New UV-Visible spectrophotometers

The Cintra 404 is a true double beam, double monochromator spectrometer which offers the ultimate in resolution and sensitivity. Using a variable slit width from 0.1 to 2.0nm, and dual Littrow monochromators in a Czerny Turner arrangement to achieve the highest resolution with extremely low stray light. Photometric linearity is now better than 1.2% at 5 Abs!. The wide dynamic range and excellent other optical specifications make the Cintra 404 the best performing UV instruments in it's price range allowing for the most demanding applications.

The Cintra 303 is a research grade spectrometer with enhanced sensitivity in the UV range. It has a variable slit width for best sensitivity and resolution, with improved stray light, noise, and drift specifications. The Cintra 303 accepts the full range of GBC accessories for it's wavelength range of 190 to 900nm making it the perfect instrument for specialised and research applications

The Cintra 202 will challenge many higher priced UV-Vis and UV-Vis-NIR instruments with its wavelength range of 190 to 1200nm and very low stray light and noise specifications. This true double beam spectrometer will suit routine lab work or more advanced applications reaching into the NIR regions. With a full range of accessories available including sample changers, auto samplers, peltier or water thermostattable temperature control, reflectance spheres capable of measurement up to 1150nm, this low cost instrument provides maximum flexibility and power for all applications.

The Cintra 101 is a budget priced entry level instrument. It is a true double beam spectrometer with low stray light and noise specifications. The Cintra 101 is now available with Windows® XP based Cintral software and is capable of wavelength scanning, time scanning, fixed wavelength measurement, Quantify application and an Instrument Validation application.

Spectral software, operating under Windows®, provides full instrument and accessory control, plus powerful graphics and data manipulation capabilities. It comes complete with a range of integrated applications for simple absorbance measurement, wavelength scanning, concentration, kinetics, multi-component, colour analysis, DNA melt analysis as well as GLP/GMP compliance. A fully customisable user interface allows the user to simplify routine analysis with one-click method access, standard calibrations, or formatted reports.

Powerful graphics and data manipulation
The real power of Spectral software becomes evident with the wide range of manipulations including zooming, annotation, derivative calculation, data smoothing, addition, subtraction, calculation of peak tables, determination of colour co-ordinates, determination of Tm and %GC, etc.

Quality protocols
Data integrity is assured with history functions to meet GLP requirements, including date and time stamping, plus instrument serial number, data manipulations log, method file storage and password protection.

SBasic Programming Language for Spectral UV-Visible software
Simplify routine analyses and complex data manipulation with SBasic macros. A newly published application note from GBC Scientific Equipment describes how the SBasic language is used with GBC's Spectral software to automate data acquisition and manipulation for UV-Visible analysis
