UV/Vis spectrophotometers, U-2900 and U-2910

Supplier: Hitachi
Reliable, accurate spectrophotometers for use in applications including biotechnology, material development and quality control.

  • High resolution satisfying European Pharmacopoeia
  • Stable optics and stigmatic concave diffraction grating for aberration-free measurements
  • Full range scanning over 190 - 1100 nm with a selectable scanning rate range of 10 - 3600 nm/minute

The U-2900 is designed for direct input of data and reading of results by the operator. It can be controlled externally by a PC with the (optional) UV solutions program.

The U-2910 is designed for PC control only.
