Based on customer requirements, GoGo Instruments delivered a customized electrical heating and cooling stage to a university in Russia. The product utilizes liquid nitrogen for cooling and resistance heating, providing precise temperature control within the range of -190°C to 400°C. Its high-vacuum chamber design is compatible with low-magnetic-field environments, enabling relevant material testing and research.

The equipment is constructed using non-magnetic or low-magnetic materials to be compatible with the customer's magnetic field generation equipment. Furthermore, since the customer's equipment base lacked threaded holes for mounting, the support frame was designed to fix the stage by pressing its legs against both side walls and then using screws to press downward against the base plate. This design allows seamless compatibility with the customer's existing equipment without requiring any modifications, fully meeting the customer's testing needs.
