Visible Range Spectrophotometer, 4101

The model 4101 spectrophotometer is an optical instrument designed for analysis in the visible region of the electromagnetic spectrum, offering a simple, robust, and efficient solution for routine applications in laboratory, teaching, and basic quality control.

Its manual wavelength selection system allows the working range to be directly adjusted between 330 and 1000 nm, facilitating operation even for users without advanced experience. Result reading is performed via a digital screen, providing clear values for absorbance and transmittance.

The equipment incorporates a single-beam optical system with a 1200 lines/mm diffraction grating and a silicon photodiode detector, ensuring stability and reliability in standard measurements within the visible range.

Reference adjustments are made quickly and intuitively through white calibration (0% absorbance) and auto-zero adjustment (0% transmittance), simplifying equipment preparation before each analysis.

The sample compartment is designed to accommodate standard 10 mm path length cuvettes, and includes two glass cuvettes and one dark reference cuvette for calibration.

Thanks to its compact and resistant structure, this spectrophotometer is easily integrated into any work environment, constituting a reliable tool for basic measurements in chemistry, education, and routine analysis.
