GOW-MAC Instrument Company, introduces the process oriented Series AR710 and AR720 gas analyzers with High Frequency Argon Discharge Ionization Detector (HFADD).
At the CEC/ICMC Awards Breakfast on July 2, Ray Radebaugh received the prestigious Samuel C. Collins Award for “an individual who has made outstanding contributions to the identification and solution of cryogenic engineering problems and has…demonstrated a concern for the cryogenic community through unselfish professional service and leadership to this...
Immunovative Therapies, Ltd. recently announced that its New Drug (IND) application was cleared by the US Food and Drug Administration, allowing the company to begin clinical trials of its experimental CryoStim™ cancer vaccine product for the treatment of advanced metastatic solid tumors.
The 2009 Cryogenic Engineering Conference/International Cryogenic Materials Conference brought together almost 500 persons from all areas of cryogenics to exchange technology and ideas.
Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...
Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...
The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

You are encouraged to read Cryo Central’s History...
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...
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...
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...
I am writing a proposal to do some deep space simulations of mechanical vibrations at cryogenic temperatures. For the research, I will need to obtain a chamber that has a space of approximately 1700 cubic inches (or a 12in. cube) that also has an optical viewing window.
I am constructing a cryogenic generator for the Air Force. It operates at 15,000 rpm for Liquid Hydrogen. I need a rotating shaft seal that will work with liquid to gaseous hydrogen. Where can I source seals for this application?
