Controllable Isothermic Vapor Storage (CIVS)
Storing samples submerged in Liquid Nitrogen creates sample cross-contamination issues and personnel hazards.
Storage in Liquid Nitrogen Vapor avoids these major problems, but results in extreme and uncontrolled temperature excursions, and provides no meaningful knowledge of sample thermal history. Historically Conventional LN2 vapor storage been plagued by severe locational temperature gradients inflicting repeated expansion & contraction stress on stored samples.
Ultra-low temperature compressor type freezers are costly, noisy, emit heat to their external environment, must be kept in air conditioned space, and warm quickly upon power failure.
Now there is a new form of Liquid Nitrogen Vapor storage that eliminates the problems associated with conventional LN2 vapor, LN2 immersion, and ultra-low temperature mechanical freezers. Controllable Isothermic Vapor Storage (CIVS)
Our fully programmable CIVS units are ideal for static temperature storage as well as for applications requiring time/temperature profiling. Easy to maintain, patent protected CIVS units have very low power requirements, and need no external environmental control or backup electrical generation. The units emit no heat to the surrounding environment, are portable, and are supplied with computer interface capability. If electrical power to this unit is interrupted the unit will get colder, not warmer, thus providing another layer of sample protection.
Every CIVS unit is custom built to your size specifications and usage requirements. Customizable storage racks, canisters and frames are available for any “bio logistic” or research application, offering easily accessible space and cost efficient storage. CIVS units are rugged and come with a three-year warranty on vacuum and electronics.
