A magnetic stirrer wherein a relatively weakly magnetised disposable stirrer bar (14) inside a closed container (10), for example a stirrer bar moulded wholly of non-isotropic ferrite, is moved with a stirring action from outside the container by a relatively powerful magnetic driver (16), preferably consisting of a pair of permanent magnets (18, 20) of neodymium boron driven in rotation as an assembly. |
