Spectrophotometer SP-1900 (Double Beam UV-Vis Spec

It takes a technology Compared with traditional double beam technology, simplified optical path improved reliability. The Original Touch Screen of SP-1920, the end users could control the instrument by the touch screen without the keypress. Streamline apperance and pretty colors express a new style fashion.
