Cork/stopper

[Biff_McNielly]

Can I use a natural cork (like a wine cork) for my temperature probe? Or can someone recommend a safe stopper to use? I believe rubber and plastics are a no no…

Natural cork yes, BUT most wine corks are composite or agglomerated cork. use those words to search here on HD

There are at least three other industries that use the term natural to describe their products when in fact their

products are agglomerated cork, or composite cork. Widget co has real natural cork along with other forms of cork.

Your local hardware store may have natural cork. Search here on HD and learn the difference it's easy and readily

apparent visually, then decide if what you have is suitable.

How are you mounting your thermometer?

I have a little bit of brake line i soldered into place that the stainless probe of my thermometer fits quite nicely into, so all it needs is a couple of wraps of ptfe tape to seal.

Obviously this wouldnt work as well with just a hole in the wall of a copper pipe.

Biff,

Just curious. What/where is the thermometer going to be used for? What are you monitoring, what kind of still/rig/column?

Lots of members on here use natural cork as a thermometer port. Just make sure the hole is slightly smaller than the temp probe and you'll be good to go!

The thermometer is going smack in the center of the top of my column.
I don’t know exactly what to call this column other than an experiment at this point. It’s built out of spare parts, scrap pipe I had on hand, and random ideas that were all thrown together honestly. It’s really just something to occupy my time and just see what works. But I want to get an accurate temperature reading of the distillate as it enters the lyne arm. The kettle has a thermometer on it so I figure between the 2 I can get a good idea of what’s going on in there

Understood. Well it at least sounds like you are having a grand time with the creativity of it. Enjoy

He has another topic where he posted a pic of the still. He's using the thermometer above a dephlegmator near the vapor takeoff.
