Sorbent-coated disc consisting of a polytetrafluoroethylene (PTFE) base with an integrated magnet and a sorbent film attached to one side.

Note: Facilitates more rapid stirring than conventional sorbent-coated stir bars (see stir bar sorptive extraction) without deterioration of the sorbent coating, because it is not in contact with the vessel wall.
