FIELD: devices for magnetic particles collection and removal from a liquid in a vessel or their separation and transportation into a liquid in a vessel.
SUBSTANCE: the invention is pertaining to a vessel and a rod applied together with it and is intended for collection of magnetic particles from a liquid containing the particles in the vessel, or for separation of the particles and their transportation into a liquid in the vessel. The invention ensures elimination of possibility of excision of a liquid from the vessel together with the rod. The complete set contains a vessel and an applied together with it rod supplied with a magnet used for collection of magnetic particles from the liquid containing the particles in the vessel, or for separation of the particles present in the liquid in the vessel at the rod insertion in the vessel and taking the rod out of the vessel after a collecting or separating operations. The rod has a narrowing end section, on which the indicated particles are gathered or from which they are separated. The space interval from the rod inserted into the vessel up to the vessel internal wall is taken in each point sufficiently big to avoid a formation between the vessel and the rod of any liquid ring or a part of the ring, which could be removed together with the rod at taking the rod out of the vessel. The vessel has a bottom with a pit for the rod insertion. At that the pit profile matches to the profile of the rod narrowing end section.
EFFECT: the invention ensures collection of magnetic particles from a liquid onto the rod in the vessel or their separation and transfer into a liquid in the vessel eliminating possibility of excision of a liquid from the vessel together with the rod.
