Adiabatic Demagnetization Refrigeration
Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...
Cryogen-Free
A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...
Cryostats and Cryocoolers
A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...
Air Separation and Liquefaction

You are encouraged to read Cryo Central’s History...
Bose-Einstein Condensate
A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...
Cold Technology for Pest Control
While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
Cryogenic Finishing
The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
Colleges that offer cryogenic studies
Would you happen to know of any colleges in the US that offer cryogenics as a major? If not, should I major in something like biology or physics before, then branch off to the field of cryogenics? Any information that you could give me would be greatly appreciated, considering this...
Sudden loss of vacuum in LHe storage dewar
I’m trying to find data on what happens when a 100 Liter LHe storage dewar experiences a catastrophic failure such as a sudden loss of vacuum. If anyone has any info on this subject, it would be very helpful.
Data on hardness of Indium?
Where can I find experimental data on the hardness of Indium, as a function of temperature, as well as any existing data on the thermal contact conductance of junctions containing Indium foil, also as a function of temperature?
Company to design and manufacture a portable gas purity monitoring system
I am looking for a company to design and manufacture a portable gas purity monitoring system using a cryostat/dewar/flow meter combination.
