I want
a glove box/flow hood, Commercial glove boxes seem to start at about 1000$
a scientific hotplate for exact temp control
an induction hotplate for rapid meltingan IR thermometer
a flow regulator and lines for the shield gas
a bottle of argon
a couple graphite crucibles
a refractory board to protect the plastic in case of spills
Kaowool to insulate the crucible to slowing cooling for crystal growth testing
gloves that attach permanently to the box and create part of the seal
some oven mitts (the industrial kind)
I could probably get away with, several less exact options for this testing but I would hate to figure out I needed a proper glove box 3 weeks into the project.
My design so far is a box with a slanted front for viewing. Currently I'm aiming for 24L X 20W X 18-30H
18 inches at the front 30 in the back.
I'm planning on the following
Black ABS for the sides, base and back. I would prefer white for thermal reflectivity, but the thicknesses I want seem scarcer and therefore more expensive. ABS has good thermal properties which are a concern for this project.
The front, and top will be clear Polycarbonate. This plastic is fairly stable thermally and will put up with the mechanical wear, and stresses of the glove holes very well.
At tap plastics the pre cut pieces would run me just around 220$ for materials and another 40$ or so in labor to laser cut the parts to proper shape.
The box also needs gloves. These are usually attached inside and outside of the box with a pair of circular gaskets.
It would look something like this...
I will need power and a gas connector, valve on the exit.
Last bit is the tricky bit of opening and closing the box while still being able to seal the box.
