Hello All-

I was hoping that someone on this e-mail list may have some answers to a few questions regarding a mercury diffusion pump.

We would like to remove the mercury from the diffusion pump. Once the mercury is removed we would like to dispose of the remaining glass diffusion pump properly, I am wondering if anyone has any experience or has attempted to do this previously that we could learn from.

Questions are:

What is the easiest way to remove the mercury from the diffusion pump?

Are there vendors who deal with disposing of mercury contaminated glass?

I appreciate any insight or help that can be provided. Thanks. I do have photos of the pump but they can't be sent to this list serve. So if seeing these would help you please email me directly and I can send them your way. Thanks again for your help in advance?

Regards,

I respectfully acknowledge that Willamette University was built on the land of the Kalapuya, who today are represented by the Confederated Tribes of the Grand Ronde and the Confederated Tribes of the Siletz Indians, whose relationship with this land continues to this day. I am grateful to the land itself, to those who have stewarded it for generations, and for the opportunity to study, learn, work, and be in community on this land. I acknowledge that the University's history, like many others, is fundamentally tied to the first colonial developments in the Willamette Valley. I respectfully acknowledge and honor past, present, and future Indigenous students of Willamette.
