Debbie, Several years ago we had to decommission 12 labs under the care of a retiring German organo metallic synthetic researcher. The faculty and staff were proactive and worked with us for over a year to safely shut down 30 plus years of stuff created by this research group. They had several large (4 L) NaK stills. We found a well written procedure for sodium drying stills taken from the University of Guelph's website We peer reviewed the procedure with in house organo metal faculty modified to fit NaK. I can send the procedure directly if your interested. We did modify these procedures as we developed some expertise with Nak. I can also add some observations that were just part of the learning process. It can be done safely with some precautions. Feel free to contact me for any of this information.
