Hagar681,
I can't answer your question. However, I have a Anton Paar DMA 35 for sale. I picked it up after the ADI conference since they had a special pricing for ADI. I have since abandoned my distillery plans and I have no use for it. I only used it a couple of times to dilute NGS with distilled water, so it is as clean as new.
Let me know if you are interested.
Tom
