Linde Cryogenics Supplies First of Kind Helium Recovery System to Sumitomo Cryogenics

In late March, Linde Cryogenics (CSA CSM) delivered a modular helium recovery system to Sumitomo Cryogenics of America, Inc's (CSA CSM) Allentown PA production facility. By capturing and recycling helium from production operations, the system is expected to reduce consumption of purchased helium at the facility by 70%. The system...

SLAC Researchers Use Cryo-EM to Discover Giant Cavity in Key Tuberculosis Molecule

Researchers from the Department of Energy’s SLAC National Accelerator Laboratory using Cryo-EM technology have discovered a strange new feature of a protein that’s thought to be important in the treatment of tuberculosis. The protein contains a highly unusual “huge” interior pocket that appears capable of passing a wide range of...

Champaign-Urbana MTD Purchases Two Hydrogen Buses

The Champaign-Urbana Illinois Mass Transit District (MTD), has ordered two hydrogen fuel cell buses from New Flyer of America. The contract calls for New Flyer to supply two hydrogen fuel cell electric sixty-foot Xcelsior CHARGE H2™ heavy duty transit buses in the Champaign, Urbana and Savoy regions of the state....

Infertile Cancer Survivor Gives Birth Using Frozen, Lab-Matured Egg in Scientific ‘Breakthrough’

In a world first, a French woman has given birth after freezing, thawing and fertilizing her immature eggs in a procedure called in vitro maturation, according to a study published in the journal Annals of Oncology. Doctors say this development "is particularly important for cancer patients, but it’s also a...

Quantum Design and Sumitomo Cryogenics of America Announce Collaboration with Helium Compressor

Developed jointly by Quantum Design and SHI Cryogenics (CSA CSMs), the new R-98 double inverter-driven helium compressor, the first in SHI’s new Revolution™ Series, is compatible with a range of their Gifford-McMahon and Pulse Tube two-stage cryocoolers. It represents the latest in “energy smart” helium compressors that reduce the operating...

Grand Opening Soon: ITER’s Cryostat Base

The first cryostat is being installed at the ITER Tokamak pit for the French fusion project at Saint-Paul-les-Durance. The cryostat base, part of the insulating vessel that encases the ITER Tokamak, is the heaviest of all the machine's components. As the first of four cryostat sections to be lowered into...

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...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
