Kapillarsubstrat zur Tieftemperaturspeicherung von Suspensionsproben

Es wird eine Kryospeichervorrichtung (100) mit einem Traegerblock (10) beschrieben, auf dem mindestens eine kapillarfoermige Probenkammer (20) zur Aufnahme einer Suspensionsprobe angeordnet ist, so dass ein erstes Ende (21) der Probenkammer (20) am Traegerblock (10) befestigt ist und ein zweites, entgegengesetztes Ende (22) der Probenkammer (20) frei vom Traegerblock (10) absteht, wobei die mindestens eine Probenkammer (20) mit Abstand vom zweiten Ende (22) eine Druckausgleichsoeffnung (23) aufweist.

WO2004040975 A UPAB: 20040621 NOVELTY - A storage unit (100), for the preservation of suspended biological samples at very low temperatures, comprises a carrier block (10) to support a capillary sample chamber (20) on it with the suspended sample. DETAILED DESCRIPTION - A storage unit (100), for the preservation of suspended biological samples at very low temperatures, comprises a carrier block (10) to support a capillary sample chamber (20) on it with the suspended sample. One end (21) of the chamber is fixed at the block surface (11) and its opposite end (22) stands free of the block. A pressure compensation opening (23) is at a gap from the free end of the capillary and preferably at the fixed end, which can also act as a nominal fracture point. The carrier block can be fitted with a data store and a temperature sensor and/or a cold surface. USE - The unit is for the storage and preservation of biological samples at temperatures below neg. 100 deg. C, e.g. suspended cells, cell groups and cell components. It is used in cell biology and molecular biotechnology applications. ADVANTAGE - A large number of samples can be prepared for low temperature storage within a short time, and they can be removed easily and selectively.
