[Q]: How can I remove this stopper from the distiller ?


I have been using this distiller for years. It works great, particularly with the water cooling.
But I cannot use a thermometer in the top with the NS 14.5/23 plug, because I cannot remove the stopper. I am reluctant to use brute force, because the distiller will probably break.

Does anybody have ideas how to remove it ?

I would remove it by rigorous application of the search engine on this site.

Wedge the search engine between the stopper and the neck of your glassware, and then enter an appropriate term in the search engine to get advice.

You may want to lubricate the search engine to some extent with WD-40 or other light penetrating oils, or even heat the search engine with a torch so it will expand slightly, loosening it if it's stuck.

Some people boil their search engines in carbonated water and this can work for smaller stuck parts according to the instruction sheet that comes with some microscale glassware kits.




They always say, "He lost his battle with cancer." But as Norm MacDonald pointed out, the cancer dies at pretty much the same time you do, so doesn't that make it a tie?

Try heat (submerge in warm water to heat up the outer joint) and the wooden dowel method. Or maybe an acetone soak could help penetrate the joint.

I tried each one of those methods and they all worked for me, but the best method was the hot water method suggested by monolithic. it has unstuck a couple stoppers for me. Then I started using lithium grease.

You can as well take a spoon and knock the plug around, using some force, but not too much, not to break the stopper. You can heat it before doing so. Sometimes it works.

Allow time. It is easy to get impatient.
I had a sep funnel recently with a similar issue. I can't remember which solution finally worked but I do remember that leaving it for >24 hours soaking in something certainly helped.

I had the same issue recently. It felt as if the the stopper and the joint became one. I passed the joint through warm water while applying my Grip Strengthâ„¢ to it for like 20 minutes hard enough that it felt it was gonna break. It eventually came off after a while but the stopper was only the the joint for like five months instead of years in your case. You could try to let solvent through the cracks such as acetone or alcohols like methanol, ethanol, or isopropanol. Well, good luck and try not to break it when forcing it off :D.

Even in the depths of despair a SWIM post has the ability to make me smile (and generally I also learn something as well!) - Thank you:)

I learned the hard way not to ever leave any glass joints coupled. Broke a couple.

I have a very nice rotovap multi port condensor with a plug stuck as well and I'm at a total loss as to how to get it out. If you (OP) finds something that works, let us know!
