The invention relates to an alumino-borosilicate glass for confining a radioactive liquid effluent having medium activity.

The convex glaze layer (2) and the electrode forming glaze layer (3) are formed of amorphous glass.

The sealing layer is heated and a metal strip is pressed on the sealing layer.

The electrode forming glaze layer (3) is formed to be thinner than the convex glaze layer (2), whereby the electrode forming glaze layer (3) can be formed at a lower temperature than the convex glaze layer (2).

It is no longer necessary to sinter the electronic components.

The present invention relates to a method of vitrification of a biological specimen.

Also disclosed are an automatic operation device for rapid vitrification freezing of living cells and a carrier for rapid vitrification freezing of living cells.

The embryos may be cryopreserved by vitrification or conventional freezing.

Since consumption and burning of a probe are prevented, highly reliable wafer level burn-in method and system can be provided.

Thereby, also agglomeration, sintering or vitrification of the particles is prevented.

The sealing layer is then cooled, whereby the metal strip is left in contact with the surface of the sealing layer until the same has hardened.
