Biology quiz

Also called a smear loop, inoculation wand or microstreaker, is a simple tool used mainly by microbiologists to retrieve an inoculum from a culture of microorganisms.

inoculating loop

A thin cylinder containing many markings. Used to measure liquids with moderate precision.

graduated cylinder

Glove-like sleeve made of a rubbery and thermally insulating polymer. Used to handle hot glassware.

hot hands

A portable self-contained tabletop small appliance that features one, two or more electric heating elements or gas burners.

hot plate

Form of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the

safety googles

A knife with a small, sharp, sometimes detachable blade, used during laboratory dissections and by surgeons.

scalpel

A stand with a wide metal base and a single metal rod. Clamps and clamp holders attach to the rod.

ring stand

Mainly used in chemical laboratory in combination with flasks and test tube

rubber stoppers

A flexible hollow tube designed to carry fluids or gases from one location to another.

rubber tubing

A cylindrical piece of glassware with coarse markings. Used to hold liquids, but should not be used for measurements of volume where precision is needed.

Beaker

A metal tube with two valves and an inlet for natural gas. The valve on the base controls the flow rate of gas; the valve on the side controls the amount of oxygen in the gas mixture.

Bunsen burner

A tapered flask with an opening thinner than the base and coarse volumetric markings. Erlenmeyers are used to hold liquids but should not be used for measurements of volume where precision is needed

Erlenmeyer flask

A long, thin cylindrical piece of glassware with a stopcock on one end. Used to deliver liquids with very high volumetric precision.

buret

A funnel containing a relatively thin nozzle that fits into the top of a buret. Used to deliver liquids without making a mess.

buret funnel

Used in conjunction with a ring stand to hold equipment in place. A clamp holder screws into both the ring stand and the clamp.

clamp

A triangular device made of heat-resistant clay. Used to hold crucibles and porcelain dishes heated by a Bunsen burner. Distributes heat evenly over the surface of objects it holds.

clay triangle

A thin flat piece of transparent material, usually square or rectangular, about 20 mm (4/5 in) wide and a fraction of a millimetre thick, that is placed over objects for viewing with a microscope.

coverslip

used to pin specimens during a classroom dissection project.

dissecting pins

Used to tease and separate specimens, pin body parts, and explore dissected animals.

dissecting probe

a pair of scissors that is used in a classroom setting for dissections or in medical and surgical settings.

dissecting scissors

A tray that provides containment for materials resulting from the dissection process.

dissection tray

A short glass tube with a rubber bulb at one end and a tiny hole at the other, for measuring out drops of medicine or other liquids.

dropper

A device used to find accurate measurements of weight. It is used very commonly in laborites for weighing chemicals to ensure a precise measurement of those chemicals for use in various experiments.

electric balance

Paper stained with litmus, used to indicate the acidity or alkalinity of a substance. Blue litmus paper turns red under acid conditions, and red litmus paper turns blue

litmus paper

A convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle

magnifying glass

An optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.

microscope

A thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope.

microscope slide

A shallow cylindrical glass or plastic lidded dish that biologist use to culture cells--such as bacteria--or small mosses.

petri dish

A funnel containing a relatively wide nozzle. Used to deliver solids without making a mess—essential in precise preparation of solid-liquid solutions.

powder funnel

A piece of laboratory equipment used to mix chemicals and liquids for laboratory purposes.

stirring rod

A piece of flint held inside a small bowl and attached to a metal piece that can be rapidly slid across the flint to create a spark. Used to light Bunsen burners.

striker

A device consisting of a narrow tube fitted at one end with a rubber bulb or piston by means of which a liquid can be drawn in and then ejected in a stream.

syringe

A tube-shaped piece of glass used to hold liquids and solids for observation. Comes in small, medium, and large sizes. Don't fill more than three-quarters full if you're being careful.

test tube

a brush used for cleaning test tubes and narrow mouth laboratory glassware--such as beakers and flasks.

test tube brush

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

test tube holder

A laboratory equipment that is used to hold upright multiple test tubes at the same time.

test tube rack

A device that measures temperature or a temperature gradient.

thermometer

An instrument with two movable arms that are joined at one end, used for picking up and holding things.

tongs

An instrument used to measure mass very precisely. The device has reading error of +/- 0.05 gram.

triple beam balance

A handheld, hinged instrument used for grasping and holding objects.

tweezers(forceps)

A round flask with a long, thin opening bearing one mark. The mark corresponds to the volume indicated on the flask. Used to prepare solutions and measure liquids very precisely.

volumetric flask

A bottle made of flexible plastic with a thin, angled nozzle. Used to hold liquids (usually water) for spraying or delicate delivery. Useful for adding that last bit of liquid during solution preparation in a volumetric flask.

wash bottle
