They are used to measure, observe and gather data for experiments, as well as to safely perform reactions and to heat things. More advanced laboratory equipment includes items such as spectrometers, centrifuges and chromatographs.
Of utmost importance are these safety tools:
Tools and their uses:
For more information on these tools, see the Related Questions and the Related Links.
Petri Dish:
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.
Staining Dishes:
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. (http://en.wikipedia.org/wiki/Staining_(Biology)
Example: Gram Staining: a technique for identifying/classifying bacteria.
Glass Slides:
Used for mounting tissue/specimen for observation.
Cover Slips:
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.
Incubators:
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 used.
Autoclaves:
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 processes.
The autoclave was invented by Charles Chamberland in 1879.
Test Tubes:
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 used interchangeably.
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 temperatures.
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.
Bunsen burner:
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.
Watchglass:
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.
Pipettes
Any tool or instruments which are used in a laboratory. This might include beakers, microscopes, tweezers, hot plates, lasers, volt meters, test tubes, or any number of other things you'd find in a laboratory! Here's my answer: Laboratory apparatus are tools or instruments used inside a laboratory and it helps the person in the laboratory to make experiments....
this is an instrument in the laboratory that is used to clean various kinds of test tubes.
Cellular biology would cover cells of various kinds and their parts and how they work. Anatomy is the study of a body. This can be any kind: human, frog, cat, etc.
A laboratory is a place where people do science and other kinds of shenannigans.
because you learn about the differnt kinds of animals and their characteristics which you can only learn in biology

There are dozens of different laboratory jobs out there, to name a few of the more general ones there would be clinical laboratories, medical laboratories, chemistry laboratories, forensic laboratories, general laboratories and biology laboratories.

The laboratory apparatus have different materials because of different types of experience... If you look at a beaker or text tube, it definitely have to be glass why? So that you can see the reaction through the glass and when heated it will not melt in the case of making them plastic. The metal in stands is because metal is more firm and can be easily adjusted unlike wood which can not be use for metallic functions.

In biology, the dependent variable is the factor being measured or tested in an experiment, and its value depends on the independent variable. The independent variable is the factor that is manipulated or controlled by the researcher to observe its effect on the dependent variable. For example, if studying the effect of different fertilizer amounts (independent variable) on plant growth, the plant growth measurements would be the dependent variable.
