Abstract
A device for recording the boiling curve of liquids, in particular petroleum products, made of a distillation apparatus which includes a distillation column and a condenser, a sample dish connected to the distillation apparatus and a pump connected to the sample dish to fill the sample dish, wherein the filling means and the condenser are made of well heat-conducting material and the filling means and the condenser are connected to a temperature controller.
Claims19
A device for recording the boiling curve of liquids which comprises:
- a distillation apparatus comprising a distillation column (10) and a condenser (15);
- a sample dish (7) connected to the distillation apparatus;
- a filling means (1) connected to the sample dish (7) to fill the sample dish (7);
- and
- a temperature controller connected to the filling means (1) and the condenser (15),
- wherein the filling means (1) and the condenser (15) comprise material that conducts heat well,
- wherein the condenser (15) comprises an axial zone with reduced diameter of a material transparent to light, which is followed by a zone having a larger inner diameter, an axially movable piston (22) being received in said zone having a larger inner diameter.
