A pre-heating unit (PH) 100 comprises a heater (101), a PH-body (102), a tube-like flow path (103), a heat conductor (104), and a cover (105). The PH-body (102) is heated by the heater (101). The tube-like flow path (103) is arranged in a groove (102a) and allows a liquid to flow. The groove (102a) is formed by extending in an axial direction with respect to an external peripheral surface (102b). The heat conductor (104) comprises a metal member covering the external peripheral surface (102b) and the tube-like flow path (103). The cover comprises an elastic member covering the heat conductor (104) and having a lower thermal conductivity than the heat conductor (104).

Provided herein are systems, devices, and methods for performing optical multianalyte detection in a sample, such as a human blood sample. The system processes sample in a single-use support pack that holds the blood sample and contains pipette tips, buffers, reagent preparation wells and a monolayer. Sample is transferred from the sample pack to a single-use disc consumable that contains microwells pre-filled with dried chemistries, plasma separation features, and a hematocrit channel. The instrument comprises a cell imager, an absorbance module comprising a spectrophotometer, a fluorescent laser scanning module, and a camera. The system uses only a small amount of blood from a single heparinized sample, to simultaneously provide results for a full panel of routine blood tests spanning elecochemistry, clinical chemistry, hematology, immunoassays and combinations thereof.

The present disclosure provides a device that may be used for a range of different assays such as immunoassays, nucleic acid analysis, metabolite analysis, clinical chemistry, and complete blood cell count. The device optionally contains a sample analysis region to analyze the samples processed in the device. The device comprises a top substrate bound to a bottom substrate wherein the top substrate bound to the bottom substrate forms two or more primary zones separated by one or more secondary zones, and wherein the top substrate has an opening in one or more of the primary zones.
