Visible Range Spectrophotometer, 4201/20

The 4201/20 model spectrophotometer is equipment designed for analysis in the visible region of the electromagnetic spectrum, incorporating digital wavelength control and advanced functionalities for reliable quantitative measurements in the laboratory.

It operates in a spectral range of 325 to 1000 nm with a bandwidth of 4–5 nm, allowing for the determination of absorbance, transmittance, and concentration using methods based on coefficients or calibration curves.

The single-beam optical system, equipped with a 1200 lines/mm diffraction grating and a silicon photodiode detector, provides stability, sensitivity, and repeatability in standard analytical applications.

Digital wavelength adjustment significantly improves accuracy and ease of use compared to manual models, allowing for quick and accurate selection of the measurement point.

The equipment incorporates a sample compartment with capacity for up to 4 cuvettes of 10 mm using an external exchanger, facilitating work with multiple samples in an agile manner. Likewise, it supports cuvettes with different optical paths using optional adapters.

It includes USB connectivity and a parallel port, allowing integration with computer systems and printers. The MWave Basic software expands the capabilities of the equipment, facilitating data management, result storage, and calibration curve construction.

Thanks to its robust design, precision, and operational ease, this model constitutes a versatile solution for teaching laboratories, quality control, and research in chemistry, biology, and environmental analysis.
