Copper evaporation rate?

so is copper safe to use? or would i have to get new drop tubes every year cause of corosion?is the green oxidation safe to have sap in contact with?

The copper drop tubes, made of copper water pipe or water hammer arrestors, is easy to clean and strong enough to survive rough handling. I used them for years with no corrosion problems, no off colors or tastes. The fellow I gave them too is still happy to be using them with similar good results. Don't panic. Fresh sap and sweet does not seem to be acidic enough to cause a problem of corrosion.

well thats good to hear. drop tubes it is...for next year.

We need to assist in filling out the survey. The research done by UVM Proctor Research directly benefits what we love to do.


Thanks to those who have completed the survey so far....but we need a LOT more participation. Please complete the survey at

People want to make light syrup and a reverse osmosis will get rid of the extra water for the price of a brand new copper evaporator. they do have used ones. Stainless is definently the way to go.

The thing is that I have the money for drop tubes but not enough for an RO. I think will just make a stainless flue pan. And then maybe get an RO eventually.
