Stainless steel migration cell Sieg-Mi-Flex
Stainless steel migration cells are the most commonly used
- temperature resistance -15 °C to 180 °C
- pressure tight up to 9 bar
may be fit with 1 or 2 specimen
- fit with 1 specimen – horizontal storage
- fit with 2 specimen top/bottom – vertical storage
suitable for the following simulants:
(A) Ethanol 10 % Vol.
(B) Acetic acid 20 % weight.
(C) Ethanol 20 % Vol.
(D1) Ethanol 50 % Vol.
(D2) vegetable oil with certain fatty acid distribution from EU Regulation 10/2011 PIM
Replacement simulants:
According to EN1186 and Regulation 97/48/EG replacement simulants which do not chemically react with stainless steel (V4A 1.4571), PTFE and FEP – eg. isoctane and ethanol 95% vol. may be used.

The migration cell Sieg-Mi-Flex consists of a stainless steel fixing plate kit and central ring matching the application in question.
