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.

DOE Funds International Cryogenic Dark Matter Experiment, Construction Underway at Canada’s SNOLAB

The US Department of Energy Office of Science and the National Science Foundation have approved funding and the start of construction for the SuperCDMS SNOLAB experiment, that will begin in the early 2020s to hunt for light dark matter particles. DOE’s Fermi National Accelerator Laboratory (CSA CSM) will play a...

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.

Regenerators

Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...

Pulse Tube Cryocoolers

The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...

Thermal Expansion

Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...

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...

Dry ice vs. LN2 for preserving tissue

I was wondering if anyone could provide feedback/data on whether it is best in terms of preserving tissue quality to freeze tissue in OCT using dry ice versus liquid nitrogen?

Are there lists of existing biorepositories?

We are a relatively new Biorepository that was developed as part of a large breast cancer epidemiology study, and thus far we have accumulated DNA on over 8000 women along with extensive questionnaire, mammography, and case status data. I was wondering, are there lists of existing Biorepositories with their contents?...

Heat flux value for inner vessel when vacuum insulation fails

To size a relief valve for a LN2 cryostat I have to know “worse case” boil-off rate when vacuum insulation failed and inner vessel with LN2 is in direct contact with room temperature air at 300K. So, I am looking for a heat flux value (watt/m2) to LN2 inner vessel...

Trying to design a system to store ammonia at -33°C

I am working on a project where we are trying to design a system to store ammonia at -33°C. In order to size the compressors to maintain the ammonia in the liquid state, I need to estimate the heat gained from the environment including the radiation from the sun and...
