摘要:
Disclosed is a reaction vessel handling apparatus adapted for use in a biological fluid testing apparatus. The reaction vessel handling apparatus includes an incubation member and wash member that are overlapping. A transfer device transfers reaction vessels between the incubation member and wash member at the overlapping portions. Incubation and wash members may be rings. Testing apparatus (e.g., immunoassay apparatus or clinical analyzer apparatus) including the reaction vessel handling apparatus and methods of operating the apparatus are provided, as are other aspects.
摘要:
Disclosed are systems and apparatus adapted to control a temperature of a process liquid in a metering line of an instrument. In one aspect, a temperature-controlled liquid delivery apparatus has a pre-flux member operable to control a first temperature set point SP1 of the process liquid in a flow path between a feed tank and a metering apparatus, a metering line connecting the metering apparatus and a probe, and a line flux member directly thermally coupled to the metering line and operable to control a second temperature set point SP2 of the process liquid contained in the metering line. Methods of operating the system are provided, as are other aspects.
摘要:
A sample tube transport system that includes a track adapted to provide a path for one or more carriers between a plurality of modules. The system includes at least one upper conveyor system having an upper belt configured to wrap around a first upper pulley and a second upper pulley, and a plurality of upper magnets affixed to the upper belt to move the one or more carriers along the track adjacent the upper belt. The at least one lower conveyor system includes a lower belt spaced vertically below the upper belt and configured to wrap around the first lower pulley and the second lower pulley, and a plurality of lower magnets affixed to the lower belt. Each of the plurality of lower magnets are positioned to attract and move the one or more carriers along the track adjacent the lower belt.
摘要:
A random access, high-throughput system and method for preparing a biological sample for polymerase chain reaction (PCR) testing are disclosed. The system includes a nucleic acid isolation/purification apparatus and a PCR apparatus. The nucleic acid isolation/purification apparatus magnetically captures nucleic acid (NA) solids from the biological sample and then suspends the NA in elution buffer solution. The PCR testing apparatus provides multiple cycles of the denaturing, annealing, and elongating thermal cycles. More particularly, the PCR testing apparatus includes a multi-vessel thermal cycler array that has a plurality of single-vessel thermal cyclers that is each individually-thermally-controllable so that adjacent single-vessel thermal cyclers can be heated or cooled to different temperatures corresponding to the different thermal cycles of the respective PCR testing process.
