A pressure vessel and furnace for measuring absorption spectra of liquid systems at elevated temperatures and pressures is described. At 600°C, the assembly will operate at 300 atm. This apparatus was designed for use with either the Cary model 11 or the Cary model 14H spectrophotometer. The liquid sample is held in a standard 1-cm square absorption cell with a wide neck attached.
