2.5 Combinations of vessels Please use round, heat resistant vessels made of glass or non-magnetic metal. You can use vessels up to the maximum size stated in the spread sheet 1. The vessels should have a thin, even wall thickness. Flat glass bottoms (without any curve to the inside) and smooth surfaces will improve the operating characteristic of the magnetic stirring bar. At the same time they will improve the heat transfer from the STIRRING HOTPLATE resp. the STIRRING DRYBATH to the liquid. Uneven surfaces would reduce the stirring power and would cause reaming up of the stirring bar’s gliding surface. In case you intend to stir large amount of liquids, please chose such stirring flasks that have a comparatively small diameter and thin bottom. The magnetic stirring bar can then be centred better.

Version: 5.1
Do never use any pressure-tight closed flasks. RISK OF BURSTING!
Use only temperature-resistant vessels. Be careful with plastic flasks!
2.6 Stirring bars In general, all stirring bars matching the length and diameter can be used. But we recommend using the commercial stirring bars with Samarium Cobalt magnetic core (SmCo). By using this highly energetic magnetic material the maximum stirring power of the magnetic stirrer can be achieved, especially when mixing viscose media.
2.7 Tips and hints to the topic stirring The mixing flasks should be filled max. up to the middle (high speed range) resp. up to ¾ (low speed range). Place one magnetic stirring bar in each stirring flask. Place the stirring flasks right in the centre of the stirring point on the STIRRING HOTPLATE resp. in one borehole of the STIRRING DRYBATH. In case the magnetic stirring bar turns in an unsteady or jerky way or bounces: The interaction between the alternating magnetic field and the magnetic stirring bar is too high. Increase the speed or Use a smaller magnetic stirring bar or Decrease the stirring power. In case the magnetic stirring bar will not be centred or leaves the centre permanently: The interaction between the alternating magnetic field and the magnetic stirring bar is too low. Or the stirring bar has a bottom that is uneven or too thick-walled.

Version: 5.1
Move the flask slightly back and fro and centre it again onto the stirring point of the STIRRING HOTPLATE resp. in the borehole of the STIRRING DRYBATH. Reduce the speed or use a longer magnetic stirring bar or one with a larger diameter or Use a smaller flask with a thin-walled, even bottom or Reduce the filling amount in the flasks or Increase the stirring speed. In case the stirring activity is too weak: Use commercial magnetic stirring bars with SamariumCobalt-core. Use a longer stirring bar or a stirring flask with smaller diameter.

4.2 Heating operation and heating control Do not heat up liquids whose flashpoint is lower than the set temperature. Explosion hazard! Fire hazard! HOT Hotplate resp. HOT Drybath! Temperatures up to +200 °C possible! Burning hazard! With temperatures of above > +150 °C the PTFE coating of the Hotplate resp. of the Drybath will soften. In this actual condition, never place any hard or edged devices on the surface. Operation note: Interrelation of temperature controller and integrated adjustable over-temperature limiter The control unit 2mag heatMIXcontrol is equipped with an additional independent and adjustable over-temperature limiter. The over-temperature limiter is always of higher ranking, which means that in case of the actual value of the measured temperature being higher than the set limiting maximum value of the over-temperature limiter, the heating controller will be limited and as a result of this the heating is cut off. In case of the actual value being lower than the set limiting value of the over-temperature limiter, the heating controller will be activated again and the control process will be started again. The over-temperature limiter is an additional safety protection measure in case of potential heating controllers’ defects or other malfunctions. In addition, the maximum temperature of the heating block can be limited to protect temperature-sensitive samples against accidentally overheating. The over-temperature limiter works with a second own temperature sensor and is, therefore, technically absolutely independent of the heating controller.

Heater control The control unit heatMIXcontrol is equipped with a precise and modern heating controller. All necessary parameters were set factory-made, optimized to the corresponding heating system and locked against accidentally shift. Therefore, only the setting of the SET-temperature can be made. As a result, a fast and precise heating will be guaranteed without high overshooting when the target temperature is reached. 4.2.1 Adjustment – Heater SET-Temperature Please press 1x MODE-key (12) for selection of the configuration layer “SET temperature heater”. By pressing the MINUS-key (15) respectively the PLUS-key (16) just after pressing the MODE-key, the SET temperature can be adjusted between +30°C up to +200°C in steps by 1°C. The adjusted SET temperature is shown in the display (14, lower line), e.g. “S.200”. The display is showing the value in °C. The actual hotplate-/ block-temperature is shown in the standard display layer. The display (13/14) will turn back to the standard display layer after approx. 5 seconds. The temperature adjustment is finished then. The SET temperature adjustment can also be finished immediately by pressing 6x the MODE-key (12) again return to standard display layer. The heating process is immediately starting after setting the SETtemperature. Operation hint: The available adjustment range of the SET-temperature is limited by the adjustment of the over-temperature limiter. Example: The set maximum temperature of the over-temperature limiter is +150°C. In this case it is not possible to adjust higher SETtemperatures than +150°C at the heater controller.

The adjusted MAXIMUM temperature is shown in the display (14, lower line), e.g. “L.200”. The display is showing the value in °C. The actual hotplate-/ block-temperature is shown in the standard display layer. The display (13/14) will turn back to the standard display layer after approx. 5 seconds. The temperature adjustment is finished then. The SET temperature adjustment can also be finished immediately by pressing 5x the MODE-key (12) again return to standard display layer. Operation hint: The adjusted MAXIMUM temperature is the maximum SET temperature of the heater controller, too. 4.2.3 Switching – Internal/External Temperature Sensor Please press 3x MODE-key (12) for selection of the configuration layer “Switching – Internal/External Temperature Sensor”. By pressing the MINUS-key (15) respectively the PLUS-key (16) just after pressing the MODE-key, the internal or alternatively the external sensor for controlling the probe temperature can be activated. The adjusted status is shown in the display (14, lower line) with. “_. I” for INTERNAL or “_. E” for EXTERNAL. The display (13/14) will turn back to the standard display layer after approx. 5 seconds. The adjustment is finished then. The sensor adjustment can also be finished immediately by pressing 4x the MODE-key (12) again return to standard display layer. The temperature control process after switching to the external temperature sensor is working only with the external sensor. The internal temperature sensor is switched off then. The adjustment of the SET-temperature is working as explained in “4.2.1 Adjustment - Heater SET-Temperature”. The over-temperature limiter is active during using the external temperature sensor, too.
