Summa Canister

A Summa canister is a stainless steel vessel which has had the internal surfaces specially passivated using a "Summa" process. This process combines an electropolishing step with chemical deactivation to produce a surface that is chemically inert. A Summa surface has the appearance of a mirror, bright and shiny.
