The invention concerns a cassette for an electrophoresis system including an essentially plate shaped body, which includes a first wall for supporting a gel plate, and a second wall for supporting buffer strips, the walls being connected to each other. Further, the second wall is displaceable with respect to the first wall between a first inactive position where the buffer strips are chemically and electrically separated from the gel plate and a second, active position where the buffer strips are in electrical and chemical contact with the gel plate.

Cassette for electrophoresis system

A chromatographic method and device for separating one or several organic substances in a liquid sample. According to the method said sample of substances is passed through a chromatographic device containing as separation medium at least one continuous macroporous matrix. The macroporous matrix comprises a cross-linked organic polymer prepared by polymerization of a high internal phase emulsion system of a water-in-oil emulsion of organic monomers, said emulsion containing at least 75% by weight of water phase. The polymerization results in an open porous structure, to allow a convective flow to pass through the macroporous matrix, whereby said organic substances separate from each other and/or the liquid. The pores of the macroporous matrix are unmodified, or surface modified in a manner that the convective flow is not hampered.

A method of increasing the shelf life of a reversible calorimetric device for indicating carbon dioxide is disclosed, which method comprises placing said device together with at least one non-toxic pH-lowering gas in a gas-tight wrapping or casing. A package is also disclosed which is prepared by means of said method. The invention also relates to the use of a non-toxic pH-lowering gas for increasing the shelf life of a device of the above mentioned type.
