A pipeline strainer having a body with a straining element therein. One or more magnets are removably inserted into the straining element and configured to be removed from the body without causing liquid within the cavity to drain from the pipeline strainer. A drywell is used to house the magnets. The movement of withdrawing the magnets pulls metal particles along the outer surface of the drywell toward a debris drain. A baffle is disposed at the end of the drywell that is adjacent or near the debris drain to reduce turbulence from the fluid flow within the pipeline strainer.

The present invention relates to novel modules for transferring magnetic beads, an automated system comprising the same and a method for extracting nucleic acids using the same. The specifically designed magnet module and cover module of the present invention can be employed in the automated liquid handling apparatus by means of pre-existing moving modules (e.g., pipettor module) of the apparatus. The present invention enables a bead transfer-type method for extracting nucleic acids to be performed in an automated manner on the automated liquid handling apparatus. The present invention provides advantages of higher level of automation, more reduced cost and no need for another separate liquid handling apparatus compared to the conventional bead transfer-type method usually performed in the small apparatus designed to be used only for this bead transfer-type method. Also, the present method has the merits of more shortened reaction time compared to the conventional liquid transfer-type method.

A classifying and purifying apparatus of a solid blowing agent includes a classifier which classifies a supplied solid blowing agent into first microspheres and second microspheres, a storage connected to the classifier, in which the classified first microspheres flow in to be stored and emitted, and a filter arranged on the moving route of the solid blowing agent or the first microspheres which separates metallic substance from the object of filtering comprising the solid blowing agent or the first microspheres.

A switchable magnetic filter for collecting metallic particles in a fluid flowing through a vessel, comprising a handle for rotatably or slidingly engaging a magnetic assembly within a housing to an ON position to create a magnetic field outside of the housing to collect and retain metallic particles against the outer wall of the housing, and to an OFF position to shunt the magnetic field within the housing to release the metallic particles from the outer wall of the housing so they may be removed from the fluid for cleaning purposes.

The objective of the present disclosure is to provide a technique for reducing a quantity of magnetic particles remaining on a reaction vessel wall surface in a cleaning step for reducing, in a stepwise manner, an amount of a magnetic particle solution in the reaction vessel. The automated analysis device according to the present disclosure causes an agitating mechanism to operate in such a way that a magnetic substance remaining on the wall surface of the vessel in the previous cleaning step is captured by a cleaning solution in the next cleaning step.

A purpose of the present invention is to suppress reduction in recovery rate of a target component due to a gel adhering to an inner wall surface of a treatment liquid layer. After passing magnetic particles through a gel layer, when moving the magnetic particles in the treatment liquid layer adjacent to the gel layer, the magnetic force source is automatically operated in a longitudinal direction of a tubular container so that the magnetic particles do not enter a range of a certain distance from the gel layer through which the magnetic particles have passed.

A temperature-controlled tramp metal separation assembly includes a core rod and a magnetic set. The core rod is made of non-magnetic materials and includes a chamber, a first end with an air inlet, and a second end with an air outlet. The magnetic set includes a plurality of magnetic members and a plurality of spacers respectively disposed between the two adjacent magnetic members. The magnetic set is nested in the chamber in a way that an air path is formed therein so that an external cooling air flow can be introduced from the air inlet, and then discharged from the air outlet via the air path. Thus, the operating temperature of the tramp metal separating process can be maintained at an acceptable level, preventing the magnetic force of the magnet set from being reduced.
