Definitions

  • the invention relates to a water bath shaker according to the preamble of the main claim.
  • Such water bath shakers are known in a large number of embodiments.
  • a known embodiment has a drive in the water, which has the disadvantage that corrosion occurs at the bearing points.
  • the manufacture of the water bath shaker is complex because of the encapsulation of the drive, although the tub can be completely and well covered with a lid, so that not only too much heat is lost as a result of the open tub, but a closed volume, e.g. a pure nitrogen atmosphere can be achieved with the exclusion of oxygen.
  • the tray is driven by means of drive means reaching into the tub from the outside (water bath shaker G 76 / D, New Brunswick Scientific Company).
  • This known water bath shaker is not as complex as the first-mentioned embodiment, but it results in a tray that is not so well balanced and the fact that the tub cannot be covered well.
  • a similar water bath shaker is also known (DE-A-2120435).
  • the invention is therefore based on the object of designing a water bath shaker with a simpler and more balanced drive.
  • the water bath shaker designated overall by 5, has a housing 6 and, in the lower region thereof, a drive designated overall by 7.
  • the housing has a rotationally symmetrical trough 8 with a receiving area 9 for the water 10 in the form of a closed ring with a central passage 11.
  • a drive shaft 12 extends through the passage, at the upper end of which a closed, inverted hollow cylinder 13 is fixed with its end face 14.
  • the free end of the hollow cylinder 13 is adjoined by an overall circular tray 15, on which an Erlenmeyer piston 16 can be arranged as a container by means of a fixing device (not shown), which is exposed to a circular shaking movement which the tray executes.
  • the drive shaft 12 performs an eccentric circular movement about its axis 17 parallel axis of symmetry 18 of the tub 8.
  • the drive axis 12 rotates with its eccentric circular movement in one direction of rotation about its own axis 17 in the other direction of rotation - in terms of the amount - in each case the same speed, whereby the circular shaking movement of the tray is generated.
  • the tub 8 is covered by a cover 19 in total.
