Spectrophotometer 4251/50 UV/Visible with Scanning

The UV/Visible Spectrophotometer 4251/50 is a high-precision instrument designed for advanced applications in molecular biology, biochemistry, and instrumental analysis, offering reliable measurements in the spectral range of 190 to 1100 nm.

Its single-beam optical system with a 1200 lines/mm diffraction grating and silicon photodiode detector provides excellent stability and sensitivity. The 2 nm bandwidth and a stray light level of ≤ 0.05 % ensure highly reproducible results even in demanding analyses.

The digital wavelength control allows adjustments with 0.1 nm resolution, ensuring precision in spectral selection and optimizing the quality of the data obtained.

The equipment allows working in absorbance, transmittance, and concentration modes, including quantification using calibration curves and kinetic analysis for the study of enzymatic reactions.

It integrates independent deuterium (UV) and tungsten (visible) lamps, optimizing performance across the entire spectrum and prolonging the system's lifespan.

The sample compartment accommodates up to 4 standard 10 mm cuvettes via manual exchanger, facilitating comparative analyses. It is supplied with 4 optical glass cuvettes and 2 quartz cuvettes, allowing work in both UV and visible ranges.

The interface includes a 128 × 64 pixel LCD screen with data, curve, and equation visualization. It has storage capacity for up to 200 results and 200 calibration curves, improving efficiency in repetitive analyses.

The equipment incorporates connectivity via USB and parallel port, and includes the MWave Basic software, which allows computer control, spectral scanning, multi-point analysis, and biomolecule identification.

Furthermore, it has an automatic data recovery function in case of power interruption, increasing operational safety.

This spectrophotometer constitutes a robust and high-performance solution for laboratories that require maximum precision, versatility, and advanced analytical capabilities.
