UV/Vis and Visible Laboratory Spectrophotometers
Benchtop instruments for absorbance, transmittance and concentration measurement across the ultraviolet and visible range, from routine visible-range photometry to double-beam and variable-bandwidth research systems. Select by measurement task below, then compare individual models in the catalogue.
Select by measurement task
Routine visible-range photometry
Compact visible-light instruments for colorimetric assays, water and food analysis and teaching laboratories. Typical range 320-1100 nm with 4-6 nm spectral bandwidth.
Single-beam UV/Vis scanning
General-purpose 190-1100 nm instruments for absorbance, concentration and wavelength scanning, with deuterium and tungsten sources and direct data export.
Double-beam UV/Vis
Reference-corrected optics for improved baseline stability and long measurement sequences: kinetics, spectral scanning and pharmacopoeia-style methods.
Variable spectral bandwidth
Selectable 0.5 / 1 / 2 / 4 / 5 nm bandwidth for methods that specify resolution, and for resolving narrow absorption features.
Xenon-lamp systems
Pulsed xenon source instruments with no warm-up requirement and extended lamp life, for laboratories with intermittent or high-throughput use.
Accessories and sampling
Quartz and glass cuvettes from 5 to 100 mm, automatic multi-cell holders, sippers and flow cells, Peltier temperature control and PC software options.
Choosing a model: the decisive parameters are wavelength range, spectral bandwidth, single- or double-beam optics, sampling method and data output. Send your application and required specification and COLO.Science will confirm the model and the approved configuration. Technical specification documents for each series are linked from the individual product pages. B2B prices are quoted net, excluding VAT.
