High-temperature resistant threaded soft stopper
Thread Content
Currently, a experiment is being conducted; due to the special properties of the raw materials, heating is required throughout the transportation process, and the temperature is quite high, around 200°C. If rubber stoppers are used at the connection points between the pipes and the flasks, these stoppers will harden very quickly, which reduces the airtightness of the system. Excuse me, is there any kind of high-temperature resistant ground glass stopper? PS: Soft stoppers can provide a good seal, resulting in better sealing for the system.

If it’s sealed with fire, it won’t be easy to remove. We need to add material to the raw material bottle from time to time
I’ll transfer this to the analysis section for you, to see if they have any better solutions
The polytetrafluoroethylene material is fine!
