UV/VIS Spectrophotometer

Model: LI-UV-2500

Features

Light path design: double beam

6 inches LCD display LCD display to show results and curves directly on the screen.

Powerful function

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

Perfect calibration system

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

Lead Screw Structure

The instrument has a lead screw structure to make the rotation angle of the grating perfectly, so that the instrument wavelength accuracy and wavelength resolution can be greatly improved.

8mm thick optical base

A rigid 8mm die-cast aluminum base as its optical mount to ensure instrument stability and reliability.

Data output

LI-UV-2500 is equipped with USB port to connect with a PC to display spectrum scanning, kinetics and multi wavelength testing results on the screen.
