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.
