A magnetic mixing device designed to mix fluid in a reaction chamber and remove air bubbles if present. The device comprises a holder with embedded magnets, which causes movement of a stir bar within the reaction chamber. The holder may be moved by an electric linear actuator configured to generate linear motion or an electric motor configured to generate a circular motion. When orientated so the stir bar moves vertically within the reaction chamber, the stir bar disrupts any air bubbles trapped within or below the fluid.

Device and method for mixing and bubble removal

A self-metering reaction device has a sample reservoir, configured to accept a varying amount of fluid; a metering reservoir, configured to be a subportion of the sample reservoir and to hold a reaction amount of the fluid; a reaction chamber fluidly connected to the metering reservoir; and a plunger comprising a tip configured to make a seal with the metering reservoir so that the reaction amount of the fluid is sealed within the metering reservoir when the plunger is in contact with the metering reservoir. The plunger can be configured to plunge the sealed reaction amount of the fluid from the metering reservoir into the reaction chamber.

A robe garment provided with an integrated mammary support incorporates support system is provided. The robe may be operable to envelop a torso and features a front and a strategically positioned posterior opening. The support system includes bilateral mammary cups, each tethered to a respective cable. These cables are conjoined to belts emanating from the robe's posterior opening and the actuation of these belts facilitates breast elevation, thereby providing tailored support. Additionally, the robe is equipped with interior guide loops for precise cable navigation, exterior belt loops for belt alignment, and a concealing rear cover to enhance aesthetics and ensure user privacy.

A collection device is disclosed having a tubular housing detachably receiving a valved bulb reservoir at a first end thereof, the housing having a second end for dispensing fluids. The valved bulb reservoir has a sample capillary tube attached at one end thereof. The bore of the capillary is fluidically coupled to the valved bulb reservoir. The capillary is removed from the tubular housing to collect a sample in its bore, and is then replaced into the tubular housing. The contents of the valved tubular reservoir, which can be a buffer solution, a reagent, or other analytic fluid, or a gas, are then passed through the capillary bore to expel the sample and mix therewith in the housing. The sample product can then be dispensed from the tubular housing.

Embodiments of present disclosure are directed to methods for amplifying nucleic acid, comprising two steps: a first step of preparing a reaction mixture comprising the target nucleic acid and a second step of processing the reaction mixture in a thermocycler. During a first phase of the processing step, the thermocycler may be configured to heat the reaction mixture to a first temperature and cool the reaction mixture to a second temperature repeatedly for a first plurality of cycles. During the first phase, fluorescence probes do not anneal to template strands and do not emit fluorescence signals. During a second phase of the processing step, the thermocycler may heat the reaction mixture to a third temperature and cool the reaction mixture to a fourth temperature repeatedly for a second plurality of cycles. During the second phase, fluorescence probes anneal to the template strands and are degraded by DNA polymerase to emit fluorescence signals for detection and/or quantification of the target nucleic acid. Methods for amplifying nucleic acid in accordance with the disclosure may be employed for nucleic acid amplification and detection in clinical and research settings.

Methods for temperature-mediated nested polymerase chain reaction

A method and system for solid phase extraction of a compound of interest from a sample matrix using a syringe having a barrel and a plunger, a sorbent for use with the syringe, and a desalting purification column having an end configured to receive liquid from the syringe body.

The invention relates to aspore specific antigen. Compositions and methods relating to the antigen are provided along with antibodies against the antigen. The antigen is specific forspores relative to the vegetative form of the cells. The antigen is detectable on ungerminated spores. The antibodies may be used to detect the presence ofspores by use of methods provided herein. The invention also relates to articles of manufacture as well as kits comprising the antibodies which may be used in the detection methods of the invention.

Spore specific antigen

Weight belt apparatus for divers includes a belt with one or more sleeves disposed on the belt and adjustable thereon for the convenience of the diver using the apparatus. Each sleeve includes one or more pouches for receiving and holding weights. The pouches are collapsible for convenience when no weight is disposed therein.
