3.5 Pressure Vessel and Sample Storage Area
The dewar is based on the Chart’s MVE High Efficiency Freezers, with modifications to
incorporate a cryogen tank and cryocooler. The “lazy Susan” Carousel for sample racks
is suspended from the neck of the cryogen tank and can be turned easily using the
handles provided. The inner cryogen tank is filled nearly to the top, so that the entire
outside of the tank serves as heat-exchange surface to cool the air inside the storage
space. The initial fill of the cryogen tank is performed when the unit is first delivered to the
customer site (by Chart or an authorized distributor).
