Laboratory equipment makes sophisticated testing and product development possible. Knowing some of the key terms associated with laboratory equipment will help ensure that you and your staff use the proper equipment for the job at hand. Although you may use only a few types of laboratory equipment during the course of a workday, knowing the basic key terms of some other types can help you to think outside the box when new projects come up.
EudiometerAn eudiometer is a graduated glass tube used to measure reactions of gases. Some are curved, while others are straight. Many eudiometers have electrical charge connections.
PycnometerA pycnometer is a density analyzer that can measure very small bits of matter. Most pycnometers use a method called the Gas Displacement Technique.
U.S. Department of Energy and the University of California, Santa Barbara offer information about pycnometers.
Bunsen burnerA Bunsen burner is an open-flame heat source used in laboratories to do experiments. It uses a mixture of methane and oxygen to produce the flame when ignited. Adjusting the air control vent changes the mixture, which changes the intensity of the flame.
SpectrophotometerA spectrophotometer is a device that measures the change in the intensity of light through various substances and densities. The machine uses a spectrometer, which produces light in any color, and a photometer, which measures the intensity of the light.
Rice University offers an in-depth explanation of the spectrophotometer. Instructions are included for using one of the most common spectrophotometers. Also included is an explanation of why you should use a reference solution with the spectrophotometer.
CalorimeterA calorimeter is a device that measures the temperature changes of chemical reactions.
Dartmouth College provides information about how a calorimeter works. This website also provides alternative options to purchasing expensive calorimeters.
Gas centrifugeA gas centrifuge is a specialized piece of equipment used in the uranium enriching process. It separates U-238 and U-235 isotopes, which enables the user to alter the chemical makeup of the uranium.
Institute for Science and International Security and GlobalSecuirty.org offer detailed information about the gas centrifuge and its specific uses.
