The apparatus includes a memory for storing the data, the memory in communication with the scanning mechanism patients. The apparatus includes a computer for identifying in the data cell aggregates in the samples from the samples that have been scanned with an ...

A transport system is provided for a sample testing machine. The transport system includes a carrier holding a set of test sample devices and a drive subsystem for moving the carrier through the sample testing machine. The drive subsystem includes a reciprocating motor-driven block engaging the carrier and moving the carrier back and forth in a predetermined longitudinal path extending along a longitudinal axis from an entrance station to a plurality of processing stations in the sample testing ...

A polymerization reactor having at least three side wall surfaces and a bottom wall surface forming a reservoir and at least one heat exchanger plate in fluid communication with a coolant source, wherein each of the at least one heat exchanger plate is disposed on a lid. The polymerization reactors of the present invention permit large amounts of polymer to be formed in each reactor batch. Preferably, polymers are formed in the polymerization reactor by bulk polymerization. Methods for forming p...

Without causing an increase in size and complication of an automatic analyzer, the efficiency of washing cuvettes can be increased and the amount of detergent used can be more effectively saved in comparison with known analyzers. In an automatic analyzer in which a sample and a reagent are dispensed into each of a plurality of cuvettes, a resulting reaction solution is mixed under stirring, and reaction states of the mixed reaction solution are measured successively. The automatic analyzer inclu...

A DNA probe synthesis system may include a target holder for holding a target chip, an ejector array chip, a wash and dry station, and conveyance means for moving the target holder and the chip between the ejector array chip and the wash and dry station. The ejector array chip may include ejectors, reservoirs for containing DNA bases, and microchannels all on the same substrate. The ejectors may be Self Focusing Acoustic Transducers (SFATs).

A fab can be constructed as a round or rectangular annular tube with a primary cleanspace located in-between its inner and outer tubes. The fab can be encircled with levels upon which tools can be densely packed while preserving unidirectional air flow. If only tool ports are inside, and robotics are used, primary cleanspace size can be minimized. Highly simplified robotics can be used. Tools can be removed and repaired centrally. A secondary cleanspace can be added for tool bodies. Multilevel c...

A sample-conveying system has first and second conveying paths which are separated from each other. A first transition base is located at a conveyance terminal end portion of the conveying path. A second transition base is located at a conveyance starting end portion of the conveying path. A mobile unit moves between the first and second conveying paths. The transition base is provided with a receptacle carrier and a rack carrier. The receptacle carrier transfers receptacles on the conveying pat...
