Maybe @Roguelab or @Dr_Jebril could help you source something in Europe.
Thanks for the tip, I texted each one, fingers crossed
You should be able to get this from lab glassware suppliers, locally, such as VWR, Carl Roth, Huberlab etc. Should write them an email because it may not necessary appear in online catalogue.
Otherwise there is China. Many suppliers there, such as Lab1st.
Or as suggested above, local glass blowers. This is the nicest solution.
Thanks anyway
Searching but in the mean time the tapering on these glass or ptfe is very similar to what you need might be an option as plug with grease
In fact we forgot about the best glass supplier.
You should try with @david .
He will have this, heās fast and reliable.
Look up here @david glassware and adapters sales section
Okay, Iāve found who can weld the glass stopper. One more thing or a suggestion for a diaphragm pump capable of being effective for pumping about 20 grams of concentrate into the 50ml flask?
Can this pump fit?

sure, but you needed to be PRODDED to provide Italy.
guess what. the all knowing one can also be prodded thusly.

viola:

yep. for that wee rig it should work just fineā¦
see: 500ml or 2L - #17 by cyclopath for illustration.
Thanks for the tip, @cyclopath in the links you gave me glass stopper 10 18 - Google Search Did you manage to see anything? I donātš
yes and no.
there are at least a couple of lab glassware links that come up on the first page with that search.
at least one I checked had stoppers, but only in 10/19.
came to the conclusion that the Italians either use their very own set of stopper sizes, or call them differently.
figure thatās and exercise for the reader
Edit: (my reading of that link suggests itās just a nomenclature glitch, but only way to know it to try itā¦).
Still reckon that 12mm ptfe rod in a variable speed drill with a sharp tool and a steady-rest would solve it.
Not certain you couldnāt just warm the joint just right and stuff it in!!!
First learning test, this is my setup, 50ml boiling flask with about 15 grams of bho concentrate, Chinese mantle, china distillation head dry run, 9 cfm 1hp two stage rotary vane pump. No right pressure gauge to avoid any leaks, despite this my condenser and the receiving balloon are always dry, what suggestion do you give me?
