Analytical assay reaction cartridges, kits containing same, and methods of production and use thereof are disclosed. These cartridges include a magnetic assembly that surrounds at least a portion of a sample read window on the cartridge. The cartridge also includes an analytical reagent positioned therewithin, wherein the analytical reagent comprises magnetic beads coated with at least one anti-red blood cell antibody.

The present invention is directed to a method for sorting biological objects including the steps of providing a magnetic device that includes a conduit or channel having upstream and downstream sections and a magnetic means for generating first and second magnetic fields in the upstream and downstream sections, respectively; flowing a sample fluid that includes magnetically labeled biological objects and unlabeled biological objects through the upstream section to magnetically saturate the magnetically labeled biological objects by the first magnetic field; and flowing the sample fluid from the upstream section continuously to the downstream section to collect the magnetically labeled biological objects on a wall of the downstream section by the second magnetic field, wherein the first magnetic field in the upstream section has a higher average field strength than the second magnetic field in the downstream section.

Apparatus is providing featuring a synthetic bead having a solid-phase body with a surface, and being configured with a predetermined electric charge so as to respond to a corresponding predetermined electric field; and a plurality of molecules attached to at least part of the surface, the molecules comprising a functional group selected for attracting and attaching one or more mineral particles of interest to the molecules. Some combination of the solid-phase body or the surface may be configured from a polymer. The polymer may be polyethylenimine. The polyethylenimine may be engineered or configured to be highly charged so as to be used to collect the mineral particles of interest and then manipulated through and by the corresponding predetermined electric field.

The present invention relates to recycling tires and the like utilizing a microwave service controlling the pressure from such a process enables a more even temperature and helps prevent the buildup of explosive gas.

A belt system for a water treatment system comprising a flocculation tank. The flocculation tank is configured for receiving wastewater having one or more of unwanted waste solids, unwanted particulates, suspended solids via the ingress and for mixing the wastewater with a flocculating agent and magnetite within the flocculation tank. The belt system comprises a looped belt comprising a plurality of rare earth magnets. The first looped belt is mounted within an extraction portion of the flocculation tank. A first portion of the first looped belt is above a water level inside the flocculation tank. A second portion of the first looped belt is submerged in the flocculation tank. A first scraper is positioned proximate to the first looped belt that is above the water level. A container is below the first scraper and the first looped belt and above the water level. An auger is within the container.
