  • Possibility of flowing cell use for process exception of research disposable polystyrene cells and saving budget funds
  • The big and convenient touch display with control without buttons
  • Full scanning of sample in the autonomous mode (190-1100 nm)
  • Great opportunities at connection to the personal computer and use specialized software

Replaceable cell holders and annexes

The large cell section of the spectrophotometer allows to change easily and quickly cell holders and annexes for carrying out various measurements

Measurement accuracy

Double monochromatic device provides the minimum level of the disturbing radiation that guarantees high precision of measurements


The pulse xenon lamp is used as the only light source in the PVN-spectrophotometer. The service life is almost unlimited, unlike halogen and deuterium lamps. Besides convenience in operation, it significantly decreases service expenses

Operation is more simply and quicker

The stray light doesn't influence the accuracy of measurements thanks to use of pulse xenon lamp. Working with the studied samples can be carried out at open cell section. There is no need to spend time for closing and opening cover during operating time

Touch screen

To work in the autonomous mode (without connection the spectrophotometer to the computer) conveniently thanks to existence of the big display with the touch control panel

Built-in printer

Printing of measurement results without connection the spectrophotometer to the computer thanks to the built-in thermal printer

Program support

Specialists of research department and development constantly improve the "UV-VIS Spectrum" program for operation spectrophotometers with computer. "SOLAR" provides to users free updates of the program during all term of device operation.
