Double Beam UV-VIS Spectrophotometer (Model No. HV-SPUV Series)

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

LIGHT PATH DESIGN: DOUBLE BEAM

• HV-SPUV-1900 double light design can prevent circuit fluctuation and stray light to ensure stability of the instrument.

LONG PATH LIGHT DESIGN

• HV-SPUV-1900 unique 520mm long light path design greatly improved resolution and the bandwidth can reach 0.5nm.

16MM OPTICAL BASE

• HV-SPUV-1900 series use a rigid 16mm diecast aluminum base as their optical mount to ensure the stability and reliability.

6 INCHES LCD DISPLAY

• HV-SPUV-1900 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

• HV-SPUV-1900 series are equipped with USB port to connect with a PC
