The present technology is directed to capillarity-based devices for performing chemical processes and associated system and methods. In one embodiment, for example, a device can include a porous receiving element having an input region and a receiving region, a first fluid source and a second fluid source positioned within the input region of the receiving element; wherein the first fluid source is positioned between the second fluid source and the receiving region, and wherein, when both the first and second fluid sources are in fluid connection with the input region, the device is configured to sequentially deliver the first fluid and the second fluid to the receiving region without leakage.

A tissue sample that has been removed from a subject can be properly fixed for evaluation using the disclosed transporter assembly for carrying a tissue sample and method for fixing an unfixed tissue sample. In one embodiment, the disclosed assembly includes a transport container, a fixative in the transport container, and a cooling device that reduces and/or maintains the temperature of the fixative to perform a pre-soaking process at a temperature of less than about 7° C. The pre-soaking process can, for example, be performed during sample transport or during extended periods of storage, such as over a weekend.

Described are various embodiments of a reactive chemical exothermic heating element and system. The exothermic chemical heating element has a reactive solid holder having a channel therein with an exposed end. A reactive chemical is disposed in the channel and able to exothermically react with a suitable liquid, contained in a first vessel. On exposure to the suitable liquid, a gas is generated in the channel and a gas bubble emerges from the channel thereby limiting further suitable liquid from accessing the reactive chemical, and thus controlling the rate of the exothermic reaction and the energy released over a given time period to the suitable liquid. A second vessel may be disposed in the suitable liquid so as to heat any contents of the second vessel via a liquid bath of the second vessel.

The endothermic syringe sleeve is an insulating storage structure. The endothermic syringe sleeve is configured to store a burette that contains an arterial blood samples. The endothermic syringe sleeve is configured to cool the arterial blood sample. The endothermic syringe sleeve is configured to store the arterial blood sample in the cooled state. The endothermic syringe sleeve comprises an endothermic sleeve and the burette. The endothermic sleeve forms a cooled environment within which the burette is stored.

The present invention provides a device and method for testing a material for the presence of DNA. The system includes a centrifuge, a microchip performing cell lysis and an enclosure that contains an isothermal ballast material and chromogenic agent that melts at a specific temperature and displays a color change, respectively.

The present invention relates to the use of warmers, or autonomous heat packs, for heating and maintaining a solution at a suitable temperature, for the period of time required to accomplish a chemical, biochemical or biological reaction, in particular in molecular biology or cell biology applications. Biology kits containing warmers are also part of this invention.

A system for the integrated and automated analysis of DNA or protein, including a single-use cartridge, with an analysis device having a control device, and devices for capturing and processing signals, the control device carrying out a completely automatic process and evaluation of molecular diagnostic analysis via single-use cartridges (Lab-on-a-Chip). Controlling of an analysis process, which occurs in the cartridge, involves the subsequent displacement and thermostatisation of liquids with a first device, and with a second device the signals which are obtained during the analysis are processed. The first and the second devices are synchronized in such a manner that the analysis process of the sample can be carried out in a totally integrated manner thus producing an immediate result.
