The 1.5K cryostat is capable of operating non-stop from 1.5K to 300K (450K optional) and is a cryogen-free, turnkey substitute to liquid helium. The device is a top-loading refrigerator is capable of ...

The PanScan Freedom eliminates the costs of liquid helium, complications of dewar switch-out and transfer hoses, hazards of interrupted experiments due to cryogen supply and safety issues related to ...

making it the most versatile cryogen free or Cryofree ® top loading cryostat, optimized for various spectroscopy experiments. The OptistatDry Cryofree series of cryostats for spectroscopy helps to ...

The 300 MHz, 400 MHz, and 600 MHz NMR magnets are always at field and never turned off. They are kept in the superconducting state by liquid helium that is insulated by vacuum and liquid nitrogen.

On the other hand, it is obvious that a model which is so far away from reality that it simplifies liquid helium to an ideal gas, cannot, for high temperatures, yield but7 the value Cv=3/2 R9 and ...
