Abstract: According to various implementations, the bioreactor system includes a bioreactor vessel, an impeller for stirring contents within the vessel, a temperature control source for controlling the temperature of the contents of the vessel, an aeration system for supplying air to the vessel, and one or more data loggers. According to certain implementations, the impeller is a novel impeller design that spins more smoothly and rapidly than known impellers. In addition, the bioreactor system is modular, durable, and relatively inexpensive compared to existing bioreactor systems, which allows for bench-scale implementation, use with differently sized bioreactor vessels, and accessibility to more educational programs, according to some implementations.

Abstract: Provided is a test apparatus in which a test for bacterial identification or antimicrobial susceptibility can be promptly determined. A division state of bacteria is monitored by performing microscopic observation of shapes and the number of the bacteria in each of wells in a culture plate for bacterial identification culture or an antimicrobial susceptibility test, and it is determined whether or not the bacteria grow in a stage shifted from an induction phase to a logarithmic phase, with reference to an image obtained through microscopic observation. In addition, determination performed based on turbidity in the related art may be combined with determination performed based on microscopic observation in which change and the like in the shapes of the bacteria are monitored. Accordingly, it is possible to realize a highly accurate test result.

Abstract: 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.

Abstract: The invention relates to a probe for measuring the biomass content in a medium having a suspending fluid and cells. The probe has at least three electrodes, wherein two of the electrodes are configured as excitation electrodes for transmitting an excitation signal through a medium. Two of the electrodes are configured as signal electrodes for receiving an excitation signal that has passed through the medium. The or each signal electrode is located between the two excitation electrodes at a position where a high current density is generated. The probe can have two excitation electrodes and four signal electrodes. The signal electrodes are configured substantially in parallel and arranged in couples adjacent each other, at positions between the excitation electrodes.
Abstract: According to one embodiment, a specimen measurement apparatus includes a detector, a reaction promoter and processing circuitry. The detector generates an electrical signal based on a reactive state in a reaction chamber in which a mixture of a test substance and a reagent is contained. The reaction promoter supplies to the reaction chamber energy to promote reaction in the reaction chamber. The processing circuitry switches an energy supply state in accordance with a predetermined time schedule, determines a stationary state of the test substance based on an electrical signal generated after the energy supply state is switched, and outputs the stationary state obtained by the determination.
Abstract: A single-use bioreactor is provided.
