I dunno im experimenting with cold its not a spec I just need stuff that is generally good.
the lowest temperature would be dry ice slurry.
Would not mind picking up a few different coolants so long its cheap. Its small stuff like 1/4 inch tubing
Since its stupid bullshit, I would say 200$ a gallon and I don't know anything about how to define viscosity. so it flows good in tubing, I don't actually know what the limits are. I just notice its kinking my silicone tubing when I use glycol stuff and it gets cold enough, its like pushing slurpee. I hooked it up with some stiffer tubing but that setup is not acceptable, I want it like test leads. I was hoping with maybe methanol I can use silicone tubing at lower temperatures. When it has the braided reinfroced tubing I am inclined to bury it in the yard because its just shit.
this one is with a gear pump
