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.

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. Dry gas air flows are used to reduce moisture and the consequential frost within the freezer compartment. A custom insulated door is provided with an access module and a tube picking compartment as well as servo motors for controlling a robot within the ultra-low temperature freezer compartment. The 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. The custom door can be readily attached to standard freezer bodies.

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.

A manually directed, multi-channel electronic pipettor includes a software biasing mode to assure proper alignment over wells in the 96-well plate and the 384-well plate. The system also includes manual repositioning levers for nesting receptacles which are customized for 96 well-plates and 384 well-plates respectively.
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:
A system for monitoring and regulating pressure and concentration in a moving fluid stream inside of a conduit is provided. The fluid stream includes a first fluid. The system comprises an infusion assembly that includes a catheter having a series of holes distributed around an exterior surface and a pumping system for introducing a second fluid into said catheter to create a solution mixture. A data collection system is provided for collecting data indicative of pressure and conductivity values. Data from the data collection system is forwarded to a data processing and control apparatus. The data processing and control apparatus comprises conversion means for converting the measured conductivity into a concentration value and control means for controlling operation of the infusion assembly based on a comparison of selected values with data received from the data collection system. A user control and analysis system allows user interaction. The system allows complete automatic control over the fluid distribution within a fluid conduit in response to measured values.
