Abstract: Provided herein are containers for holding a portion of a biological sample such as a fecal sample. The containers include a body that can be sealed with an upper cap that is attached to a sampling pin and a grip member. The sampling pin is configured to collect a predetermined amount of sample in one or more sampling grooves, with excess sample amount optionally removed from the sampling pin by an interior flange of the container body. The grip member is configured to provide the user of the container with improved torque and grip, and to distance the fingers of the user from the sample being collected. Also provided are kits and methods including the disclosed containers.

Abstract: Provided herein are analyzers as well as related methods for measuring both an absorbance and emission of a sample. The analyzer includes light sources for epi-illumination and transillumination of the sample, and detectors for measuring the intensities of excitation, emission, and transillumination light. A dichroic mirror permits a portion of the excitation light to transmit to a detector that monitors changes in excitation light intensity. Temperature sensors allow for signal corrections based on temperature variations of the detectors and sample.

Abstract: Provided herein are assay cuvettes as well as related kits and methods for storing and transporting multiple solid reagents, and for performing diagnostic assays using the reagents held therein. The solid reagents are constrained within separate containers inside a lid of the cuvette. The containers are open to the inner chamber of the cuvette such that, when liquid buffer, reagent, or sample solutions is added to the cuvette, the solid reagents can be dissolved in the liquid to create within the cuvette a mixture that can then be assayed.

Abstract: A generator is configured to generate electrical power from a natural fluid flow, such as wind. The generator has interacting devices for interacting with the fluid flow to generate relative rotation between a first mechanical member (301) and a coaxial second mechanical member (303). The first mechanical member has a plurality of permanent magnets (301) attached thereto so as to define a plurality of magnetic poles. The magnetic poles generate a radial magnetic field that also extends towards the coaxial second member (303). The second member includes a plurality of radially extending teeth (304) that define open slots (305) therebetween. A respective pre-formed coil (306) is located over each alternate tooth such that a single coil winding occupies each of said slots and said coil windings generate an electromotive force during the relative rotation.

Abstract: The present invention relates to a kit for taking biopsies, resections, excisions, and/or autopsies. Moreover, the present invention relates to methods of taking biopsies resections, excisions, and/or autopsies using the kit of the present invention. The kits and methods of the present invention allow for fewer errors, decreased turn around time and/or more rapid processing due to a cassette and specimen numbering system that is simplified and superior over that which has been previously disclosed in the prior art. The kit of the present invention comprises one or more tissue cassettes, and optionally one or more bottles of formalin and optionally, other components.

Abstract: There is provided apparatus for the measurement of particle mass concentration of an aerosol and which comprises at least one aerosol inlet and at least one electrostatic precipitator which directs an aerosol flow towards a mass sensor on which the particles are collected, said sensor being housed in a magazine including a plurality of other sensors, each of which may be substituted for said sensor, and a control. The control selectively connects one of said at least one aerosol inlet with one of the sensors.

Abstract: An apparatus and method for the analysis of particles in an aerosol includes providing an inlet for the aerosol, a sample collector which accumulates particles passing through the inlet, a sample conditioning system which can vary at least one condition relating to the collected sample, a controller which causes the sample conditioning system to operate at select conditions, a measuring device for determining at least one parameter relating to the accumulated particles. The controller monitors the parameter while the condition is varied.

Abstract: A universal microplate analyzer capable of carrying out measurements on samples contained in the wells of microplates by fluorescence, absorbance, luminescence employs at least two light sources and optical fiber channels for directing excitation light to the sample wells. Flexibility of operation is provided by arrays of mirrors, apertures, and polarizers which can be positioned as required for the analysis to be carried out.
