Dual Beam UV-VIS 2000 Spectrophotometer

The UV 2000 is a high performance compact Dual Beam Spectrophotometer with a fixed 2nm spectral bandwidth.

The UV 2000 range consists of two models:

  • UV 2000U (UV-Visible) operating within a wavelength range of 190 -1100nm.
  • UV 2000V (Visible) operating within a wavelength range of 320 -1100nm.
  • The instrument has a switched mode power supply accepting voltages in the range of 95  240V AC and supplied with 10mm path length 4 cell changer as standard.
  • The UV 2000 delivers the functionality and accuracy of an advanced instrument at an affordable price.

FEATURES & FUNCTIONS

• High performance fixed 2nm spectral bandwidth.

• Low stray light 0.05%T.

• Wavelength accuracy +/- 0.5nm.

• Holographic blazed grating 1200 lines/mm.

• Software (M.Wave Professional) control for photometric fixed wavelength measurement.

• Easily upgraded to include quantitative analysis, multi wavelength spectrum & kinetics.

• Robust modular design with a small footprint.

 

OPTICAL SYSTEM & COMPONENTS

High quality optical components ensure reliable analytical data with low stray light achieved using very low noise electronic circuits.

Deuterium and tungsten light sources deliver superior stability across the full wavelength range. Both types of lamp have self timers and are inexpensive and easy to replace when required.

The monochromator is completely sealed and the optical surfaces can be easily cleaned to maintain optimum reflectivity over the lifetime of the instrument.

A maintenance free high resolution direct stepper drive positions the grating precisely, which ensures reproducible wavelength scanning at different scan speeds,

thus negating any wavelength peak shift.

The spectrophotometer shell is made from an environmentally friendly non corrosive material and a simple retaining mechanism on the base allows easy access for air filter changes and routine maintenance.
