Purpose :
It is suitable to determine the distillation range of paraffin oils, lubricating oils, and other high boiling poin.
t
The instrument is designed and made as per the Industry Standard of People's Republic of China SH/T 0165-92 "Test Methods for Distillation range of High Boiling Point Petroleum Products at Reduced Pressure". It is suitable to determine the distillation characteristics of paraffin oils, lubricating oils, and other high boiling point petroleum products.
I. Main technical characteristics
1. The instrument is a desktop type. It s composed of distillation parts and vacuum parts. It is in accord with the requirements of SH/T0165.
2. The heating power of the distillation heating furnace can be continuously adjusted. It also has a cooling device for the heating furnace, so the heating furnace can be cooled down after a test. It is convenient to make next sample determination.
3. The performance of vacuum pump is excellent. The maximum residue pressure is 2mmHg.
