I wonder if all the parts they are using are alcohol-safe. That tubing would preferably be platinum-cured silicone (which is expensive). PVC is not a good idea

- fr0sty 14y agoThey say "food grade" but don't specify further. The pumps are peristaltic[1] though so the only part that touches alcohol is the tubing so it is simple to swap out for another material. [1]http://en.wikipedia.org/wiki/Peristaltic_pump http://en.wikipedia.org/wiki/Peristaltic_pump
- gallerytungsten 14y agoFood grade and alcohol safe aren't always synonymous. Peristaltic pumps are good, and they usually require soft hose, such as silicone.
