Anyone make a reasonably priced GL45 to glass joint adapter? The ones I’m seeing online are 100+ dollars for a freaking plastic bottle cap.

Honestly if I can’t find any cheap ones I would rather send money to you then buy this one online.

I’ve been kind of lucky scouring eBay for cheap adapters like this but no luck on this one

turns the cap of your media storage bottle into a 24/40 glass connection. I want to use it to vacuum filter with my buchner what goes into the bottle.

Watch out for large flat bottom bottles under vac, they tend to implode.

If you can get me a good detail drawing for the gl-45 side I can make a cad file and have one quoted in ptfe or acetal

P.S. For the Tri-Clamp female joint, make sure to select the 1.5" Tri-Clamp x 24/40 Female option (on the product page in ShopBVV, the images of the 1.5" and 2" seem to be swapped by mistake, if you zoom in you can see the image on the 2" is labeled as 1.5", and vice versa).

Also, I couldn’t post links or include media, otherwise I would have included the exact links and an image of mine attached to a GL45 bottle.
I also couldn’t edit my post since its pending approval, hence the double post. Sorry.

Just signed up to give the solution that works for me when I want to rotovap using a GL45 bottle.

I bought one of these for $30: look for the “Stainless Steel Tri-Clamp x Female Joint Adapter” on shopbvv website.
Then used an open-top GL45 cap which are plentiful on Ebay and Amazon).
And a silicone seal for GL45 caps (cheaper on Amazon, look for “Silicone Seal Ring for GL45 Open Top Screw Cap”)

  • Put the silicone seal/ring around the neck of the stainless steel adaptor
  • Slide the neck of the adaptor through the open top cap from the bottom
  • Thread the cap onto the GL45 bottle.

It might be a bit finicky at first to make sure the O-ring makes a good seal, and there isn’t a good way to clip a male 24/40 joint to it using a keck clip, but if you’re pulling a vacuum and using a little vacuum grease, then it works like a charm.

You’re right about that. The forum was preventing me from adding links, images or attachments since I was a new member.

Edit: God damnit, its still preventing me from adding links, lol.

Multiple errors occurred: 1) Sorry, you can’t embed media items in a post. 2) Sorry, you can’t include links in your posts.

I have this nice post written up with images and product links, damn.
