The rotor of the second centrifuge could not turn anymore because it was corroded from the salt and water. Also, the resistor had apparently been soaked (it is located immediately below the cooling grill on the top back of the fuge).The centrifuge works again including the cooling. I do not know for how long we will enjoy it, because it was already 2nd hand when we bought it in 2014. But even if it lasts only for another year, the repair was worth it.This type of repair might become easier in the future because if I am not mistaken, the EU is planning to mandate that manufacturers make service and repair manuals available to third party repair shops (this mandate exists already for car manufacturers to ensure that independent car repair shops can survivce).Depending on the coronavirus, I will perhaps get around repairing even more broken lab equipment. Next in the queue is the fraction collector of our old FPLC (GE Healthcare Äkta Explorer Frac-950).
