Omrøremagneter

Magnetiske omrøringsstænger giver effektiv omrøring af prøver via magnetisk manipulation. Mange modeller har en ottekantet form med en central integreret drejering for optimal turbulens under omrøring takket være større overfladeareal. De er ofte belagt med teflon for at give kemisk inaktivitet; lejlighedsvis vil glas være belægningen til brug med de fleste flydende alkalimetaller og alkalimetalløsninger i ammoniak. Begge disse belægninger er inerte og vil ikke forurene eller reagere med reaktionsopløsningen.

Magnetstave, Komet

Supplier: THERMO H + P LABORTECHNIK

Komet magnetiske omrørerstave fremstillet af SmCo (samarium kobolt) har en PTFE-belægning, der gør det muligt at sterilisere stavene. Anbefales især til omrøring ved høj hastighed, væsker med høj viskositet og omrøring i kar, hvor der er stor afstand mellem omrører og omrøringsstav, for eksempel målecylindere.
