Optical Spectrophotometers

DOUBLE BEAM

GBC CINTRA UV/VIS/NIR dual-beam spectrophotometers

Cintra's new series of high-performance dual-beam spectrophotometers offers the versatility needed for the diverse needs of the modern laboratory.

The range covers all needs from routine quality control to very high performance systems with very low scattered light, analysis up to 4 absorbance units, variable bandwidth and dual monochromator. Optional extended measuring range (up to 1200 nm), all accessories for automating and speeding up analysis are available. Among the wide range of accessories are the integrating sphere (UV and VIS) for reading solids, films, pastes, creams, lenses, etc.; micro-sampling and Peltier thermostatting.

'CINTRA' SERIES double-beam UV/VIS Spectrophotometer

The CINTRA series spectrophotometers combine highly advanced optics, characterised by the perfect symmetry of the two beams and the highly sensitive front-window photomultiplier, with function-rich, graphically pleasing and versatile software.

The main technical specifications of the Cintra series spectrophotometers are:
