    Tips: Maintaniance for Spectrophotometers

    Spectrophotometers are precision instruments. Due to the working environment, operating methods and so on, its technical conditions will inevitably change in the operation, which may affect the performance of the instrument, and even cause the equipment failure. Therefore, analysts are able to detect and eliminate these hidden dangers in time, in order to ensure the normal operation of instruments and equipment.

    • If the test wavelength is changed significantly, wait for a moment until the lamp reaches heat balance, recalibrate the "0" and "100%" points and then measure again.
    • After using the cuvette, immediately rinse it with distilled water and wipe the water mark with clean soft gauze in case of the damage of surface which will affect the light transmittance of the cuvette.
    • The operator had better not move the light bulb and reflector lamp, so as not to affect the light efficiency.
    • After the amplifier sensitivity shifts, it must be re-zeroed.
    • Cuvettes should be assorted. The cuvette must be compatible used; otherwise it will make the test result meaningless.
    Existing reviews of Visible Spectrophotometer, Single Beam, 340/325-1000nm
    Visible spectrophotometer provides 4 cuvettes
    We need a multi-cell holder: at least 2 cuvettes should be connected to the visible spectrophotometer?
