Double Beam UV/Vis Spectrophotometer 4260/50

The UV/Visible spectrophotometer model 4260/50 is a high-end equipment designed for advanced spectrophotometric analysis, incorporating dual-beam technology that allows simultaneous measurement of the sample and the reference blank, guaranteeing maximum stability and accuracy in the results.

Its optical system, based on a 1200 lines/mm diffraction grating and a double detector, provides high precision throughout the spectral range of 190 to 1100 nm. The configurable bandwidth (0.5 / 1 / 2 / 4 / 5 nm) allows the balance between resolution and sensitivity to be adjusted according to the analysis requirements.

The equipment supports multiple working modes, including absorbance measurement, transmittance, concentration, kinetic analysis, spectral scanning, and multi-frequency determination, facilitating the study of complex samples and dynamic processes.

It integrates independent deuterium (UV) and tungsten (visible) lamps, optimizing spectral performance and allowing efficient control of their useful life.

The UV/Vis Analyst software, compatible with the Windows environment, provides advanced equipment management, allowing unlimited data storage, report generation, spectral analysis, and subsequent results processing. The system can operate autonomously or connected to a computer.

The quantification functions allow working with up to 10 standards, using linear, forced-to-origin linear, and second- and third-degree polynomial regression models, adapting to different analytical methods.

The spectral scanning mode allows selecting increments from 0.1 nm and adjustable speeds, incorporating analysis tools such as automatic peak detection and curve rescaling.

Kinetic analysis allows recording absorbance variations at programmable intervals from 0.5 seconds to 1 minute, during prolonged periods, facilitating the study of enzymatic reactions and dynamic processes.

The equipment includes specific functions for the determination of nucleic acids and proteins using absorbance ratios (260/280 nm and 260/230 nm), allowing the evaluation of concentration and purity of biological samples.

This spectrophotometer constitutes a high-performance solution for laboratories that require maximum precision, stability, and analytical capacity in research, quality control, and advanced instrumental analysis.
