        Acryo 4K cryocooler

        Acryo 4K refrigerator uses a two-stage GM or pulse tube refrigerator as the cooling source. The sample environment for a standard Acryo 4K is vacuum. Acryo 4K has the characteristics of large temperature operation range, simple operation, and wide application range. Options include helium sample environment with indium sealed chamber, customized sample space, ultra-high vacuum compatibility, low vibration, optical windows, and feedthroughs, etc.
