Double Beam UV/Vis Spectrophotometer LUS-B11

Double Beam UV/Vis Spectrophotometer LUS-B11


Double beam UV/Vis spectrophotometer assures long term stability and durability. This double beam spectrophotometer with two detectors measures the sample and the reference simultaneously, also optimizes the measurement accuracy. Supplied with PC software, it has tungsten/halogen lamps which are very efficient, and their output extends well into the ultra-violet. The double beam spectrophotometer with 2 single cell holder are designed using complied using ISO/CE international standards.
