UV-Vis. Double Beam Spectrophotometer-LMSPUV1928

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 lamps. Real time clock for date & time stamping of results.

LIGHT PATH DESIGN: DOUBLE BEAM

LMSPUV1900 double light design can prevent circuit fluctuation and stray light to ensure stability of the instrument.

LONG PATH LIGHT DESIGN

LMSPUV1900 unique 520mm long light path design greatly improved resolution and the bandwidth can reach 0.5nm.

16MM OPTICAL BASE

LMSPUV1900 series use a rigid 16mm diecast aluminum base as their optical mount to ensure the stability and reliability.

6 INCHES LCD DISPLAY

LMSPUV1900 series have a 6 inches LCD display to show results and curves directly on the screen.

SOFTWARE FUNCTIONS

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

LMSPUV1900 series are equipped with USB port to connect with a PC
