A recently granted patent (Publication Number: US11813614B2) discloses a system for cryogenic processing that includes a container with a perforated retainer to divide the interior chamber into a sample-holding portion and a dry ice retention space. The system is designed to maintain the sample-holding portion at a temperature below -50° C. for at least four hours without requiring additional dry ice, even when the container is in a room at 25° C. with the chamber opening constantly open for user access. The container is modular, made of a material with low thermal conductivity, and can accept different retainers with varying properties.

Furthermore, the system includes features such as a cover for the chamber, temperature sensors, a microprocessor for monitoring and alarm systems, and a laser for marking the upper boundary of a low-temperature zone. The perforated retainer is constructed from aluminum with gas-permeable slots and can be easily inserted and removed. Additionally, the system allows for manipulation of samples under cryogenic conditions in the sample-holding portion, which is free of dry ice pieces, while the dry ice retention space contains dry ice for maintaining the required temperature. Overall, the system offers a versatile and efficient solution for cryogenic processing with advanced temperature control and monitoring capabilities.
