Stainless steel
Stainless steel is the name for alloyed or non-alloyed steel that show an outstanding degree of purity and are non-corrosive. Other names are austenitic steel or inox steel. For our safety containers we use high quality types of stainless steel that are characterised by a high chemical resistance due to their alloys. The use of our safety containers is especially recommended when flammable or dangerous liquids or are used or/and when safety requirements are high. The company Thyssen-Krupp gives a detailed overview of chemical resistance for different types of stainless steel (for comfortable reading in Acrobat Reader please go to page 2, than select view - page view - two pages). You will find the type of stainless steel we use for our products in the respective technical data sheet of each product.

Synthetic materials
For gaskets in our products, we use different, highly chemically resistant synthetic materials. The container gaskets are made of PTFE (polytetrafluoroethylene), content level indicators of PFA (perfluoralkoxylalkane) - both are fluorinated plastics, well known under the name Teflon (trade name of the company Dupont (U.S.)). Gaskets of our safety funnels are made of PE (polyethylene) or Alveocel. You can find a detailed overview of the chemical resistance of different synthetic materials here.

Note: Information about material resistance are based on current findings/expertise about pure substances. In practice, however, several factors in the users context can have influence, e.g. concentration, temperature, pH, etc. Therefore, when using non listed or impure substances the customers needs to test material resistance before using the container.
