History of Spearlab Foam Dewars

Our durable foam dewars were developed at the Advanced Light Source, a synchrotron facility of the Lawrence Berkeley National Laboratory. The Lawrence Berkeley Lab is operated by the University of California, and receives federal funding from the Department of Energy.

The first application of these vessels was for the transfer and processing of cryogenic samples for x-ray crystallography measurements.  The foam vessels addressed the safety and performance problems inherent in low profile glass Dewar flasks. Filled with liquid nitrogen, such glass Dewar flasks are difficult to handle, and they shatter when dropped. This poses a serious hazard to personnel and equipment. Such accidents at LBNL have caused thousands of dollars of equipment damage, along with lost weeks of valuable research time.

In contrast, the patented (U.S. pat. no. 7,971,744) design of our foam dewar makes it easier to handle and safer to use than a traditional low profile glass Dewar. Also, because of its lower thermal mass, a foam vessel will cause less liquid nitrogen boiloff when it is filled. Additionally, it accumulates less frost during regular use, which can be a major problem with crystallography samples. With a foam dewar, less LN is consumed, and research proceeds more effectively.

Spearlab foam dewars have gained international acceptance as the preferred vessel for crystallography sample processing and transfer, being used in hundreds of laboratories worldwide. Our foam dewars also can be used in many other fields of research, industry, or education. If you have an application that involves cryogenics, please tell us your particular needs, so that we may help you to engineer a solution.
