I am trying to test chemical reactions, more specifically reactions between an acid and a base, at different levels of pressure.

I would like to know if there is some kind of equipment I can get that has adjustable pressure, and will let me get the reactants into the vessel without changing the pressure significantly.

I am looking for something that I just get at home, so not too big, and hopefully not too expensive. It doesn't need to be super high-tech, as I'm not going for a high level of accuracy, and I'm not going to be testing extremely low or high pressures.

Does anyone know of any equipment that will create significantly different levels of pressure, even if it is very expensive?

  • $\begingroup$ What kind of pressure ranges did you have in mind? $\endgroup$ – feetwet Feb 13 '16 at 16:32
