Centrifuging a Sample  John W. Moore, Jerrold J. Jacobsen, Lois M. Browne, John F. Zimmerman
The demonstration on this page shows a technique that should not be used by undergraduate chemistry laboratory. This video shows what happens to sample in a centrifuge while the centrifuge is on, and the result of stopping the centrifuge improperly. A narrative is included in this video: The centrifuging process allows the solvent to completely settle out. The jarring caused by hand braking destroys the distinct separation between supernatant and solid.

Thermometer (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Thermometer: this is a resource in the collection "ChemPages Laboratory Resources". A thermometer is used to measure the temperature of solids, liquids, or gases. A thermometer contains a liquid (usually mercury or an alcohol solution) in a reservoir whose volume is linearly dependent on the temperature (as the temperature increases, the volume increases). The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.

Balance (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Balance: this is a resource in the collection "ChemPages Laboratory Resources". A laboratory balance is used to measure the mass of reagents or laboratory equipment. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
