Device and method for monitoring the temperature of a cryopreserved biological sample
The invention relates to a method for monitoring the temperature of a cryopreserved biological sample. The invention also relates to a device for monitoring the temperature of a cryopreserved biological sample. The device (10) for monitoring the temperature of a cryopreserved biological sample comprises a sample container (1) having a receiving space (2) for receiving a biological sample (6). The device also comprises at least one chamber (11) having an interior that is not fluidically connected to the receiving space (2) and is only partially filled with an indicator substance (7) with a melting temperature in a region of −20° C. to −140° C. The chamber (11) has a barrier (13) that causes the indicator substance (7) to move into a second sub-region (12b) of the chamber (11) when the indicator substance (7) in a first sub-region (12a) of the chamber is in the fluid aggregate state.
Method of storing and retrieving products using cryogenic storage rack with rotatable shelves
A storage rack for storing and retrieving products to be maintained at a desired cryogenic temperature is provided. The storage rack includes an elongate mounting bar carrying a plurality of shelves, and an elongate stop bar that extends generally parallel to the mounting bar. The shelves are independently rotatable relative to the mounting bar towards and away from the stop bar, thereby enabling alignment of all of the shelves when the storage rack is to be stored, and also enabling easy access to each of the individual shelves. A handle projects upwardly and horizontally in a curved configuration from the stop bar and the mounting bar to provide a gripping surface for moving the storage rack. The shelves receive cylindrical vial containers with threadably removable lids to make retrieval and replacement of sample vials quick to perform, thereby avoiding temperature-induced damage to other samples in the storage rack.
Closed and sterile container devices for cryopreservation and resuspension of body fluids
The disclosure provides for a container system and method for the cryopreservation and resuspension of a body fluid. The container system may include a cryopreservation container comprising the body fluid in a cryopreservation liquid, a resuspension container comprising a resuspension solution, a connection tube sterilely connecting the cryopreservation container and the resuspension container, and at least one shut-off element actively associated with the connection tube.
VITRIFICATION FREEZING CARRIER
Provided a vitrification freezing carrier includes a tube body of a hollow structure with an opened end provided with a matching part, a tube cap provided with a covering part of a hollow structure with one end closed and matching the matching part and provided with an extending part connected to the covering part, a carrying rod arranged on a side, facing an interior of the tube body, of the covering part and capable of extending into the tube body, and an auxiliary sampling mechanism including a carrier body provided with a locking part configured to be matched with the covering part to drive the covering part to move and an elastic reset assembly arranged on the carrier body and including a driving part and an elastic part driven by the driving part and capable of being selectively connected to the extending part in a matched manner.
Method of cryopreservation of stem cell-derived retinal pigment epithelial cells on polymeric substrate
Disclosed herein are methods and compositions for the cryopreservation of stem cells, such as stem-cell derived retinal pigment epithelial cells, that have been seeded onto and cultured on a substrate, such as a polymeric substrate. Such cryopreserved stem cells are useful for cell therapies, such as treatment of ocular damage or disease.
CRYOPRESERVATION DEVICES
Vial assemblies comprising a tubular body and a flexible bottom or flexible liner are described herein, wherein the flexible bottom or liner is configured to compress at least partially upon the application of force. Methods for storing and removing frozen samples from such vial assemblies are also described herein.
RFID ENABLED SPECIMEN HOLDER
A specimen holder includes a stick and an RFID tag. The stick is elongate along a longitudinal direction, and has a distal end and a proximal end opposite the distal end with respect to the longitudinal direction. The stick includes an outer surface and a distal portion of the outer surface that is closer to the distal end than the proximal end. The stick further includes an internal cavity that extends from a first terminal end to a second terminal end. The stick includes a midplane that is normal to the longitudinal direction, and the midplane is located equidistant between the distal end and the proximal end. The first terminal end, the second terminal end and an entirety of the internal cavity are all located between the midplane and the proximal end. The RFID tag is positioned within the internal cavity.
NEEDLE-LESS ACCESS VIAL AND CAP FOR THE ASEPTIC SAMPLING AND STORAGE OF LIQUIDS
According to an embodiment of the disclosure, a vial cap is configured for sealing attachment to a tube set and to a vial having a hollow interior configured for receiving and storing a liquid sample. The vial cap may comprise an axially extending cylindrical wall and a radially extending cap top disposed within the cylindrical wall, wherein the cap top has an upper surface and a lower surface. The vial cap may include at least two exterior tubes extending upwardly from the upper surface of the cap top, wherein each exterior tube defines a passageway configured to communicate with the tube set. The vial cap may further include at least two interior tubular structures extending downwardly from the lower surface of the cap top, wherein the at least two interior tubular structures each define a passageway configured to communicate with one of the exterior tubes and the hollow interior.
