<p class="MsoNormal"><span style="font-family:"Garamond",serif">I have a silly question: what type of water do people use to keep the microscopes happy and chilled? We have already had two instances of corrosion on the cameras (K3), which have resulted in uber-pricey
repairs, but the other parts of the microscopes seem perfectly fine and corrosion-free. The water does not show any unusual hardness or presence of ions that could be blamed for the corrosion. I am very interested to hear if other people have faced similar
problems, and how they have been solved.<o:p></o:p></span></p>
