A target substance is collected from a composition by using magnetically responsive particles and a magnetic transfer probe. The composition may be prepared, e.g., by introducing magnetically responsive particles to a sample. The particles selectively bind to a target substance of the composition. The target substance and the particles are collected from the sample by using the magnetic transfer probe, which comprises a probe magnet. The probe magnet is a permanent magnet, which comprises a cylindrical portion and a convex bottom portion adjoining the cylindrical portion. The particle collection region of the magnetic transfer probe is at a low position, which allows collecting the particles from a small amount of the prepared composition.

Embodiments of the invention relate to a clinical instrument analyzer system for the automatic analysis of patient samples. In one embodiment, the analyzer may be used to analyze bodily fluid samples, such as blood, plasma, serum, urine or cerebrospinal fluid, for example. Embodiments of the invention relate to an apparatus and method, for example, an immunoassay method, for separating out target molecules in a magnetic field and then analyzing those target molecules with a luminometer.

A method for performing a magnetic separation procedure that includes transporting a receptacle containing a fluid medium to a first location of a system, where the fluid medium contains both a sample material and a suspension of magnetically-responsive solid supports. At the first location, the fluid medium is exposed to a first magnetic field for a first dwell period, thereby isolating the solid supports within the receptacle, where no portion of the fluid medium is removed from the receptacle at the first location. The receptacle is then transported from the first location to a second location of the system, where the fluid medium is exposed to a second magnetic field for a second dwell period. Following the second dwell period, at least a portion of the fluid medium is removed from the receptacle. A suspension fluid is then dispensed into the receptacle, and the contents of the receptacle are agitated to suspend the solid supports within the suspension fluid.

A magnetic rod guide for a filter comprises a base for attachment to part of a filter, a through aperture through which a magnetic rod can move, and resilient engagement means including at least one resilient latch for holding the magnetic rod in one or more fixed positions relative to the guide, the or each resilient latch further being adapted to allow movement of a magnetic rod through the through aperture in either direction, for insertion into the filter or withdrawal from the filter into one of the fixed positions.

A magnetic filter for a central heating system is disclosed, the filter including a separation chamber, a magnet for capturing magnetic particles within the separation chamber, an inlet for fluidly connecting to a central heating system circuit, an outlet for fluidly connecting to a central heating system circuit, and a single valve operable to select between at least two positions, the valve in a first position fluidly connecting the inlet to the separation chamber and fluidly connecting the outlet to the separation chamber and the valve in a second position isolating both the inlet and the outlet from the separation chamber.

The invention relates to a method for the chip-removing production or machining of a workpiece by means of a tool, in which method a liquid, which mixes and accumulates with the chips produced during the machining process, is used for lubricating and/or cooling the machining process, and the chips are discharged from the accumulation counter to the downhill force along a discharge path by means of a magnetic force, wherein a return flow of the liquid carried by the discharged chips occurs due to the downhill force, and the return flow is deflected out of the discharge path and/or the discharge path has at least one point at which the supporting surface is temporarily withdrawn from the discharged chips.

The present disclosure describes a filtration device that includes a housing that includes a first tubular section connected to a second tubular section, wherein the first tubular section extends along a longitudinal axis and includes an open end that forms a fluid inlet of the housing, a closed end opposite the open end, and a connection opening positioned between the open and closed ends, and wherein the second tubular section includes a first open end connected to the connection opening of the first tubular section and a second open end that forms a fluid outlet of the housing; and a filter that is arranged inside of the first tubular section and that extends along the longitudinal axis of the first tubular section; wherein the filter includes an electromagnet configured to generate a magnetic field that surrounds at least the first tubular section and attracts metal contaminants in a fluid to the filter. A filter system is also described.

A magnetite level monitoring device for a magnetic filter in a central heating system, the magnetic filter including a separation chamber, an inlet to the chamber and an outlet from the chamber, and a magnetic element disposed within the chamber for attracting magnetic particles and removing the magnetic particles from the system water as it flows through the chamber, and the monitoring device including: a housing for placing adjacent to the outside of the separation chamber; a magnetometer mounted to the housing; a magnetic field guide mounted to the housing, the magnetic field guide being disposed between the magnetometer and the outside of the separation chamber, when the housing is mounted to the separation chamber; and output means adapted to issue a notification when the output from the magnetometer exceeds a predetermined threshold.
