Intermediate temperature storage

Intermediate temperature storage (ITS) is the long-term care (storage) for cryonics patients in a temperature warmer than liquid nitrogen temperature (−196 °C), but colder than the glass transition temperature of the vitrification solution being used (such as −123 °C for M22 ). Methods for creating ITS are being researched, because liquid nitrogen is too cold for patients, causing fracturing.

ITS is being researched by the Alcor Life Extension Foundation and the European Biostasis Foundation. Alcor has a few neuropreserved ITS patients.
