  "title": "Reaction chamber system for chemical synthesis or related applications",
  "abstract": "In a reaction chamber is located a platform for receiving individual samples and sample racks. The reaction chamber can be heated, cooled and evacuated. The samples are then radiation heated. The sample platform is shaken by magnetic coupling. The individual sample containers/reaction containers may be filled or emptied in use thorough ducts. The system has applications in the field of chemical combinatory synthesis, as evaporator or for related applications.",
  "claims": [
    "1. Reaction chamber system for the simultaneous processing of a multitude of liquid, or liquid solutions of, aggressive or hazardous samples, comprising a closed reaction chamber with bottom plate, a platform freely standing on the bottom plate inside the chamber for receiving individual sample containers, with magnetic means fixedly connected to the platform, and a shaking drive, located outside the reaction chamber and being equipped with magnetic driving means providing magnetic coupling to the magnetic means connected to the platform, for driving the platform by the said magnetic coupling.",
    "2. Reaction chamber system according to claim 1, wherein the chamber is provided with means for being emptied.",
    "3. Reaction chamber system according to claim 1, wherein a radiant heater is mounted on the outside the chamber.",
    "4. Reaction chamber system according to claim 1, comprising line connections for filling and emptying the sample containers during processing.",
    "5. Reaction chamber system according to claim 1, comprising electrically non-conducting inserts which prevent the eddy current braking effect in the magnetic coupling area.",
    "6. Reaction chamber system according to claim 1, wherein the reaction chamber has a bottom plate with bearing shells mounted therein and the platform is equipped with bearing journals having a smaller diameter than the bearing shells and standing freely in the bearing shells.",
    "7. Reaction chamber system according to claim 6, wherein the shaking drive is equipped with a multitude of rotating synchronized drivers with driver magnets, and the bearing journals are equipped with integrated shaking magnets.",
    "8. Reaction chamber system according to claim 7, comprising a driver magnet which repels the shaking magnet so that friction decreases as the shaking speed increases."
