What are the names and uses of the various kinds of laboratory apparatus used in biology?
A round, shallow, flat dish with a loose cover made of glass or
plastic. It can be used for growing cultures (such as bacteria,
animal, plant, fungal, etc) and seed germination, as well as for
other applications. Petri dishes may be reused if sterilized. It is
named after German bacteriologist Julius Richard Petri.
Are used for staining in pathology, microscopy, microbiology and
hematology. These dishes can be made of plastic, stainless and
glass. The racks hold slides made of glass. The jars are used for
actually staining the slides or as a development chamber.
Staining is a biochemical technique of adding a
class-specific (DNA, proteins, lipids, carbohydrates) dye to a
substrate to qualify or quantify the presence of a specific
compound. It is similar to fluorescent tagging.
Example: Gram Staining: a technique for identifying/classifying
Used for mounting tissue/specimen for observation.
AKA Cover Slides, these are smaller sheets of glass used to
cover the slide after specimen has been mounted. A cover slip
flattens the object and also acts as a barrier, keeping the
microscope's lens clean. Additionally, it slows the evaporation
from the surface of the slide that is being examined.
Cell incubators are used to grow maintain
cultures/organisms/objects at a fixed temperature and humidity. The
application or use determines the optimal temperature to be
Sterilization devices that achieve sterilization via
pressurization and increased temperatures, heating sterilizing
solutions above boiling points in order to sterilize medical and
lab instruments. Autoclaves are used in the medical field and
tattoo and body piercing parlors, as well as the manufacturing
industry to "cure" products during certain manufacturing
The autoclave was invented by Charles Chamberland in 1879.
A cylindrical glass "tubing" that is open at the top and
U-shaped at the bottom that is used to contain materials under
observation. A mild rule of thumb distinction is often made between
a test tube and a culture tube. The test tube has a rounded lip at
the top. The culture tube has no lip. These terms continue to be
When heating materials such as with a Bunsen burner, it is best
to use a boiling tube as these are made to withstand the higher
Test Tube Holders:
Are obviously made to hold a test tube (or culture tube or
boiling tube). These can be made out of wood or metal racks and can
hold other items such as pipettes.
Are small gas burners used to heat materials for experiments.
Its flame is adjustable at the base of the burner by controlling
the amount of gas/air. The gas is controlled via valve to the gas
container and the "flue" is used to control the amount of air via
holes at the bottom of the burner.
In short, it is a shallow, concave glass dish that can be used
as a beaker cover or an evaporating surface, so named because they
look like the glass on the front of the old pocket watches used by
train conductors and such.
Microscope usually compound microscope.
Dissection box or dissecting instrument such as forceps, knife,
needle, bone cutter etc.
