Spectrophotometer 4211/20 UV/Visible

The model 4211/20 spectrophotometer is an optical analysis equipment for the visible region of the electromagnetic spectrum that integrates digital wavelength control, internal data storage, and advanced analytical processing functions, positioning itself as a complete solution for laboratories that require greater operational capacity and precision.

It operates in a spectral range from 325 to 1000 nm with a bandwidth of 4–5 nm, allowing for the determination of absorbance, transmittance, and concentration with high reliability.

The single-beam optical system, based on a 1200 lines/mm diffraction grating and a silicon photodiode detector, provides stability and reproducibility in demanding analytical applications.

The digital wavelength adjustment via keyboard allows for precise and quick selection, optimizing working times and reducing operational errors.

The equipment incorporates a high-resolution LCD screen (128×64 pixels) that allows for visualizing not only measurement values, but also calibration curves and graphic representations, facilitating direct analysis without the need for external equipment.

It has internal memory with capacity to store up to 200 data sets and 200 calibration curves, significantly improving efficiency in repetitive analyses.

The sample compartment includes an external manual changer with capacity for 4 standard 10 mm cuvettes, allowing continuous work with multiple samples.

Connectivity via USB and parallel port allows integration with computer systems and printers. The included MWave Basic software expands the capabilities of the equipment, facilitating remote control, data processing, and generation of analytical results.

Thanks to its combination of precision, storage, and analysis capability, this model is especially suitable for quality control, research, and advanced teaching laboratories.
