Descriptors: Biological Sciences, Equipment Manufacturers, Instrumentation, Science Equipment

Brooks, Austin E. – BioScience, 1978
Describes a device for maintaining the proper water level in knife boats during ultramicrotomy. Water levels in troughs are adjusted rapidly and precisely during the cutting process. Illustrations are included. (Author/MA)
Descriptors: Biology, College Science, Higher Education, Instrumentation

Stedman, Donald H.; Meyers, Philip A. – BioScience, 1974
Discusses advances made in chemical analysis instrumentation used in environmental monitoring. This first of two articles is concerned with analytical instrumentation in which detection and dispersion depend ultimately on the properties of gaseous molecules. (JR)
Descriptors: Air Pollution, Chemical Analysis, Chemistry, Chromatography

Coulter, Charles L. – BioScience, 1979
Presented are problems related to replacement and purchasing complex laboratory instruments necessary in biological research. Increased costs of equipment and leveling of research support are acknowledged as contributors to the problem. (SA)
