Hello! My first time on a chemistry forum. My name is Ana . I want to heat up a solution 'till its melting point [300°C] and I want to maintain 50-60 pounds of pressure per square inch [both for a few hours]. How can I do that? I don't want to lose my initial solution quantity. Thanks for your help. Hope this is a good place for my question.

A Parr reactor is the high tech way to go, but it might be overkill for what you need, i.e., the pressures you're working at.

Thanks! You really helped me,

I seem to recall in my graduate school lab that we had a Parr reactor suitable for these kinds of pressures. It was a  glass vessel that just had a regulator that fit on the top of it. We also had a high pressure version, a thick stainless steel monster we affectionately called "The Bomb". Needless to say, working with that thing scared the bejeezus out of me.
