[Reward Delivery] Prevent Bacteria Growth

[Lily]

My lab is thinking about rewarding mice with sugar water instead of normal water, but we are worried about bacteria growth in the delivery tubes. Does anyone have good suggestions to prevent bacteria growth in water delivery systems?

Hi Lily,

One option is to use a pinch valve (e.g. part 225P011-21, here) with silicone elastic tubing (e.g. this), and throw away / replace the tubing as needed.
