With the help of the Sieg-Mi-Flex migration cells, a migration assessment of packaging ingredients from food repackaging can already take place on the finished roll goods.
\nTests have shown that temperature equilibration by diffusion is sufficient when the migration cell filled with a simulant remains upright for 24 h.
\nThere is no need to turn around. The migration cell is easy to close or open with stainless steel knurled screws. Their compact, space-saving design can be stored horizontally or vertically for temperature control in drying ovens or bath\/circulating circulators.<\/p>\n

In the Sieg-Mi-Flex migration cell system, many sizes and thicknesses of packaging in a wide variety of material compositions can be tested with all liquid and solid food simulants.
\nFor studies with solid food simulants (E) poly-2,6-diphenyl-p-phenylene oxide (MPPO), the Tenax kit is used. Some customers also use the Tenax kit for migration testing with oil, as the fixing plate with the GL45 spout is easier to clean in the dishwasher than the center rings with the GL14 pour-in and GL14 pour-out spouts.
\nThe Sieg-Mi-Flex MIgration cell is then subjected to the test conditions with one test piece lying horizontally at a time. Due to the high temperature resistance (-20 \u00b0C to 180 \u00b0C) and the high pressure tightness up to 9 bar, stainless steel migration cells System-Siegwerk (Sieg-Mi-Flex) can also be used for liquid food simulants under test conditions beyond their boiling point.<\/p>\n

<\/span>Application examples<\/span><\/h4>\n

 <\/p>\n

Migration cells of the Sieg-Mi-Flex type are basically suitable for migration tests, among others according to EN1186. Migration tests can be performed with cloths, papers, foil or cardboard packaging, gloves and many other materials or surfaces.<\/p>\n

\n

The following simulants can be used in the migration cell “Sieg-Mi-Flex”:<\/p>\n

(A) Ethanol 10 % vol
\n(B) Acetic acid 3 % wt.
\n(C) Ethanol 20 % vol.
\n(D1) Ethanol 50 %Vol.
\n(D2) vegetable oil with specific fatty acid distribution from VO EU 10\/2011 (PIM)<\/p>\n

Also, according to EN1186 and Directive 97\/48\/EC, substitute simulants such as the solvents isooctane and ethanol 95 % vol. can be used, as well as other alternative simulants that do not chemically attack the materials stainless steel (V4A 1.4571), PTFE and FEP (tetrafluoroethylene-hexafluoropropylene copolymer).<\/p>\n<\/div>\n

<\/span>Cleaning migration cells<\/span><\/h5>\n

 <\/p>\n

The Sieg-Mi-Flex cells are completely disassembled for cleaning and left for approx. 15 min. sonicated with isopropanol at room temperature in an ultrasonic bath, then dried. Then rinsed with ethanol pure LC-MS quality and dried again.<\/p>\n

The individual parts of the Sieg-Mi-Flex migration cell are dishwasher safe<\/p>\n

The migration cell system Siegwerk (Sieg-Mi-Flex) following EN 1186-1:2002 (D), Annex C (informative), Figure C.4-Cell Type B and Figure C.5-Cell Type C, was developed and tested in cooperation with the analytical department of Siegwerk Druckfarben AG & Co.
