A magnetic stirrer apparatus for culture medium and other liquids comprises a flask having a floating stirrer in it; a driving guide rod extends downwardly into the flask, and has a sliding drive connection with the floating stirrer. The driving guide rod is suspended from a bearing on the underside of the flask closure, and carries a driven magnet, which is magnetically coupled with a motor-driven magnet on the outside of the closure.
