Patented Vapour Phase LN2 Storage Tanks - Labor İldam
CBS isothermal freezers feature a patented liquid nitrogen jacket to provide uniform storage temperatures in the -190ºC range, free from liquid nitrogen contact.
In the year 2000 CBS patented the first -190ºC dry storage system. This new storage system uses the same vacuum insulated vessel as conventional LN2 freezers, but instead of the liquid nitrogen being in the sample storage space of the freezer, it is in a patented liquid nitrogen jacket in the wall of the freezer. This liquid nitrogen jacket produces a unique vapor circulation in the freezer. This vapor circulation, in combination with the convection from the freezer walls, produces a very stable temperature in the -190ºC range without the large vertical temperature gradients found in traditional vapor phase LN2 storage tanks. The minimal temperature gradient and lack of liquid nitrogen in the bottom of the vessel mean that the full internal volume of each freezer is available for storing samples at liquid nitrogen temperatures, making the most efficient use of capacity.
