Vivor / Varioso
The Premex Vivor and Varioso series are compact, small-volume high-pressure reactors designed for flexible laboratory use. Both models are available in 60 ml and 100 ml formats and can be configured with different materials to suit the required pressure, temperature and chemical compatibility. The Vivor is a compact standalone autoclave for small-scale pressure reactions, while the Varioso combines the Vivor reactor with a matched magnetic heating/stirring plate and coordinated cooling system for a more complete benchtop setup.
