ERRECI
Double beam

The main technical characteristics of the Cintra series spectrophotometers are:

• Variable bandwidth from 0.5 to 8 nm;
• Ultra-micro sampling available: 50 µl (5 µl with special ultra-micro cuvette);
• Selectable scan speed from 1 to 4000 nm/min in 1 nm/min increments;
• Onboard GLP-compliant software for scans in %T, ABS, derivatives and spectral reprocessing; all reprocessing is displayed on screen and in print (no PC required);
• Onboard software for quantitative analysis:
• Quantitative analysis in A, %T and concentration, with on-screen display of linear, quadratic or cubic curves, calculated using up to 30 standards;
• Display and printout of calibration curve statistics;
• Reprocessing of uncorrected standards; recall, display and print curves and methods;
• Secure storage of 100 methods, including calibration curves;
• Ratio, absorbance difference and spectra; area measurement with baseline correction; multi-wavelength analysis;
• Calculation of derivatives from 1st to 6th order;
• Overlay of derivative spectra;
• Secure storage of 100 spectra;
• Combined programming of up to 10 wavelengths for each measurement cell;
• Second sample compartment for turbid samples;
• Fully sealed and covered optics to maintain specifications over time;
• Computer-independent instrument (optional serial link, ready for use with or without control software).

They feature a virtual double-beam optic: the optical-electronic system consists of a beam produced by a Xenon lamp, and an electronic beam, called "virtual," with a "correction" function for the instrument's best performance. This correction function is guaranteed by the acquisition of a baseline, regularly compared with current readings, thus allowing the instrument to perform scans equivalent to those of a double optical beam.

The advanced microprocessor and sophisticated resident software allow for a high analytical standard, thanks to the constant monitoring and processing of the results that the instrument provides.

Thanks to its small number of mirrors and completely sealed optics, the instrument guarantees high system energy, long-term reliability, and extremely low maintenance costs. It offers the same performance as dual-beam optical systems. All models are ISO9002 certified and bear the CE mark, having been manufactured in compliance with EEC LVD and CEM 89/336 standards.

The main technical features of the series are:

Automatic wavelength calibration with self-diagnostics of optical, mechanical and electronic functions during startup;

Automatic search for the peak of maximum absorbance with baseline correction;

Concentration readings with automatic calculation and/or manual entry of the K factor;

Fully sealed and coated optics for safe maintenance of specifications over time

High-resolution LCD graphics monitor, 430 mm total width, with “display scrolling” function

Possible Ultra-micro sampling 50 µl (5 µl with special ultra-micro-cuvette);

Stray light < 0.01% at 220 and 340 nm;

Ratio of absorbances at two wavelengths for DNA/RNA (e.g. 260/280 nm) and OLI (e.g. 220/240 nm) measurements;

Fully sealed and coated optics to maintain specifications over time;

Quantitative analysis in A, %T and concentration, with 1st-, 2nd- or 3rd-order calibration curves using up to 30 standards, with storage for 30 methods and their calibration curves;

Computer-independent instrument (optional serial link, ready to use with or without management software).
