Re: [DIYbio] Why doesn't someone engineer a simple _____?

Yes, I invented it.
I sell science toys, so I needed a non-toxic replacement for Wood's Metal.
It was just luck that the melting point came in even lower than Wood's Metal.

I then gave the formula to my metals supplier, so I could have them do the measuring and mixing,
saving me the trouble. They decided to carry it in their catalog, and used my name.

Is it seriously named after Simon?  How did you go about creating it?  That's cool...

Presumably contamination is the problem with placing tubes in anything liquid.  Otherwise just pump in pre-heated or pre-cooled mineral oil as a bath and drain when the ramp is complete.  Or as a similar mechanical system, pour in/out pre-heated or pre-cooled lead-iron buckshot.  Mechanical systems though are typically larger, heavier, more unwieldy than electronic systems.

I'll admit though that I've long thought about a simple cooling ramp using ice water and a thermo-sensor controlled pump.  Ice is free.
