  • Patent number: 8153059
    Abstract: A chip-holder for holding a micro-fluidic chip has a fixer for detachably fixing the micro-fluidic chip in the chip-holder and at least one process control device configured to support control or monitoring of a chemical process in the micro-fluidic chip, wherein the chip-holder is configured such that the process control device and the micro-fluidic chip are directly and detachably coupled when the micro-fluidic chip is fixed in the chip-holder. Such a chip-holder brings along the advantage that the micro-fluidic chip can easily be removed and exchanged while the process control device can be reused. This reduces running costs of a chemical microreactor system drastically and allows for a very flexible usage of a chemical microreactor system.

    Abstract: A chip holder for holding a fluidic chip and for providing a fluid connection thereto has a guide adapted such that the fluidic chip can be slid into the chip holder in a guiding direction. The chip holder further has a fastener adapted to press a fluidic connection toward the fluidic chip, such that the fluidic chip is fixed within the chip holder. The guide and the fastener are adapted such that the guiding direction and the direction in which the fluidic connection is pressed exhibit an angle in the range between 45° and 135°, including 45° and 135°. A fluidic system has a chip holder and a fluidic chip inserted therein. A chip holder system has a chip holder and an extension module attached thereto such that the extension module is in contact with the fluidic chip, when the fluidic chip is inserted in the chip holder.
