Material for container HF 21% v/v

Hello friends

I will use HF for some process, and I want to know which are the best material for the construction of the tanks.

That is a nasty acid (at that strength) to be working with. I used rotationally molded polyethylene tanks that were reinforced with good luck with 15% HF solutions. PE is a good plastic and the molded tank does not have any welded areas to fail. PE tanks will work better than polypropylene tanks at room temperature.
