Double Beam UV-VIS Spectrophotometer

Salient Features

    The two detectors are used to measure sample and reference respectively and simultaneously for optimizing measurement accuracy.
    Lamp selection enables conserving the life of D2 & Tungsten lamnps. Real time clock for date & time stamping of results.

    LIGHT PATH DESIGN: DOUBLE BEAM

    LMSP-UV1900 double light design can prevent circuit fluctuation and stray light to ensure stability of the instrument.

    LONG PATH LIGHT DESIGN

    LMSP-UV1900 unique 520mm long light path design greatly improved resolution and the bandwidth can reach 0.5nm.

    16MM OPTICAL BASE

    LMSP-UV1900 series use a rigid 16mm diecast aluminum base as their optical mount to ensure the stability and reliability.

    6 INCHES LCD DISPLAY

    LMSP-UV1900 series have a 6 inches LCD display to show results and curves directly on the screen.

    SOFTWARE FUNCTIONS ( (optional)

    Multi functions operated directly on the spectrophotometer and display the test results' curve and data: wavelength scanning, standard curve, kinetics, multi wavelength scanning, DNA/protein test.

    PERFECT CALIBRATION SYSTEM

    All baseline, wavelength, dark current can be calibrated automatically to keep good running conditions.

    DATA OUTPUT

    LMSP-UV1900 series are equipped with USB port to connect with a PC ( software optional ) comes standard with the instrument.
