This invention relates to a sampling device. The device includes an elongate separating member having a sampling side and a non-sampling side. One or more through openings extend from the sampling side to the non-sampling side of the elongate member. The separating member is adapted for insertion into a reservoir of particulate material so as to define a sampling zone and a non-sampling zone within the reservoir. A shaft is positioned away from the sampling side and operably associated with the separating member, wherein the shaft is selectively rotatable about its longitudinal axis. One or more sample capturing scoops are attached to the shaft so as to be aligned with a respective opening. The or each scoop has a leading edge, a trailing edge and a cavity for receiving a sample of particulate material. The device is configured such that rotation of the shaft about its longitudinal axis causes a corresponding rotation of the or each scoop between a first position and a second position. In the first position, the leading edge of the associated scoop is located within the respective opening such that the opening is effectively closed and the remainder of the scoop projects away from the sampling side such that the sampling side of the separating member is free of protuberances during insertion into the reservoir. In the second position, the scoop is positioned on the sampling side and the leading edge of the associated scoop bears against the sampling side of the elongate member, thereby to enclose the sample of particulate material by the rotation of the scoop towards the second position.

An electrically passive device and method for in-situ acoustic emission, and/or releasing, sampling and/or measuring of a fluid or various material(s) is provided. The device may provide a robust timing mechanism to release, sample and/or perform measurements on a predefined schedule, and, in various embodiments, emits an acoustic signal sequence(s) that may be used for triangulation of the device position within, for example, a hydrocarbon reservoir or a living body.

Cell and organ (or tissue) cultures provide a micro-environment with respect to nutrients, gas exchange, and scaffolding in order to encourage specific cell function, and in some cases to mimic in-vivo cellular expression under in-vitro conditions. We describe apparatus and methods to chemically, spatially, and temporally measure diffusible molecules produced, or used by cells or tissues in culture. In this manner, mechanisms of cell-cell interaction and other chemical signaling, detailed biochemical pathways, and the action of potential pharmaco-therapy agents can be better understood at a molecular level. In addition to basic science, the technical advantages of process monitoring and control can be applied to optimize culture products in bioreactors. Embodiments of this device are intended to simulate and monitor [input and output] the behavior of vascular capillary beds in higher species vascular systems.
