Lab Equipment Magnifying glass Used to examine objects

Lab Equipment…

Magnifying glass • Used to examine objects in greater detail than the unaided eye allows

Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.

Erlenmeyer Flask Erlenmeyer flasks hold solids or liquids that may splatter if stirred or heated.

Graduated Cylinder A graduated cylinder is used to measure volumes of liquids. • ALWAYS measure from the meniscus

Lab Safety Goggles • Used to protect your eyes from chemicals and dangerous objects such as broken glass

Test Tube and Test Tube Holder A test tube is used to keep large numbers of samples in one place A test tube holder is useful for holding a test tube which is too hot to handle.

Test Tube Racks Are used to hold and store the test tubes

Bunsen Burner • Used to start a flame.

Florence flask • It can be used as a container to hold solutions of chemicals. A Florence flask has a round body with a single long neck and with either a round or a flat bottom.

Pipette • Use to draw liquids and dispense.

Test Tube Brushes Test tube brushes are used to clean test tubes and graduated cylinders. Forcing a large brush into a small test tube will often break the tube.

Medicine Dropper A medicine dropper is used to transfer a small volume of liquid (less than one m. L). On top of each medicine dropper is a “rubber bulb”

Forceps (or tweezers) are used to pick up small objects.

Funnel A funnel is used to aid in the transfer of liquid from one vessel to another.

Metric Rulers • Used for measuring length of objects.

Triple Beam Balance • Used to measure the mass of an object

Cutting tools • Scissors Use to cut • Scalpels

Dissecting Probes • Used to open, manipulate, or hold samples that may be dissected or examined.

Dissecting pins • Used to pin down specimen for dissecting.

Dissecting Pan • Used to keep the things we cut up in one place, and to minimize mess

Thermometers • Used to determine temperature

Compound Light Microscope • Used to examine items or objects too small for the unaided eye

Petri Dishes • Used to grow microorganisms, usually with agar of some type

Microscope slides and cover slips • Used to examine samples under a microscope Microscope Slide Cover slip
