1. UV-Visible Spectrophotometer
Make : Shimadzu UV-1800
Application : UV/Vis spectroscopy is widely used in analytical chemistry for the quantitative determination of different analytes, such as transition metal ions, highly conjugated organic compounds, and biological macromolecules and in medical lab for quantitative estimation of blood sugar, cholesterol etc.
Standard Features: It is an advanced high-resolution compact double beam spectrophotometer which uses the Czerny-Turner mounting for its monochromator. It can be used either as stand alone item or as a PC controlled instrument that has wavelength resolutions with a compact bright optical system. USB memory can be connected directly to this instrument for simple data transfer.
-Source lamp-Deuterium, Tungsten-Halogen -Wavelength range: 190 – 1100 nm -Wavelength accuracy: ±0.1 nm -Dimensions (W x H x D): 450 x 270 x 490 mm.
Photometric Mode measures the absorbance or transmittance at a single wavelength or at multiple (up to eight) wavelengths. Spectrum Mode obtains sample spectra using wavelength scanning. Changes in the sample can be tracked using repeated scans. Kinetics Mode measures the change in absorbance as a function of time, and calculates enzymatic activity values.
Unique Features and Advantages : The recorded absorption spectra of unknown compounds can be correlated with the types of bonds in a given molecule and thus to determine the functional groups in a molecule. Also useful in calculating the concentration of unknown samples.
