Spectrophotometer Single or Double Beam

Spectrophotometer is an optical instrument for measuring the intensity of light relative to wavelength i.e. Luminous intensity (Iv) is inversely proportional to wavelength (lemda). It uses the concept of Spectrophotometry which is a method to measure how much a chemical substance absorbs light by measuring the intensity of light, as a beam of light passes through sample solution. The basic principle is that each compound absorbs or transmits light over a certain range of wavelength.In this way the qualitive and quantitive analysis of chemical substance in solution is found.(Luminous intensity typically is represented by the symbol Iν, where the subscript ν denotes a photometric quantity, and its unit is the candela, an SI base unit (1 cd = 1 lumen/steradian, where the steradian is a measure of solid angle). An antique term for the candela is candlepower.)

Product Information->

Centrifuge

Centifuge

A centrifuge is a laboratory device that is used for the separation of fluids, gas or liquid, based on density. Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force (out pulling force) pushes heavier materials to the outside of the vessel.
