Hey everyone so I had my receiving flask implode on me last night. I purchased this rotovap from DHgate. It is a 20L and the flask is a 10L. Can I purchase buchi, AI or usalabs glass or am I stuck ordering from China?
Edit wow I guess I didn’t read the first sentence.
How did it implode!?
I believe you can order any replacement as long as it has the correct flange.
I have the same roto. Zzkd has good support, they will probably get it to you a lot cheaper than those American companies.

This looks different from the one i’m using. Which is why I was curious - mine has 3 ports on top and they are all the same size. This one has 3 ports and 2 are the same and 1 is different.
Honestly i’m not sure but my best guess is a slight vacuum leak where the stopcock is located. And I’d love to wait on them but I need it basically asap. I was in the middle of filling an order when this happened so i’m halfway done and have a bunch of inventory that needs evaporated!
Get your joint measurements and overall dimensions and send em to @htking or @david either can help you pretty quickly. I recently had david make me a 5L Roto ball that fits on a 5L USA Lab roto. It was straighter than the two USA Lab sourced ones that i have and cheaper too

@david is the 
If you need one like right now I bet that the companies you mentioned before will fit. But I highly recommend David.
