designing titanium pressure cooker, 2,5 L (85 fl oz), 50 bar (725 psi) and 250¦C (482¦F)

[swiss037]

hello,

I'm and working on a 2,5 liter titanium container for pressure cooking an acidic solution, up to 50 bar and 250°C.
In US units, that would be 85 fl oz at 725 psi and 482°F (I'm in Switzerland).

2 options should be considered:
a) passive container for use in an oven
b) stand-alone heating system

Questions:
1. Have you ever seen something like that?
2. What sealing/opening system would come to mind, for daily use in a lab?
3. How much do you think such a product could cost, very approximately?
4. For option b), would you rather recommend usual resistive heating or have you ever heard of something less usual like induction?

I just discovered this forum, whose other threads I will thourougly browse in the next few days.
thanks a lot for reading!

I have certainly seen high pressure lab equipment that sounds like what you are dealing with.

One manufacturer that comes to mind is Autoclave Engineers. They make a vessel that sounds like it would be exactly what you're looking for. They have some various designs that are quick-opening, no-tool opening, etc...

Cheers,

thank you very much, marty007.

Parr Instrument Company is another option- far more economical than Autoclave in my opinion. Anything titanium will be custom regardless who sells it.
