Provided is a temperature control system applied to an apparatus for analyzing a sample using a pipette nozzle and a reaction container, including a pipette tip temperature controller that heats a pipette tip which is fitted on the pipette nozzle and aspirates or discharges liquid and a reaction container temperature controller that heats the reaction container. The pipette tip temperature controller heats, in a concentrated manner, at least a distal end portion of the pipette tip of the pipette nozzle located at a predetermined heating position with hot air emitted from a heat source and is configured such that a distal end is capable of arriving at the reaction container by lowering the pipette nozzle from the heating position.

A tissue processing device includes a cassette for carrying tissue; a cassette container in which the cassette is received; a working stage, the cassette container being movably disposed on an upper side of the working stage; and an elastic vessel disposed on a lower side of the working stage, wherein the working stage defines a through hole, the cassette container communicates with the elastic vessel by means of the through hole, and each elastic vessel is configured to squeeze a reagent contained therein into the cassette container when the elastic vessel is deformed and to suck the reagent from the cassette container into the elastic vessel when the elastic vessel is restored. When the elastic vessel is deformed, the reagent therein is squeezed into the cassette container so that the tissue is immersed by the reagent, and when the elastic vessel is restored, the reagent contained in the cassette container is sucked into the elastic vessel to release the tissue from the reagent, so as to process the single tissue by means of a unique solution to prevent cross-contamination.

Method and apparatus are provided for processing a sample on a slide. A capillary processing module has a crank to raise and lower a slide, and/or a side inlet to apply a fluid to the slide. A capillary gap is formed between the slide and a chamber floor of the capillary processing module when the crank has lowered the slide. Capillary action causes the fluid to spread through the capillary space across a processing area and to contact the sample. When the crank raises the slide, the fluid is withdrawn from the processing area of the slide because the capillary gap is eliminated.

Systems and methods for probe tip heating are disclosed. An exemplary system for probe tip heating can include an enclosure enclosing a probe tip, a heating device, and a fan. The probe tip can be configured to access an internal volume of a stoppered container and to aspirate or dispense a material from or to the internal volume of the stoppered container. The heating device can be configured to heat air circulating within the enclosure. The fan can be positioned to circulate air within the enclosure to heat the tip of the probe

A diagnostic device has a sample probe for receiving sample material from one or more containers, a sample line for delivering the sample material to one or more reaction containers, a reagent supply and reagent supply line for supplying reagent to the one or more reaction containers, an incubation ring for receiving the reaction containers and incubating a mixture of the sample material and the reagent for a period of time, and a heating system for heating one or more areas or components of the device. The heating system has one or more positive temperature coefficient heaters.

The object of the invention is to avoid a decrease in dispensing accuracy of a sample, a reagent, or the like as a temperature changes. In an automatic analyzer, a dispensing nozzle sucks the sample from a sample container holding the sample and discharges the sample to a reaction container. A syringe pump controls an amount of change in a volume of water. A first pipe connects the dispensing nozzle and the syringe pump. An electromagnetic valve flows or stops the water. A second pipe connects the electromagnetic valve and the syringe pump. A branch pipe branches the water. A third pipe connects the electromagnetic valve and the branch pipe. A case accommodates at least the syringe pump, the first pipe, the electromagnetic valve, the second pipe, the branch pipe, and the third pipe. Further, the third pipe includes a heat exchange unit that performs heat exchange of the water.

A switching valve includes a rotor having a pair of rollers rotatably mounted on both ends thereof, a rotor drive unit rotationally driving the rotor, a pair of pressing members, each being provided at a position where each of the pair of pressing members cooperates with each of the pair of rollers outside a revolution orbit of each of the pair of rollers revolving by rotation of the rotor, and a pair of tubes, each being disposed between the revolution orbit of each of the pair of rollers and each of the pair of pressing members. A rotation center axis of the rotor is disposed on a straight line connecting centers of rotation of the pair of rollers, and each pressing member has the pair of pressing areas symmetrical with respect to a straight line passing through the center of rotation of the rotor and extending a vertical direction.
