How Lake Shore Cryotronics is Helping Reduce Helium Costs in The Lab

Lake Shore Cryotronics’ Director of Product Management for Cryogenic Systems Rachael Floyd shares how Lake Shore Cryotronics is helping reduce helium costs in the lab. Why is the availability of helium becoming a pressing concern for research labs, and what unique challenges does it pose? The high cost of helium is a big...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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...

Looking for manufacturers of cryogenic dewars with infrared detectors (long wave)

We are looking for manufacturers of cryogenic dewars with infrared detectors (long wave). We need these dewars for repairing infrared systems (thermographic systems) and we cannot find such glass dewars. Do you know any manufacturers’ addresses?

Manufacturers of cryogenic regenerator lead spheres?

Would you please suggest a few manufacturers that produce cryogenic regenerator lead spheres? The size we need is 0.15mm-0.2mm. I don’t have a lot of ideas for where to go to purchase them.

Assistance with resolving a sealing problem?

We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...
