Real Boiling Point Distillation Tester WM-1001A

Main technical parameters:

1. Determination of sample distillation range: determination of the actual boiling points of oil products such as naphtha at 35-180 ℃, heavy aromatic hydrocarbons at 80-350 ℃, and olefins at 35-80 ℃.

2. Distillation is carried out in two stages: the first stage is atmospheric distillation, where each fraction from the initial boiling point to 200 ℃ is cut; The second stage is vacuum distillation with a residual pressure of around 1.33 kPa, cutting various fractions from 200 ℃ to 395 ℃;

3. The theoretical number of plates in the distillation column is 15-17 layers, with a reflux ratio of 10:1, and full reflux can also be set

4. Operating actual boiling point cutting temperature: room temperature~350 ℃

5. The narrowest cutting temperature is 10 ℃

6. Operating pressure 1-760mm Hg
