摘要

Cryogenic devices are provided in which solid carbon dioxide (dry ice) is used to maintain a temperature zone in which samples can be manipulated under conditions in which the sample is maintained at a temperature below −50 C.

主权项

1. A system for cryogenic processing comprising:
(a) a container comprising an insulated chamber, said chamber comprising
i) a chamber floor,ii) at least one chamber wall,iii) a chamber opening above the chamber floor, said opening suitable for introduction of samples into the chamber; and (b) at least one gas permeable dry-ice retainer vertically disposed within the chamber and positioned to permit direct access to the chamber floor through the chamber opening, wherein the at least one gas permeable dry-ice retainer divides the chamber into
i) a sample-holding portion comprising at least part of the chamber floor, andii) at least one dry ice retention space.
