UV visible spectrophotometeradvantage

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 adoptsGerman Osram tungsten lamp, sent by the United StatesZhi detectorThe dual beam optical system and thickened optical substrate can better 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.

Performance characteristics:

The newly designed dual beam optical system provides excellent optical performance; The high-performance holographic glitter grating ensures low stray light in the instrument

·Design advanced circuit measurement and control systems Make the instrument highly stable and have extremely low noise

·Detachable structure sample chamber design, easy to replace different accessories To meet different analytical needs

·The spacious open light source room design makes it easier to replace the light source

·All key components are made of imported components Ensuring high reliability of instrument performance

·Chinese and English operating software developed in the Windows environment Provides rich and unique analysis functions
