There are many choices when it comes to selecting a mixing tank or vessel material. 

 Two main types of mixing tanks, plastic and metal. Poly mixing tanks include High Density Polyethylene (HDPE), Polypropylene (PP), Polyvinylidene (PVDF) and Teflon (PTFE). Metal tanks are usually 304 Stainless Steel, 316L Stainless Steel, Hastelloy C and other exotic metals. We will be focusing on selecting tanks for sanitary or food grade applications which require approval from the FDA.
