UV-Visible Spectrophotometer LH-S700, 190-1100 nm (CAT#: STEM-AL2-1297-ZJF)

The UV-Visible Spectrophotometer LH-S700 is designed for UV-visible spectrophotometric analysis. It provides optical measurement across the stated wavelength functions for laboratory absorbance and quantitative analysis. Its configuration is based on the operating modes, sample interfaces, and control functions explicitly provided in the source text. The system is intended to reduce manual handling while maintaining a repeatable analytical or sample-preparation sequence. Where digital control or data functions are provided, they support routine operation, result handling, and method consistency. Compatible sample formats and accessories are limited to those identified for the product in the source. The product is suitable for laboratory or field use only where that use is supported by the stated configuration. Its core role is UV-visible spectrophotometric analysis within a controlled technical workflow.
