10 Laboratory Apparatus And Their Use?

For most people, the term laboratory conjures up thoughts of chemistry or biology. The following list of items is therefore mainly geared towards this line of thought:

1. Microscope
2. Beaker
3. Bunsen burner
4. Balance
5. Test tube
6. Multimeter
7. Graduated cylinder
8. Evaporating dish
9. Pipette
10. Distillation apparatus

Uses:

1. A microscope allows users to view anything too small for the human eye to discern.

2. Beakers are used to hold samples, contain limited chemical reactions or catch liquids produced during experiments.

3. Bunsen burners provide an adjustable, direct source of heat for experiments.

4. Balances are used to determine the mass of various substances, such as dry chemicals, for example.

5. Test tubes are generally used to hold samples or provide small vessels for chemical reactions. Test tube holders allow test tubes to be held safely if heating is required for an experiment.

6. Experiments involving electronics or electricity usually include a multimeter. A multimeter is able to measure voltage, alternating (AC) or direct (DC) currents and resistance.

7. Graduated cylinders are fairly slim plastic or glass cylinders, used to calibrate beakers or measure liquids. Sizes range from 10, 25, 50 and 100 ml to 500 or 1000 ml.

8. Evaporating dishes, usually quite shallow and equipped with a lip to facilitate pouring, are used to heat and evaporate liquids. This type of experiment can be used to concentrate a liquid.

9. Pipettes are used to transfer small amounts of liquid. The amount which can be drawn into a pipette is typically fixed, enabling accuracy of measurement.

10. A distillation apparatus is used to separate a particular portion of a fluid by heating liquid to the point where a desired compound evaporates. The resulting gas is fed through a downward-angled cooling tube, at the bottom of which the re-condensed fluid compound is collected.

# Laboratory apparatus will vary from lab to lab depending on the lab's expense and sophistication, and the nature of the experiments done there. Although a high school physics and chemistry lab will not have the same high-tech equipment that a biomedical research lab at the National Institute of Health has, most labs do share common categories of tools, such as measuring and safety equipment.
Safety Equipment
# All labs will have safety equipment. Most will possess eye goggles, which protect a scientist's eyes from chemical spills, debris and irritating gases. Some labs will also have eye-washing stations, essentially sinks with a faucet on opposite ends. Gloves are another common safety item. These can protect the hands against extreme temperatures or very acidic or basic substances, depending on the make of the glove.
Measuring Equipment
# Graduated cylinders are common features of a lab's measurement tool inventory. This item is a tall cylinder with a stabilizing base and marks up the side that indicate volume measurements for liquids or for irregular objects. Small irregular objects are measured by displacement, measuring the difference between the starting level of the liquid they are placed in and the level after the object has been put in the cylinder. Another measuring device not found in most simple labs is a volumenometer, which also measures the volume of irregular objects. However, it measures things that could be damaged when placed in liquids, such as fragile roots.
Viewing Small Objects
# Magnifying lenses allow scientists to look at small objects in more detail. Microscopes do the same thing and to a greater extent. These tools can ranger in price for a few bucks to tens of thousands of dollars. A magnifying glass may be used to look at an insect's wing structure, while a microscope at 1000x magnification could look at the structure of the individual cells in those wings.
