This instrument was purchased in 1994 from a biology department ILI grant for use in the molecular biology and biochemistry programs. The centrifuge is used to separate precipitated biological materials from solution. This instrument, which was purchased in 1993 with funds from the Carver Foundation, is used to separate and quantify a variety of inorganic molecules. This instrument also features a scanning UV detector which can obtain a 190-350 nm spectra of a given peak. This instrument utilizes measurement of the fundamental vibrational frequencies of molecules to both identify and quantify them.
Samples can be in gas, liquid, or solid phases.
These elements are often used as tracers in biological and biochemical applications. This instrument is used to measure the concentration of metals in a variety of matrices. Applications include the analysis of lead in paint and soils, metals in oil, iron in flour , and zinc in streams. It features a thermostated sample holder, automatic six sample changer, sipper sampling accessory, and a variety of data handling functions. This equipment enables students and faculty to carry out a range of electrochemical experiments including cyclic voltametry, stripping voltametry, differential pulse polarography and others.
