Abstract
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.
Claims22
A system for cryogenic processing comprising:
- a container comprising a bottom, a first side, a second side, and a third side forming an interior chamber with an open top, the bottom having an interior floor surface, the first side having a first interior side surface, the second side having a second interior side surface, and the third side having a third interior side surface;
- and
- a perforated retainer including a first perforated portion, a second perforated portion, and a third perforated portion, the perforated retainer configured to be positioned in the interior chamber such that the first perforated portion is adjacent the first interior side surface and the second perforated portion is adjacent the second interior side surface to divide the interior chamber into a sample-holding portion and a dry ice retention space, the sample-holding portion being between the first perforated portion and the second perforated portion, the dry ice retention space positioned on a first peripheral side and a second peripheral side of the sample-holding portion, perforations of the first perforated portion and the second perforated portion configured to exhaust gas directly into the interior chamber, the third perforated portion configured such that when the first perforated portion is adjacent the first interior side surface and the second perforated portion is adjacent the second interior side surface, then the third perforated portion is adjacent the third interior side surface and the dry ice retention space extends on a third peripheral side of the sample-holding portion,
- wherein the system is configured to allow for access to the interior floor surface of the sample-holding portion while maintaining the sample-holding portion at an equilibrium condition at a temperature below an ambient temperature.
