EuroDist Potstill-S
Advanced Distillation system according to ASTM D5236
The ROFA EuroDist Potstill-S impresses with its extended capacity and a completely modular construction. Thanks to the many practical functions and individual product features, this system becomes the perfect solution for every laboratory. The ROFA EuroDist Potstill-S reliably handles distillation jobs with flask sizes up to 30 litres and keeps 20 receivers with a size of 500 or 1000 ml ready for your distillation output.

The distillation column has 15 -18 theoretical plates and complies fully with the ASTM D2892.
In normal operation mode, the plant completes a preheating and evacuation to the first vacuum stage (1 Torr), distilling until a predetermined flask temperature and reduces pressure to 0,2 Torr while continuing distillation.
After the final cut, it carries out a final cooling sequence.There is a special mode which allows (performing / completing – which you prefer) a full distillation including an initial debutanization.
This is especially interesting for customers who have the knowledge in data conversion from Potstill yields to TBP yields, as it can save up to 80% of the distillation time.
ASTM D5236
The ASTM D 5236 (Potstill) can fractionize crude oil or crude oil residue from 150°C up to 570 °C (at atmospheric equivalent temperature); from atmospheric or 10 Torr pressure down to a vacuum of 0.1 Torr.
