摘要:
A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g. −80° C. or −135° C.) or cryogenic (e.g., about −140° C. to −196° C.) storage and retrieval system that stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are normally stored within an ultra-low temperature or cryogenic freezer compartment. The tube picking mechanism includes a tube picking chamber that is maintained at about −80° C., about −135° C. or at cryogenic temperatures in cryogenic applications. Active electrical and mechanical components are maintained in a compartment above and separate from the refrigerated, ultra-low temperature or cryogenic compartment. Thermal stratification inhibits heat transfer into the lower, ultra-low temperature or cryogenic compartment in which tube picking occurs from the upper compartment in which active electrical and mechanical components are located, and also inhibits heat transfer into the lower, ultra-low temperature or cryogenic compartment via an access door for tube storage racks.
摘要:
A storage cassette including a plurality of generally vertical compartments for storing sample tube racks and/or SBS formatted plates is constructed to be flexible along its substantially vertical axis thereby facilitating reliable robotic placement and retrieval of the cassette from nesting tubes located within a horizontal freezer compartment. Insulated walls and solid shelves minimize heat transfer from storage racks or plates placed in the storage cassette when the cassette is removed from an ultra-low temperature or cryogenic freezer. The outer walls of the cassette includes mechanical indexing locations to ensure appropriate positioning when robotically removing storage racks or plates from the cassette.

摘要:
An automated storage and retrieval system stores containers, typically containing biological or chemical samples, at ultra-low temperatures, i.e., from about −50° C. to about −90° C., preferably about −80° C. under normal operating conditions. A robot automatically places sample storage containers in stationary storage racks within the freezer compartment. Magnetic couplings are used to transmit mechanical power from outside of the freezer compartment to the robot inside of the freezer compartment. The robot has a simplified mechanical configuration.

A laboratory capper, decapper or combination capper/decapper includes a deck containing with a nest designed to hold an SBS-formatted tube storage rack, and a bit exchange magazine assembly containing one or more sets of adapter bits. The adapter bits are mounted on and unloaded from motor driven fittings, and are exchanged in order to cap or decap laboratory sample tubes or vials that have different head configurations. The bit exchange magazine assembly enables the bit to be exchanged robotically.
摘要:
A rack robot lifts and transfers sample tube storage racks or plates with a refrigerated enclosure maintained, e.g., at −20° C. The samples are normally held in ultra-low temperature, e.g., −80° C., or cryogenic freezers. From time to time, the racks or plates need to be roved from the ultra-low temperature or cryogenic freezers for processing and the rack robot transfers the racks or plates to the various processing stations within the refrigerated enclosure, such as tube picking, barcode reading, or frost removal stations.
摘要:
A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g., −80° C.) storage and retrieval systems which stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are loaded into trays located within an ultra-low temperature freezer compartment (−80° C.). A tube picking mechanism resides in a tube picking chamber that is located adjacent the freezer compartment. The tube picking chamber is maintained at about −20° C. when the tube picking mechanism is in operation. The tube picking mechanism includes a cache within the tube picking chamber to facilitate fast paced shuttling of the tube racks from the freezer compartment into the tube picking chamber. The shuttle has a clamping mechanism to secure a tube rack in place when a gripper head picks a tube from the rack. The system also includes a push pin that pushes on the bottom of the respective tube as it is being picked from the tube rack. A one-dimensional bar code reader is included within the tube picking chamber. The gripper head is able to move vertically and rotate within the field of view of the one-dimensional bar code reader in order to facilitate identification and reading of one-dimensional bar codes located on the sidewall of picked storage tubes. The system also uses fans to facilitate efficient cooling of the tube picking chamber.
