Introduction Page 4 The TMR magnetic stirrer was developed for the pharmaceutical industry and biotechnology to thoroughly mix sensitive products in a sterile and gentle way, and to make the FDA and GMP-conform documentation of the stirring process possible. Further applications can be found increasingly in industrial branches where sterile or toxic liquids are stirred e.g. in glass vessels. For this purpose, the devices have been designed without compromise for permanent use in the production process and work maintenance-free for years even under difficult environmental conditions. The integrated fault indicating system for the stirring staff combines the advantage of the magnetic drive with the safety of a mechanically coupled stirring unit: ••• Sterility, since no shafts are routed through the product space. ••• Universal use of a wide range of different container types made of non-magnetic materials, such as various stainless steels, plastics or glass. ••• Easy cleaning and sterilising of the stirrer staff, no complicated storage geometry as with impeller stirring units. CIP and SIP-friendly design. Sterile containers can be sterilised with stirring staff in the autoclave. ••• One magnetic stirring system can be used for several batching tanks, since the drive unit is not connected to the container. With mobile containers, for example, batching can be carried out in a different production area. ••• Powerful and centring magnetic drive field, so that distances of a few centimetres between the stirring unit and the magnetic staff can be realised. ••• Fault message when the magnetic force closure between drive and stirring staff breaks down, which can happen with magnetic stirrers on account of the system and leads to uncontrolled standstill of the stirring function despite rotating stirring unit. "Automatic stirring staff catch" for the automatic reestablishment of the stirring function. ••• Time sequence control for the linear speed reduction at filling stations for e.g. vaccines containing adjuvants in order to avoid foam forming when the filling level in the product container drops. ••• Clear documentation of the stirring process according to FDA and GMP guidelines through recording of speed curves and fault message voltage by means of a recorder.

Function Page 5 TMR magnetic stirrers produce a 2-pole permanently magnetic rotating field with a diameter of 100 mm (TMR-102-...) respectively 200 mm (TMR-202-...) . The magnetic field lines are bundled by special pole shoes and project almost vertically from the work surface. There is a magnetic staff in the product container that aligns itself in the drive field on account of the magnetic attractive force and is rotated synchronously by this field. This allows stirring unit and magnetic staff to rotate at the same speed in uninterrupted operation. In contrast to the directly driven stirring unit, however, the forced closure between the drive and stirring staff can break off with the magnetic stirrer, so that the stirring process is interrupted despite the fact that the stirring unit is still rotating and thus producing a speed indication . This operational problem cannot be detected without visual inspection and requires the use of supervisory personnel as well as containers with optical control possibilities. Since the stirring staff cannot synchronise itself automatically after a break in connection, the stirring process remains interrupted until the speed has been reduced manually. In sensitive areas of chemical-pharmaceutical laboratory and production technology, automatic
