The LMSPV325 Visible Spectrophotometer is designed for routine analytical applications in the visible wavelength range from 325 to 1000 nm. It uses a single beam optical system with a 1200 lines/mm grating to provide stable and consistent photometric measurements.
The instrument features automatic wavelength setting, allowing users to quickly select required wavelengths with minimal operational error. It supports standard curve generation, enabling quantitative analysis and determination of unknown sample concentrations.
The system provides multiple result display capability, showing wavelength, absorbance, and transmittance simultaneously, with memory storage for up to 200 results. A compact LCD interface ensures clear data visualization and ease of operation.
Equipped with a tungsten lamp and silicon photodiode detector, the instrument delivers reliable performance across the visible spectrum. A 4-position cuvette holder allows efficient sample handling, while USB connectivity enables data transfer to external systems and printer integration.
The LMSPV325 is suitable for laboratories requiring a cost-effective solution for routine visible range analysis without the need for UV capability.
