A filter is used for removing metallic contaminants in a solvent used in microcircuit fabrication. The filter includes a filter housing including a filter membrane for filtering solvent including metallic contaminants, and a magnet arranged about the filter housing and configured to generate a magnetic field to attract the metallic contaminants prior to the metallic contaminants entering the filter membrane. The magnet is arranged such that the magnetic field of the magnet is greater in a periphery of the filter housing compared to a central portion of the filter housing.

The present invention relates to a magnet plate for use in isolating a macromolecule from a mixture in a vessel, wherein the magnet plate has a reversible compression lock. The reversible compression lock engages the top plate and the base plate, wherein when in a locked position, the top plate is fixed and cannot move up and down, along the axis of the support or corner post and when in an unlocked position, the top plate is movable up and down along the axis of the support.

An integrated nucleic acid processing apparatus includes a first operation area, a second operation area and a separation wall. The first operation area includes multiple carrying boards for placing objects and reagents for processing nucleic acids in samples, and multiple operation modules for performing operations of nucleic acid processing. The second operation area includes two extraction regions for respectively performing nucleic acid extractions. The separation wall separates the first operation area from the second operation area and includes two openable door sheets spatially corresponding to the two extraction regions. Nucleic acid extraction plates can be moved from the first operation area to the second operation area by means of the carrying boards as the two openable door sheets are opened, and be isolated in the second operation area for performing nucleic acid extractions as the two openable door sheets are closed.

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 manufacturing method of an operation pipe, which use a gel to perform operations such as separation, extraction, purification, elution, recovery, analysis and the like of target components that are biological components such as nucleic acids. More specifically, a manufacturing method of an operation pipe, with which it is possible to perform operations such as separation, extraction, purification, elution, recovery, analysis and the like of target components in a sealable pipe by operating magnetic particles in the pipe under a magnetic field from outside of the pipe.

A hydronic system separator has an air separator with a vent release mechanism to remove air from the fluid within a hydronic system. The separator includes a magnetic assembly for collecting ferrous particles from the fluid. One or more screens are used to remove other particles from the fluid. The separator housing includes a removable debris collection receptacle that has a drain assembly.

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.
