HK-7345K Rapid Micro Distillation Tester
Product Overview
The HK-7345K Rapid Micro Distillation Tester is a fully automatic petroleum distillation analyzer designed in accordance with NB/SH/T 6071 Determination of Atmospheric Distillation Characteristics of Petroleum Products—Micro Distillation Method and ASTM D7345.
The instrument is suitable for determining the distillation characteristics of gasoline, diesel fuel, aviation gasoline, and jet fuels using only 10 mL of sample. A complete distillation test is finished in 15 minutes, providing results equivalent to those obtained by GB/T 6536 and ASTM D86 while significantly reducing sample consumption and testing time.
Featuring a 7-inch color touchscreen, intelligent automatic operation, built-in pressure and temperature compensation, comprehensive safety protection, and LIMS connectivity, the HK-7345K is an ideal solution for modern petroleum laboratories requiring high efficiency and reliable analytical performance.

Working Principle
The HK-7345K uses the micro distillation method to accurately determine the distillation characteristics of petroleum products.
A 10 mL sample is heated under precisely controlled conditions. During distillation, built-in sensors continuously monitor temperature, pressure, and evaporation progress. The instrument automatically calculates the evaporated volume percentage and corresponding distillation temperatures while applying real-time temperature and barometric pressure corrections. The final distillation curve closely matches results obtained using conventional ASTM D86 atmospheric distillation testing.
