Page 14: Stirring Vessels
We recommend using PTFE coated magnetic stirring bars supplied by THERMO SCIENTIFIC. The bars are made from AlNiCo5 magnets or high performance rare-earth permanent magnets. The following sizes are suitable: Thermo Scientific recommends the following magnetic stirring bars: Type Size (mm) Material Order No. - Page 15 4 Startup procedure Thermo Scientific has developed a new magnetic stirring bar KOMET (Figure 6). It contains a high-quality super-strong samarium-cobalt magnet. KOMET shows a strong magnetic force. The stronger attraction to the magnetic alternating field provides the stirring bar with very efficient stirring properties. Even if there are greater distances (e.g.

The rotation speed is reduced at the end of every stirring period, and the stirring is stopped. After every pause the stirrer is restarted. The direction of rotation is reversed, the magnetic stirring bars are recentered and the rotation speed is slowly increased again. 50108226_02.2007 Thermo Scientific... -
Page 22: Selecting The Startup Time
Increase the stirring power of the TELEMODUL 20 C / 40 C. If the stirring action is too weak: Use the magnetic stirring bar KOMET. Use a longer magnetic stirring bar or one with a larger diameter, or a stirring vessel of smaller diameter.
