Default WCing in my chemistry lab

One of my colleagues (a physicist) had a rather interesting research problem that required using a relatively high power TEC. He asked me if I had ever heard of peliters

Anyway, I am flying down to Chicago for a couple days to do some preliminary experiments at Argonne National Lab, and so I setup the Maze 3-1 today. I happened to notice that the bolts that hold the copper top down stick out into the base of the block. So it is not possible to use a 50mmx50mm TEC, as the bolts interfere. No worries, I just used some washers I had lying around the house.



This may have been an isolated incident from getting a poly block with a copper top instead, or it could be a common issue. You could also solve it with shorter bolts. I am also using a 169W TEC (12V and 18A) and a Tt 420W PSU to push it (that's all I have around the house).

Here is the obligatory pic with frost:



So I'll see you guys Thursday night after some cool (arrgh a pun) science is done.
