A cryostorage device (100) is described that includes at least one data storage device (200) and at least one sample receptacle device (300) with at least one sample chamber (301, 302, etc.) for the uptake of a suspension sample, the at least one sample chamber (301, 302, etc.) being connected to the data storage device (200) and having a elongated, hollow shape that extends from an inlet end (320) over a predetermined length to an outlet end (330) and being attached to the at least one data storage device (200) in a flexible and movably hanging manner.
摘要:
The invention relates to a cooling apparatus, especially for cryogenically preserving biological samples, comprising a duct (5) for delivering a coolant (3) to a cooling chamber (1), a heater (6) that has an adjustable first heating performance (P2) for heating the coolant (3) delivered to the cooling chamber (1), a first temperature sensor (8-10) for measuring the temperature (T2-T4) in the cooling chamber (1), a second temperature sensor (7) for measuring the temperature (T1) of the coolant (3) delivered to the cooling chamber (1), and a regulator (11) for regulating the temperature. Said regulator (11) is embodied as a multiple regulator which detects several temperatures (T1-T4) as control variables and/or adjusts several heating performances (P1, P2) as manipulated variables. The invention further relates to a corresponding operating method.
摘要:
The invention relates to a device and method for handling a probe, in particular, for treating, examining, inserting or extracting a cryoprobe. According to the invention, said probe is surrounded by an ambient gas, during handling, and an air-conditioning device (33) cools, dries and/or at least partially replaces the ambient gas by a protective gas, in order to prevent deterioration of the probe by the ambient gas during handling.
摘要:
A method for moving a probe (10, 91) through a cell material (20), which is formed from biological cells (21), is described, the probe (10) displacing the cells (21) without injury. A probe (10, 91) for performing the method and a cell manipulator, which is equipped with at least one probe of this type, are also described.

摘要:
The invention relates to a cooling device (1) for cooling an item to be cooled, especially for use in the examination, handling and processing of cryogenic samples. The device includes a cooling compartment (3) for receiving the item to be cooled, an inner wall defining the cooling compartment (3), an outer wall, a space between the outer wall and the inner wall, and a coolant feed line (11) for feeding a coolant. According to the invention, the coolant feed line (11) leads into the space between the inner wall and the outer wall and feeds the coolant into the space, the inner wall being permeable for the coolant.
