Stuck dessicator lid

Post by megan28 » Tue Aug 03, 2010 1:26 am

I am trying to get into our dessicator to retrieve a sample but the lid is stuck badly. I don't think its been open for years! Any hints for how to get it open?

Force, patience and anger... I sympathize. Probably heating the sides where the 2 parts meet might help make the grease a bit more fluid and help sliding the thing apart, but I am not sure if it will work.
Having had a fight a few years ago with a nasty dessicator (two people were needed for convincing, and we were thinking of using a hammer at that point) I would be interested if anyone had a foolproof way to deal with those... Good luck

I have used a heat gun and a lot of patience. After 10-15 minutes, the lid slides right off.

You might try dripping a bit of machine oil into the seam so it can penetrate the grease. Having some shorter hydrocarbons diffused into the grease should loosen its grip. Let it penetrate for a few hours, the diffusion likely won't be fast though the grease. Hexane would be a reasonable alternative to machine oil.
