Move fluid from here to there with this very nice elastomeric silicone tubing, specifically for our peristaltic pump. It's one meter long and fully silicone with the correct diameter to give great peristaltic performance.
This silicone tubing is not sterile and might get a lil' dirty on its way to you. So, before first use, we recommend it be sterilized by boiling in water, etc! The tubing is neither FDA nor USDA-compliant certified. If you need FDA/USDA-certified tubing for use with your food-hacking project, check out McMaster-Carr. They have many types of silicone tubing available!
Wikipedia has a great article on peristaltic pumps. Please check it out for more details on how these devices work!
