A shift and scan test tube rack apparatus and method comprised of an array of initially aligned racks each comprised of a row of spaced apart receptacles each having a receptacle window through which a barcode on a received barcode labeled test tube is viewable and each rack further comprised of a plurality of line of sight windows each interposed between two adjacent spaced apart receptacles, and a shifting device for individually shifting any one of the racks in the array of initially aligned racks to a shifted position that allows a plurality of the receptacle windows in the shifted rack to be viewed through the plurality of line of sight windows in the remaining aligned racks for reading barcodes on barcode labeled test tubes received in the shifted rack.

Shift and scan test tube rack apparatus and method

A probe head used in robotic assays for transferring liquid in miniscule quantities. The probe head includes an array of liquid transferring needles which move as a unit with the probe head. As the needles contact a surface, high spots or other irregularities on the surface are accommodated by needle compliance to assure all needles ultimately touch the surface. Touching contact assures reliable liquid transfer.

Ultra low volume probe

A sample treatment system for automated extraction of compounds is disclosed. The system includes a housing defining an enclosure including a top cover having open ended chambers to receive sample plates on an interposed carriage frame, an automated shuttle means for lateral transportation and vertical lifting of the carriage frame to selectively address the chamber below the sample plate for the throughpassage of fluid from the sample plate and urged by a vacuum pump for evacuating air from a chamber to a degree below atmospheric pressure for through passage of fluid from the sample plate to either a waste plate or a collection plate. The shuttle means includes motor drives for precisely laterally and vertically positioning the carriage frame.

Automated sample treatment system: apparatus and method

An automated assaying system is disclosed having a multiplicity of lumens oriented and controllable in clusters. The lumens are portrayed in a matrix, wherein each row of the matrix consists of one such cluster that is individually controllable for aspiration and dispensation purposes. Also provided is a unique wash system capable of flushing the entirety of the system. A method is also depicted for accomplishing this unique assaying.
