Twister
The Premex Twister is a flexible high-pressure batch reactor designed for laboratory and small-scale pilot applications. With reactor volumes from 60 ml to 1000 ml, it is suitable for a wide range of pressure reactions including hydrogenation, polymerisation and catalyst research. The Twister combines magnetic stirring, practical vessel handling and integrated pressure monitoring in a compact system for reliable and efficient high-pressure operation.
