Fundamental Principle:
◆The fundamental principle of spectrophotometer is based on the fact that materials of different molecular structures have different absorptive selectivity towards electromagnetic radiation.
◆The UV spectrophotometer is commonly applied to 200-400nm spectral region of electromagnetic radiation detection and the corresponding instrument is called UV spectrophotometer.
Application
◆To analyze and study unsaturated & asymmetrical electron compounds and compounds possessing conjugate system especially
◆Organic compound & biological product analysis and RNA study
Feature
◆4 digit data display
◆Auto 0%T & 100%T adjustment, T.A.C. direct readout
◆Optional external printer connected to the instrument
◆Weighted only 7kg
