Product details
UV Visible spectrophotometer UV1902
UV visible spectrophotometerUsing Hamamatsu ozone free and environmentally friendly deuterium lamps, ordinary long-life deuterium lamps can produce ozone, which is harmful to the body if inhaled for a long time. Ozone free long-life deuterium lamps can effectively prevent this. The instrument also adopts German Osram tungsten lamp, American Laizhi detector, dual beam optical system, and thickened optical substrate to ensure the stability of the instrument. The operation interface and operating system are both simple and fast versions, reducing detection time while increasing accuracy The absorbance can be accurate to four decimal places. Multiple accessories can be selected, including automatic quadruple cell, seven cell, constant temperature device, transmittance solid frame, reflectance solid frame, etc.
