  • Dialysis cell for sample preparation for a chemical analysis method
    Patent number: 11712660
    Abstract: The invention relates to a dialysis cell for sample preparation for a chemical analysis method, in particular for ion chromatography. The dialysis cell comprises a donor channel and an acceptor channel extending parallel thereto. The donor channel and the acceptor channel are separated from each other by a selectively permeable dialysis membrane. In particular, an analyte that is dissolved in a donor solution in the donor channel can enter through the dialysis membrane into the acceptor solution in the acceptor channel. The acceptor channel has at least in some sections a volume that is smaller than the volume of the donor channel extending parallel thereto. Acceptor and donor channels are formed from half-cells, between which the dialysis membrane is arranged, wherein the donor channel and the acceptor channel are designed in each case as a recess in a contact surface of one of the half-cells with the dialysis membrane.

  • Stackable valve system
    Patent number: 8202080
    Abstract: A blow molding machine having the valves integrated into the valve block is disclosed. The valve pistons form annular rings stacked vertically along the stretch rod axis. The valve pistons activate by moving up/down along the stretch rod axis. The valve seat for each vertically stacked valve is formed radially around the stretch rod.
