Cryogenic Storage Freezers

MVE HEco Series Freezers
The MVE HEco Series freezers provide best-in-class liquid
nitrogen utilization efficiency. The streamlined liquid nitrogen
plumbing system and included vacuum-jacketed transfer
hose significantly reduce liquid nitrogen transfer losses. In
addition, the MVE HEco freezers enclose all electronics and
plumbing beneath hinged work surfaces at the top of the
freezer. These work surfaces provide convenient locations to
place a rack, box, or other item. The MVE HEco freezers are
intended for vapor-phase sample storage with the samples
placed above a liquid nitrogen reservoir at the base of the
unit. These freezers provide -190 °C temperatures at the
top boxes in the storage racks. MVE cryogenic storage
freezers provide industry-leading storage density, hold time,
and sample security.
