Brooks Expands Freezer Line to Support Cryobags

Brooks Life Sciences, a division of Brooks Automation (CSA CSM), announced the launch of its BioStore III Cryo automated freezer for 250ml cryobags at the International Society for Cellular Therapy Conference (ICCT 2018) in Montreal. The latest version of its freezer brings simple, automated management for 250mL cryobags to the...

UK Researchers Form First National Biobank

The UK’s National History Museum announced a new initiative to collect and preserve the DNA of thousands of animals at a biobank called CryoArks. The collection of zoological tissue will provide a central hub for researchers across the UK, according to the museum, providing access to cells and DNA from...

NOAA Reports Cooling Failure aboard GOES-17

The National Oceanic and Atmospheric Administration has reported a performance issue with the cooling system aboard GOES-17, a multibillion-dollar weather satellite launched in March. NOAA engineers encountered the issue during commissioning of the satellite’s Advanced Baseline Imager instrument.

Lake Shore Cryotronics Celebrating 50 Years

Lake Shore Cryotronics (CSA CSM) is celebrating 50 years in business this year, and in May it recognized the people who helped it become a worldwide leader in precision measurement over a wide range of temperature and magnetic field conditions.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

Need help with calculating flow rate

I have to maintain a certain mass (some tons) at 100 K by circulating in it GHe (through apposite channels). How can I calculate the flow rate needed? I suppose that the delta T (T inlet and T outlet) and the heat load on the mass are necessary. Knowing the...
