Double-Beam UV-Visible Spectrophotometer XU-8, 1.8 nm Bandwidth (CAT#: STEM-AL-9051-ZJF)

The XU-8 is a double-beam UV-visible spectrophotometer intended for high-stability ultraviolet-visible spectrophotometry. It is designed to perform transmittance, reflectance, absorbance, concentration, energy, kinetic, biomolecular, and multi-wavelength measurements. The optical, thermal, or analytical configuration uses a double-beam monochromator with a 1200 lines/mm holographic grating. Operation is supported by a 7 in touchscreen, USB storage, Bluetooth output, and CSV data handling. The instrument provides the measurement modes and data handling functions stated in the source. It can be integrated into UV-visible laboratory analysis requiring reduced photometric noise. The stated performance and operating limits are restricted to the source-provided specifications. Overall, the system provides a double-beam UV-visible platform with narrow fixed bandwidth.
