Trying to figure out cooling. Options:

New Cole Parmer peristaltic pump w/ LS-15 tubing: 1L/min max
- Warms up tubing at high speeds
DudaDiesel pump: min/max?
- Too much? any chance I could break something?
Small pump
- Test?

Chilling options

FTC-350A from De Anza flea market
- Early tests show that it might not necessarily work: outlet is not any colder than inlet
Large crycooler
- Works
- High current draw
- -100C: potential to freeze water by accident
