Thermo UV1000 Single
Wavelength UV Detector
• Unique optical design reduces noise
• Programmable wavelength changes
• Flexibility with interchangeable flow cells
• Comes with analytical flow cell and
deuterium lamp
The unique dual-beam, forward optical design
of the Thermo UV Detector reduces noise and
drift by focusing the light beam away from the flow call walls.
Reference and sample beams are monitored at the same
length for a wide, linear dynamic range.

Thermo UV2000 Dual Wavelength UV Detector
• Collects up to 20 spectra per run in stand alone mode
• Dual wavelength operation for measuring absorbance
ratios
• Automatic lamp shut-down extends lamp life
• Comes with analytical flow cell and tungsten and
deuterium lamps
Thermo’s UV2000 provides an excellent signal-to-noise
ratio for research or routine analysis. Program different
wavelengths to improve sensitivity or selectivity of different
compounds.
