Stand<br />
Used with the electric burner (> 666 776)<br />
when heating larger vessels.<br />

Electric burner<br />
Heating mantles for round-bottom flasks<br />
Used to heat cylinders, beakers,dishes,<br />
crucibles, dry and melt, all without an open<br />
flame. The draft tuble is made of a ceramic<br />
material which is resistant to heat, acids and<br />
bases.<br />
The coils inside serve as heat exchangers for<br />
the heating elements, which are therefore not<br />
charged. The fully enclosed design of the<br />
heating eliminates problems if liquids should<br />
splash or overflow.<br />
Complete with power cord and plug.<br />
For setting and keeping the intermediate<br />
temperatures we recommend our power<br />
cntroller (> 667 823).<br />
