Container for freezing teeth

摘要

The tooth freezing container for cryopreservation of dental tissue samples (10), comprises uptake space for receiving a solution (12) to wash the sample, and a receiver arranged in the uptake space to keep the sample in a defined position during freezing. The uptake space has a wall made of a cryogenically stable plastic material with minimal heat conductivity and is accessible over an opening, which is sealably lockable after input of the sample by a locking element. The contact element is let into the side panel as cooling ring and/or into the bottom of the cylinder as a cooling plate. -The tooth freezing container for cryopreservation of dental tissue samples (10), comprises uptake space for receiving a solution (12) for washing the sample, and a receiver arranged in the uptake space to keep the sample in a defined position during freezing. The uptake space has a wall made of a cryogenically stable plastic material with minimal heat conductivity and is accessible over an opening, which is sealably lockable after input of the sample by a locking element. A metal contact element with high heat conductivity, is let into the wall at a position where the distance to the defined position is as small as possible. An exterior surface of the contact element is accessible from the outside and is arranged with direct contact to a cooler. The wall is designed as a cylinder with a round cross section, and the topside of the cylinder is open to form an opening. The cooling plate composed of metal (9) forms a bottom, above which the container is flatly placed above a correspondingly uniform contact element of the cooling plate. The cooling ring forms a collar projecting above the wall. The collar flatly rests upon the contact element of the cooler in the case of the container is inserted. The receiver is composed of an interrupted structure, which is formed as a single unit at the inner wall of the container and which guarantees the washing of the sample. The structure exhibits ribs that project into the uptake space and that run together as a dish-shaped receiver. The locking element exhibits a plug (6) from ductile rubber. The plug is covered by a flange cap (7) made out of sheet metal, which holds the plug sealably at the edge of the opening and grasps the collar surrounding the opening from behind. The flange cap exhibits a central opening, in order to facilitate the injection of a needle into the plug.
