Abstract:
The present invention discloses sample thawing devices, systems, and methods, that are configured to take individual 10 mL to 50 mL sample vials and to thaw the contents of such vials. The contents of such relatively large gauge vial are samples with cells, and the thawing of such samples is based on the temperature, volume, and mass of the sample in order to evenly distribute heat and avoid ice crystallization damage to the cells during thawing. A multi-part heater block lined with a thermally-conductive compliant material may be molded to a shape of a vial so as to fittingly mate with known vial sizes. The heater block is capable of separating into three or four segments, providing for ease in inserting and removing samples. The heater block segments can be moved linearly along a tractor, or tilt along a hinge, to move between inward and outward positions.
Abstract:
A system, method and kit for preparing a cellular biological sample are disclosed. In a particular embodiment, the disclosed system (200) is configured to mate with a substrate (208), such as a microscope slide, and provide the fluidics that can be used to perform a particular sample preparation protocol. The disclosed system is particularly suited for use in a point-of-care setting, such as in a surgical suite or in a resource-limited or remote setting where automation of the sample preparation protocol is not a viable alternative.
Abstract:
Examples include polymerase chain reaction (PCR) devices. Example PCR devices comprise a fluid input, a fluid output, and a set of microfluidic channels that fluidly connect the fluid input and the fluid output. Each microfluidic channel comprises a reaction chamber, and examples further comprise at least one heating element, where the at least one heating element is positioned in the reaction chamber of each microfluidic channel. The at least one heating element is to heat fluid in the reaction chamber of each fluid channel, and the at least one heating element is to pump fluid to the reaction chamber and from the reaction chamber of each microfluidic channel.

Disclosed are specimen processing systems capable of processing specimens carried on slides. The specimen processing systems comprise opposables having at least one fluid control element (1500, 1501, 1502).

Abstract:
Fluidic devices and methods involving incubation and/or mixing of assay components are provided. In some embodiments, a biological and/or chemical assay may be performed in a fluidic device. The fluidic device may be designed to allow for controlled incubation and/or mixing of two or more assay components. In some such embodiments, the fluidic device may comprise an incubation channel having a relatively large cross-sectional dimension in fluid communication with a detection channel. The incubation channel may allow for adequate mixing and/or incubation of two or more assay components prior to analysis of the assay. In certain embodiments, the detection channel may be used to provide feedback on the extent of incubation and/or mixing. Based on the feedback, one or more component of the fluidic system may be regulated to allow the requisite degree of mixing and/or incubation to be achieved. In some embodiments, the controlled incubation and/or mixing of assay components in an incubation channel, as described herein, may allow for improved assay performance.
