Beaker
Function:
Provides an approximate measurement of a liquid’s volume in liters (L) or millimeters (mL).
Graduated Cylinder
Function:• Measures the
volume of liquid in mL
• The liquid is measured at the meniscus (curved surface of the water)
Florence or Erlenmeyer Flask
Function:• Container for
chemicals• Measures volume• Cylindrical neck
allows
liquids to be swirled
Petri Dish
Function:• Allows the growth and
observation of organisms
• Looks like a clear shallow dish with a lid
• Can be plastic or glass and cleaned for repeated use.
Test Tube Clamp
Function:• Holds the test
tube • Used when the
test tube contains dangerous or hot chemicals
Thermometer
Function:• Measures temperature• Measurements reported
in degrees Celsius • We use thermometers
with alcohol, not mercury.
Microscope
Function:• Uses objective
lenses to magnify small objects for observation
• Magnifications can vary
Stereoscope
Function:• Also called a
dissecting microscope
• Able to zoom in on an object for closer observation or dissection
Eyedropper
Function:• Transfers a small
amount of liquid volume (drop by drop) by squeezing and releasing the bulb
Dissecting Equipment
Function:• Helps to cut, observe,
transfer, and examine biological specimens.
• Includes: probe, scissors, scalpel, tweezers, pins
• NOTE: You need to know images for a Scalpel, Probe, Forceps, and Dissecting scissors individually.
Lab Incubator
Function:• Device used to grow and
maintain microbiological cultures
• Maintains optimal temperature and humidity
Task:
What would happen if you put a petri dish containing bacteria into an incubator?
Biological Specimen
Function:• Preserved
biological organism or object
• Used for biological research and observation
Microscope Slides
Function:•Thin flat piece of glass used to hold objects in place under a microscope.
Ring Stand
Function:• Allows for
attachment of clamps to suspend test tubes, flasks, wire gauze and clay triangles.
