Innovative suspension system for magnetic stirrer follower bars which solves problems associated with mechanical abrasion of materials against the base of the vessel by the spinning bar, particularly in biochemical or tissue culture applications. Comprises 250 x 15mm L x diameter PVDF rod with U-shaped stirrer bar clip fixed to a rotating hub at one end. In use the rod is fixed at the neck of the flask using accessory stoppers, compression screw fittings or a retort clamp so that the bar is suspended at a suitable height above the flask base. Maximum operating temperature 160°C, and autoclavable. With clip size for 8mm diameter cylindrical bars up to 50mm long.
