UV/VIS Spectrophotometer

Model: LI-UV-7000


Light path design: double beam

This series’ double light path design can prevent circuit fluctuation and stray light to ensure stability of the instrument.

Long path light design

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

16mm optical base

This series use a rigid 16mm diecastaluminum base as their optical mount to ensure the stability and reliability.

6 inches LCD display

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

Powerful software functions

Multi functions like spectrum scanning, standard curve, kinetics, multi wavelength scanning, DNA/Protein testing can be operated directly on the spectrophotometer and all corresponding curves and data can be displayed directly on the PC.

Multi functions on spectrophotometer

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

LI-UV-7000 series are equipped with USB port to connect with a PC, the software comes standard with the instrument.
