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.
