C. It solves the shortcomings of the previous use of artificial dry ice cooling, temperature caused by Dewar insulation is not easy to control, can only do one sample at a time, and difficult to analyze and test.

The petroleum asphalt wax measuring instrument can perform analysis test of three samples at a time. It has the advantages of rapid cooling, high control precision, easy operation, time saving and so on. It is an ideal analytical instrument for petroleum, chemical, construction, highway construction and other industries.

Purpose and scope of application

The method is suitable for determining the wax content of road petroleum asphalt by pyrolysis distillation.
