Cobalt
The Premex Cobalt is a versatile combi reactor system designed for laboratories that need both glass and steel reactor capability in one platform. The system allows users to switch between a borosilicate glass reactor for visual observation and lower-pressure processes, and a steel pressure vessel for higher-pressure operation. With hydraulic lifting, quick vessel exchange and a shared reactor head, Cobalt provides a flexible solution for research applications requiring practical handling, process visibility and pressure capability in a single system.
