Hi everyone,
I was wondering if anyone knows of something that would do the following- almost tow hours of searching have come up fruitless. I need something like an air compressor, but one that is small, and will draw gases from one tube and pump them into another. The problem I am having is I have found many air compressors that can do this, but they draw the air from the air around it, and not from a specific place. Also, it would be preferable if it could handle fairly hot (300*C) gases. I know this seems very specialized but I am in need of some way to pressurize gases into a chamber for my AP Chem summer project. Any other ideas would be greatly appreciated.

Thanks!
