摘要:
A containment apparatus for liquids. The device may be used with nephelometric instruments to contain sample liquids for serial dilution. The containment apparatus includes a tray section having a plurality of wells formed as an integral part of the tray section. The wells include well portions extending from the tray section such that the well portions are insertible into holes in the turntable rim to secure the tray section to the rim.

A storage and retrieval system is provided. The storage and retrieval system having a frame and a shuttle movable within the frame, the shuttle having a carriage extending at least partially between a top and bottom of the frame. At least one tension member extends between a first and second ends of the frame and is coupled to the shuttle. At least one drive member extends between the first and second ends of the frame and is coupled to the shuttle. The at least one drive member and the at least one tension member project from opposite sides of the shuttle towards respective first and second ends of the frame and effect stabilization of the carriage against at least rotation relative to the frame. The at least one tension member crosses the at least one drive member and the at least one drive member effects movement of the shuttle.

An automated storage system for storing large quantities of samples in trays includes a storage compartment, a tray shuttle compartment abutting the storage compartment on one side and a plurality of independent modules on the other side. The modules perform processing of samples that are retrieved from the storage compartment by a tray shuttle, including extraction of selected samples from retrieved source trays and transfer of the selected samples into a separate, destination tray that can be further processed or removed from the system for use. The independent operation of the modules permits handling and processing to be performed simultaneously by different modules while the tray shuttle accesses additional samples within the storage compartment. In one embodiment, a vertical carousel is used to vertically align a desired tray with the tray shuttle, while the tray shuttle operates within a horizontal plane.

摘要:
Automated drug discovery protocols, or partially automated protocols, in which matrices with memories serve as the platform on which all manipulations are performed or serve as the repository of information that is transferred to other memories as the synthesized compounds are processed and screened. Also provided are automated drug discovery units for use in the protocols. The units provide a means for seamless data tracking and include instrumentation and vials with memories for information transfer to other memories in a unit. The units, which are provided herein, include some or all of the following: an automated or manual sorter, microvessels, which contain memories, an automated or semi-automated synthesizer, a microvessel washer/dryer, a manual or automated cleaver for removing compounds from the matrix with memory microvessels, and associated software. The memories may be any of any type, including electromagnetically encodable memories and optical memories, or combinations thereof. The memories may be pre-encoded or may be encodabie during, after or before processing. Also provided are manual and automated methods for sorting matrices with memories.

A method and apparatus for conveying liquids to and from a reaction cell in an automated sample handling apparatus. The conveyance apparatus includes a track and car system. A method and apparatus is disclosed which precisely positions the cars on the track. This positioning method and apparatus includes a plurality of apertures and spaces on the track of a size and spacing to allow the cars to accurately position themselves.
摘要:
In a system which measures a parameter of a sample and displays information relating thereto, a circuit including the component elements of the system for testing signal levels at test points within the system and for displaying the test signal levels. Switching means places the system in either a transducing mode for measuring the parameter or in a combined transducing/self-testing mode for simultaneous testing during transducing operation. The testing circuit includes an operator manipulated probe for contacting any of the test points and an analog multiplexer input of the system for multiplexing the probe test signal and the transducing signal. The multiplexed signals are converted to digital form and processed by the system's computer for display. In the combined transducing/self-testing mode, the probe test signal information is outputted to the system display while the transducing output thereto is inhibited. The transducing output information derived during testing is processed and stored by the computer for subsequent display.
摘要:
Titration apparatus for measuring chloride electrolyte in blood samples including a pair of coulometric generator electrodes for titrating the chloride with silver ions to precipitate silver chloride and a pair of amperometric detector electrodes for detecting completion of the silver chloride precipitation. The amperometric electrodes and one of the coulometric electrodes (cathode) are contained in a unitary electrode module which is mounted separately from the remaining coulometric electrode (anode) and which is readily removable for cleaning.
