UV-VIS Shimadzu UV-2700 @User Chemistry Lab
UV-VIS
The Shimadzu UV-2700 is a mid-range UV spectrometer in use by the Users Chemistry Laboratory. It contains a double monochromator system capable of 8-Abs measurements. It is optimal for measuring samples with low transmittance.
During measurements, real-time data can be sent to Excel for using macros to automatically obtain desired values. There is also a feature, which allows Spectral evaluation and allows a pass/fail judgment for quality control.
The Shimadzu UV-2700 is suited for uses in the fields of electricity, electronics, optics, chemistry, textiles, civil engineering, life sciences and food products.
Selected Applications:- Determining the band gap of semiconductors
- Thickness Measurements of Cling Films
- DNA and Protein Measurements
- Vitamin Measurements
- Total transmittance Spektrum of CNF
