Scentroid is the only manufacturer in the world to offer stainless steel sampling bags. Each stainless steel bag is made of electro-polished marine grade (316L series) stainless steel film. Stainless steel sampling bags are ideal for sampling corrosive materials such as high H2S or benzene. The stainless steel is rolled into a thin film that provides it with flexibility while maintaining the %100 sample preservation. Scentroid stainless Steel bags are used commonly instead of Sumo canisters.
