| phase-contrast microscope | a special type of compound microscope that allows the details within living specimens to be seen without staining. |
| stereomicroscope | Type of light microscope used in studying the external structure of aspecimen. |
| transmission electron microscope | can magnify images more than 2500,000 times. Uses electron beams, rather than light, and electromagnetic lenses, rather than glass lenses. |
| scanning electron microscope | Uses an electric beam that has been focused to a fine point, the beam is passed back and forth over the surface of the specimen, causing elecrons to reflect from the specimen's surface and are collected to produce an image of great depth. |
| centrifugation | Materials of different densities suspended in a liquid can be seperated from each other by _____. The material that is to be seperated by being spun around, the heaviest particles settle to the bottom the fastest. they end up layering. |
| microdissection | tiny instruments are used to preform various operations on living cells, done under a microscope. |
| chromatography | Any technique that seperates different substances from each other on the basis of their chemical or physical properties. |
| electrophoresis | technique for seperating substances made up of particles that have an electrical charge. |
| spectrophotometry | method of using light to analyze samples of a substance to determin what a substance is and how much is present. |
