HK-255 Petroleum Distillation Apparatus
Product Overview
The HK-255 Petroleum Distillation Apparatus is designed for determining the distillation characteristics of petroleum products in accordance with GB/T 255 and ASTM D86 testing standards. It is suitable for analyzing the fractional composition of gasoline, engine fuels, solvent oils, and other light petroleum products.
Featuring a quartz tube heating system, stainless steel bath, and stepless solid-state temperature control, the HK-255 provides stable heating performance and accurate temperature regulation throughout the distillation process. It is an economical and dependable solution for petroleum laboratories, refineries, fuel quality inspection agencies, and research institutions.

Features
●Fully compliant with ASTM D86 and GB/T 255 standards.
●Quartz tube heating provides fast and uniform heat transfer.
●Durable stainless steel heating bath resists corrosion and ensures long service life.
●Stainless steel lifting frame allows convenient positioning of the distillation flask.
●Silicone stopper securely fixes both the thermometer and distillation flask.
●Solid-state voltage regulator enables smooth stepless temperature adjustment.
●Heating temperature can be customized according to testing requirements.
●Compact laboratory design with simple operation and reliable performance.

Working Principle
The HK-255 determines the distillation range and boiling point distribution of petroleum products by heating a measured sample under standardized conditions.
During the test, the sample contained in a 125 ml distillation flask is heated gradually. As the sample evaporates, the vapor condenses and is collected while the corresponding temperatures are recorded throughout the distillation process. The resulting distillation curve provides valuable information for evaluating fuel volatility, composition, quality, and compliance with industry specifications.
