Temperature Control - Convection Heating Systems (-150 ºC to +1000 ºC)
Perfect temperature control for measurements on melts and solids (DMTA) and extensional rheology on films and fibres - the convection heating systems for the Physica MCR series make it happen. Due to their symmetric design they guarantee gradient-free and accurate temperature control in all measuring systems, from parallel plates to solid bar fixtures, for optimal results when measuring polymer melts, glass melts, metal melts and solids. With their innovative design and comprehensive range of accessories, the convection heating systems are a must for experienced rheologists.
