Definitions

  • the present invention relates to a device for storing in a cryogenic container tubes having different heights, device of the type comprising a superposition of removable drawers sliding in a frame. It applies in particular to the storage of biological products in liquid nitrogen.
  • the tubes intended for the cryogenic storage of biological products such as animal or human seeds normally have a standard diameter but different heights, corresponding to samples of 2 ml and 5 ml. It is therefore currently necessary to have two types of storage devices, one for each type of tube.
  • the invention aims to provide a storage device offering great flexibility thanks to the possibility of simultaneously storing and in variable proportions the two types of tubes.
  • the subject of the invention is a storage device of the aforementioned type, characterized in that the chassis comprises at least one rack adapted to receive at least two drawers and, between them, a removable intermediate horizontal partition.
  • each drawer is provided, at an intermediate height, with a tube positioning grid, this grid comprising, for each tube, a hole which can be freely traversed by it and surrounded by reliefs for lateral support of the tube. It is then advantageous for the grid to be removable and retumable.
  • the storage module 1 shown in the drawing is intended to hold a number of tubes 2, 3 for preserving biological products in a container (not shown) filled with liquid nitrogen.
  • a container not shown
  • several modules 1 are stacked and fixed to each other, for example by welding or clipping, to occupy the entire height of the container, the upper module being equipped with a handle.
  • the module 1 shown has, in plan, a rectangular shape, it can also have another shape, for example triangular, so that all the stacks of modules make the best use of the space available in the container.
  • the module 1 comprises a rack 4, two drawers 5 each equipped with a grid 6 (the upper drawer and the grids 6 have not been shown in FIG. 2, for the sake of clarity of the drawing), and a partition 7 All these elements are made of a plastic material adapted to withstand cryogenic temperatures.
  • the tubes 2 and 3 have a common diameter, but the tubes 3 have a height approximately twice that of the tubes 2. They are intended to store samples of 2 ml (tubes 2) and 5 ml (tubes 3) respectively.
  • the locker 4 is parallelepiped and open on its front face. Its upper and lower faces are full, and its three other faces largely perforated by pairs of windows 8 separated by horizontal members 9 located halfway up the rack. Each lateral member has an internal groove 10, and the rear member has a snap-in recess 11.
  • Each drawer 5 is open upwards. Its front face 12, of reduced height, has a central tab 13 for gripping. On its inner periphery, the drawer has a number of vertical ribs 14 extending approximately halfway up. Furthermore, although this is not shown, the drawer has at its bottom at least one opening for draining liquid nitrogen, and also external snap reliefs for keeping it in position in the rack.
  • Each grid is associated with a grid 6, a corner of which is shown in FIG. 3.
  • This grid has a large number of circular holes 15 whose diameter is slightly greater than that of the tubes 2 and 3 and, between these holes, a large number cylindrical spikes 16 arranged so that each hole is surrounded by three spikes 16. The height of each spike is slightly less than half that of a drawer.
  • the partition 7 is a rectangular plate, the lateral edges of which are adapted to slide in the grooves 10 of the rack and the bitter edge of which has a snap-in relief 17 in the recess 11.
  • each tube 2 of 2 ml is stored in a first mode of use of the module 1, illustrated on the left half of FIG. 1, tubes 2 of 2 ml are stored.
  • the corresponding grid 6 is placed on the ribs 14, with the pins 16 facing downward, and the tubes 2 are placed in the holes 15.
  • each tube 2 is kept in the vertical position and can easily be grabbed by its upper part to be extracted.
  • the partition 7 is put in place, the lower drawer 5 is inserted under the latter, bearing on the lower bottom of the rack 4, and the upper drawer 5 is inserted above the partition, bearing on the latter.
  • the height of the tubes is such that each rests on the bottom of the corresponding drawer and rises to a level slightly lower than the wall which surmounts it: the partition 7 for the tubes 2 lower, the upper wall of the rack 4 for the upper 2 tubes.
  • the tubes 2 When all of the modules 1 are immersed in liquid nitrogen, the tubes 2 tend to float on this liquid and therefore to rise. They are retained vertically, one by the partition 7, the other by the upper wall of the crate, and laterally by the pins 16 (which, as a variant, could be replaced by cylindrical collars). It can be seen that one or the other of the drawers 5 can be extracted without disturbing the positioning of the tubes 2 of the other drawer, thanks to the double role of the partition 7: support of the upper drawer on the one hand, retained vertical of the lower tubes on the other hand.
  • module 1 used for the storage of tubes 3 of 5 ml, is illustrated in the right half of FIG. 1: the upper drawer is removed, and the grid 6 of the lower drawer is supported on the ribs 14 of the latter, but, this time, with the pins 16 facing upwards.
  • the long tubes 3 are arranged in the holes 15 and extend from the bottom of the lower drawer to a location close to the upper wall of the rack 4. More precisely, the distance separating this wall from the upper end of the tubes 3 is significantly lower than that which separates the bottom of the drawer from the top of the pins 16.
  • the tubes 3 When the model is immersed in liquid nitrogen, the tubes 3 tend to float on this liquid and therefore to rise, but they are retained vertically by the upper wall of the rack 4 and guided laterally by the pins 16. Thus, again, the arrangement of the tubes is not disturbed.
  • each module could have three drawers and two intermediate partitions, to further increase the possibilities of use.
