Dry 1 K Top Loader
The Dry 1 K Top Loader is a closed cycle variable temperature cryostat in which the sample can be inserted from above. This innovative system allows for sample changes without warming up the cryostat or risking blocking the closed cycle system. The system can be easily fitted with a 1D / 2D / 3D superconducting magnet and optical access and allows for a broad range of different experiments, even down to 1.5 K.
