Please respect those from whom you are requesting help by writing in words.
Here's one way. Find two old glass jars which can be nested, like a pickle jar inside a mayonnaise jar. Seal the opening between them, perhaps with wax, and pump out as much air as you reasonably can. You haven't said what a CDT is, but for a simple science experiment, you could compare heat loss between this and an identical pickle jar without the air or vacuum chamber. Fill both with hot water at the same temperature, and measure the temperature drop over time, with identical insulating lids over both.

I made a 6x6x6" vacuum chamber out of 1/2" thick plastic held together with window caulking. Then I fashioned a nozzle so that I could attach a hand-held vacuum pump that you can get from Edmunds. I could pull enough vacuum to pull water up about 30ft. That's equivalent to about 50,000 ft altitude.
