  • Model 721G UV-VIS Spectrophotometer
  • Specifications of Model 721G UV-VIS Spectrophotometer:

    1. Features:

    1). The monochromator with a holographic flashing grating is used. It has the advantage of high wavelength precision, good monochromaticity and low stray light.
    2). Automatic switching of halogen lamp and deuterium lamp.
    3). A sample compartment for 0.5cm~10cm cells.
    4). Computer control system, precise automatic T/A changeover.
    5). Automatic zero and full scale adjustment.
    6). Direct concentration read-out and concentration factor setting function.
    7). Equipped with RS232 port. Printer can be connected and data can be sent to PC by special software.
