SP-1901 dual-beam UV-Vis Spectrophotometer Instrument Description
SP-1900 series dual-beam UV-Vis spectrophotometer using original design of the vertical distribution of pairs of optical detection, dual-detector system (patent pending), to subvert the traditional optical design concept, the unique design of the instrument detection optical path than the traditional reduced by nearly two-beam apparatus greatly reduces the energy loss caused by multiple reflections, the instrument signal to noise ratio increased significantly. Not only that, because of the unique optical distribution system, but also the size of the instrument is only one-half of traditional products! Effectively saves lab space.
SP-1901 dual-beam UV-Vis spectrophotometer with 1nm spectral bandwidth designed to meet the Chinese Pharmacopoeia and European Pharmacopoeia requirements, is the drug test, drug research, pharmaceutical inspection and necessary equipment, but also medicine, pharmacy class universities research and teaching of the best products.
SP-1901 series dual-beam UV-Vis spectrophotometer in tertiary institutions, research institutes, doping sector, the pharmaceutical industry to purchase and upgrading the best choice!
SP-1901 dual-beam UV-Vis Spectrophotometer Features
