Summary
The instrument is designed and made as per the National Standard of People's Republic of China GB/T7534-2004 "Test Methods for Boiling Range of Volatile Organic Liquids for Industrial Use". It is suitable to determine boiling range of volatile organic liquids for industrial use and organic solvents for material. If you prepare proper flasks, it can also be used to determine distillation characteristics of gasoline, aviation gasoline, jet fuels, solvents having special boiling point, naphtha, diesel oils, distillate fuels, and similar petroleum products.
