Abstract
The invention relates to a vessel and to a rod used with the vessel for collecting magnetic particles from a liquid containing the particles in the vessel, or for releasing the particles into a liquid in the vessel. The minimum distance from the rod, when inserted into the vessel, from the inner wall surface of the vessel is great enough at each point to resist or prevent any liquid ring or ring part from being formed between the vessel and the rod, which ring could be removed along with the rod. In this manner, liquid is prevented from being removed from the vessel along with the rod.
