I’m not sure if this is posted in the right place but maybe someone will be able to help.
I have a 50L rotary evaporator that needs a new evaporating flask gasket. If I Google this item I can find multiple where it is being sold. Some sale it as a set and some sale only the gasket (reddish colored). I’m willing to buy either. The problem is that every site that I have found has them back-ordered or no longer available. Does anyone know where I can get a replacement? I am attaching a picture of the seal that needs replacing.
This seal is two pieces as you can see in the pic. I have seen the parts sold individually or as s set.
