All-

Thank you all for your advice and careful consideration of the best approach to deal with this issue. I appreciate everyone's comments. Based on what I have heard and since we do not plan to keep the pump, we will more than likely treat the whole unit as one hazardous waste disposal. One of the professors wanted to keep the mercury so they could use it in a demo to show density concepts. However, I have been trying to convince them that it is probably not the best way to go. We already have an amazing demo in house that demonstrates this better in my humble opinion.

Have a great rest of your week and thanks again.

Todd

A few years back, we had a mercury thermometer break inside a drying oven. Rather than deal with the headache of trying to disassemble and decontaminate the whole thing, we disposed of the entire oven as hazardous waste. I don=E2=80™t know if that was the most economical choice we could have made, but it was a straightforward solution that minimized risk of exposure and allowed us to quickly move forward.
