Spectral testing high-pressure liquid sample chamber, designed for measuring fluorescence spectra (fluorescence lifetime) and absorption spectra under high-pressure environment, can be used for liquid and solid samples. The pressure can reach 4kbar (equivalent to 43500psi or 400MPa); The high-pressure chamber is equipped with three 10mm diameter quartz windows, distributed at a 90 ° angle, for fluorescence and transmittance absorption testing of L-type and T-type. Four windows can also be configured to simultaneously test fluorescence and absorption data. Sapphire windows can be chosen.

The composition of the high-pressure liquid chamber system for spectral testing includes: high-pressure liquid chamber, ultra-high pressure pump, sample cell, and constant temperature maintenance bottom plate. Most models of spectrometers can be configured, and special models can also use fiber optics to export and import beams. It can be placed on an optical platform and built into a comprehensive spectral measurement system for independent use.
