Colorado fertility lab now protecting frozen embryos with CryoSentinel

The University of Colorado clinic has never suffered a tank failure. But, Colorado leaders wanted to do everything they could to protect frozen embryos and be sure that a similar catastrophic loss would never happen here.

“We are acutely aware that these tissues in our care represent the hopes and dreams for many people dealing with infertility, for those who stored sperm or eggs before cancer treatments and for young women preserving their eggs for future use,” said Dr. Liesl Nel-Themaat, director of the Colorado lab.

Thermographic Imaging: A Breakthrough Invention Providing an Effective and Reliable Cryogenic Storage Monitoring

This presentation was given by Dr. Zolt Peter Nagy as part of the International IVF Initiative lecture series.

Dr. Nagy is member of several national and international professional societies, including ASRM, ESHRE, Alpha. He is also board member of the International Society for Fertility Preservation (ISFP) and of the Alliance for Fertility Preservation (AFP) and past Chair of Alpha Scientist in Reproductive Medicine (ALPHA). Dr. Nagy is a reviewer of several medical journals, and currently he is section editor of RBMonline, past Section Editor of Human Reproduction. He has been an invited speaker in several hundreds of meeting/congresses in over 50 countries across the world. Dr. Nagy is author or co-author of over 200 publications, including several dozens of book chapters and five books.

Why liquid nitrogen immersion probes don't work during catastrophic dewar failure

This fun experiment, using Cryo Sentinel, demonstrates the effect of a sudden loss of vacuum on a vessel storing liquid nitrogen. Although the thermodynamics between this cheap vacuum flask and a cryogenic dewar are different this experiment shows very nicely what happens when a vacuum is lost.

We would love to talk to you about how Cryo Sentinel can be added to your monitoring solution.


Cryosentinel uses thermal imaging technology and an array of sensors to monitor your dewars and cryogenic vessels and will immediately alert you in the event of a vacuum failure.
