designed for accurate measurement of liquid volume in milliliters. Beakers and Erlenmeyer flasks are not as precise as graduated cylinders, and pipettes are used for transferring known volumes of liquids, not measuring volume directly.

A beaker is the most commonly used piece of glassware in the laboratory for general purposes. While Erlenmeyer flasks, graduated cylinders, and test tubes all have their specific uses, they are not typically used for the same combination of tasks as a beaker.

Beaker tongs are specifically designed to safely handle hot beakers in the laboratory. Bunsen burners are used for heating, pipettes for measurement, and mortar and pestle for grinding and mixing substances.

The Florence Flask is specifically designed for heating and storing substances, resembling a potion glass. Beakers, test tubes, and Erlenmeyer flasks are commonly used in laboratories but serve different purposes.

The Erlenmeyer Flask is specifically designed to be heated over an open flame and is commonly used in chemistry laboratories for heating and storing substances. Beakers, test tubes, and graduated cylinders are also common glassware in laboratories but are not primarily used for heating substances.
