    Low-Cost Research Glove Box

    Nicely laid out and designed project. However, I have to second en2oh's comments about the side tunnel not being an airlock. On the other hand, having an airlock is a moot point if you have the heat gun forcing all of that outside air into the box. The additional air does not appear to have any way to escape, and besides contaminating the experiment, could force the contaminated air out into the room. This is also a problem with the humidifier introducing outside air. It would be a much better idea to have a small ceramic heater installed into the box, that way you would recycle the air inside the box through the heater. An even better idea would be a computer fan blowing the air through a copper-coil which has temperature controlled water circulating through it. This way you could both...

This way you could both raise or lower the temperature without introducing outside contaminants. I also am not understanding the purpose of the saturated salts in the humidistat. I would also recommend having some way to get electrical power into the glovebox. You always need power, whether for mixing, hot plate, etc.
