Easy to Operate

  • The intuitively designed LCD and buttons enable users to quickly and easily take measurements, execute instrument validation and printing operation
  • The checks for JIS items can be performed automatically or semi-automatically.
  • Linking with a 6-series multi-cell (optional) is possible, making sample replacement unnecessary. Inspections can be performed efficiently.

Broad range of High-Level Measurement Modes

Equipped with a range of programs, the UV-1280 can be used for everything from photometric, spectral, and kinetics measurements to DNA/protein and high-level multi-component quantitation.

Data Storage on USB Flash Drives

  • Easy to transport analysis data and for storing large amounts of data in a PC.
  • Directly connectable to the UV-1280.
  • Data for spectra and time-course curves can be displayed and saved with commercial spreadsheet software.
