Definitions

  • the invention relates to a rotary unit for a rotor of a dual centrifuge according to the specified in the preamble of claim 1.
  • Rotary units for a rotor of a dual centrifuge are known in the prior art, which can be arranged individually or in a plurality in the rotor and in which, for example, sample material-containing centrifuge tubes are mounted in a sample container receptacle of a receiving unit.
  • a secure storage of the sample container during centrifugation is often only achieved in that the receiving unit engages relatively far in a rotary head of the rotary unit, so as not to be thrown by the forces resulting from the rotation of the turret. This has a disadvantageous effect on the size.
  • a safe storage in a turntable is not easy to implement or not possible because the sample tube for certain tasks must be placed horizontally in the turret.
  • a dual centrifuge which has a rotary head and a receiving unit.
  • the receiving unit and the turret are positively connected with each other, which due to the tolerances leads to small relative movements and thus to additional imbalances in operation. These imbalances in turn lead to severe wear during operation and thus premature failure of the centrifuge.
  • the object of the invention is therefore to provide a rotary unit while avoiding the disadvantages mentioned and to develop such that sample material can be safely inserted into a container, eg a tube by means of a recording unit with only a small footprint in the rotary unit, and further optimized different Sample container receptacles and to
  • the invention is based on the finding that a frictional connection / clamping connection between the receiving unit and the turret allows safe storage and easy replacement of the receiving unit. In addition, thereby the space can be further reduced.
  • the rotary head is rotatably connected to a receiving unit releasably connected, in which at least one sample container receptacle is used, which contains the sample.
  • the connection of receiving unit and rotary head is formed by a frictional connection, in which the receiving unit and the rotary head partially wedge-shaped engage in each other and the adhesion during a movement of the
  • Recording unit increases along the axis of rotation of the rotary unit in the direction of the rotary head.
  • the requirements for wedge-shaped traction connections are technically easy to implement. An operator can then easily and without tools produce the frictional connection / clamping connection between the turret and receiving unit and solve again.
  • the rotary unit is mounted obliquely in the rotor and arranged so that with increasing rotation, the receiving unit is pressed into the frictional connection.
  • forces generated during the rotation are used to reinforce the wedging of the receiving unit with the rotary unit. In this way, regardless of the
  • Rotation speed ensures a simple and secure determination of the recording unit in the turntable.
  • the frictional connection between a bottom of the receiving unit and an end face of the turret is effective. So is the wedge-shaped
  • Frictional connection particularly easy to produce because the wedging / jamming is done mainly by the insertion of the receiving unit and the release of the wedge-shaped
  • Friction connection are provided. By the stops is achieved that the receiving unit covers only a defined maximum path in the turret. So will the
  • the frictional connection of receiving unit and turret includes
  • Receiving unit the feet and the turret having the recesses or vice versa. It can also be provided in the receiving unit and in the turret both feet and recesses.
  • the conical shape of the feet ensures a good wedge action / clamping action and high shear strength, and the tapering in the direction of the recesses outer contour of the feet also serves for easy centering of the feet in the recesses.
  • the longitudinal axes of the feet are aligned parallel to the axis of rotation of the rotary head and the feet are rotationally symmetrical, one by a longitudinal section through the resulting line of the cone shroud at an angle of 10 ° to 35 °, in particular 15 ° to the axis of rotation is employed.
  • this angular range is the ratio of
  • Shear strength of the feet on the one hand and wedge action / clamping action on the other hand particularly favorable. Furthermore, the feet can fit well into the turret when inserting the receiving unit into the turret
  • Recesses are centered.
  • the feet and the receiving unit are integrally formed of the same material and / or the feet and the rotary head in one piece, formed of the same material.
  • the number and dimensions of the feet are tailored to the shear strength of the material of the feet in conjunction with the forces resulting from the rotational cycling load during operation with the dual centrifuge. This can prevent that due to insufficient number and / or dimensioning of the feet to an unwanted solution of the wedge-shaped frictional connection during the centrifuge operation and thus damage within the centrifuge.
  • material costs and construction costs can be reduced, since only the number and dimensioning of the feet required for safe operation is provided.
  • the diameter of the base of the truncated cone of a foot to the height of the truncated cone has a ratio of 10: 6.
  • the material used for the receiving unit plastic, in particular polyamide, and for the turret and the sample container receptacles aluminum in particular the aluminum alloy EN AW-AI Zn5Mg3Cu-T6 used. Strength, processability and cost of these materials are in a particularly good relationship to each other.
  • the rotor is driven by a drive shaft.
  • the drive shaft can be made of aluminum or of steel or coated with steel. Particularly simple is a safe and stable frictional connection is made possible by the fact that an even number, at least four, rotationally symmetrically arranged and evenly spaced feet is provided. In addition, this rotationally symmetrical arrangement counteracts the occurrence of imbalances.
  • the receiving unit is preferably constructed symmetrically, so that the receiving unit can be inserted in two instead of only a single position in the rotary unit. When the feet are located at the edge of the receiving unit, the shearing forces acting on the feet are less. This results in a lower material load and thus safe operation of the turret.
  • the storage of the receiving unit can be made even safer, that the turret is provided with an upwardly open safety pot, the receiving unit, in particular with the introduced into the sample container receptacle sample container or in the
  • Sample container receiving introduced sample containers in the assembled state completely surrounded laterally.
  • a breaking of the receiving unit in a direction lateral to the axis of rotation is prevented if the wedge effect / clamping effect of feet and recesses is lost, for example, due to material defects.
  • leakage of sample material from the safety pot e.g. after destruction of a sample container, counteracted if this is formed completely closed.
  • a circumferential safety channel for receiving escaped sample material is introduced. Spilled sample material is trapped in it and can spread. This avoids accumulation of spilled specimen at a location that could be a source of imbalance.
  • a, in particular completely closed, lid is provided for the safety pot, which is preferably connectable to it via a quick-release fastener or a screw connection, the rotary head and especially the bearing connected to the rotary head and the rest of the interior of the dual centrifuge are protected from contamination, if a receiving unit and the sample container contained therein are damaged, since a spattering of the sample material is prevented.
  • the lid can provide further protection against breaking out of the
  • the bottom of the safety pot has the feet and / or recesses for connection to the receiving unit.
  • Safety pot is easier to seal.
  • the safety pot is connected to the turret via fastening means, in particular riveted. This ensures that the safety pot does not detach from the turret during operation and damage the centrifuge.
  • the turret and the safety pot are formed as an integral, one-piece and material-unit component. By reducing the number of components, the system becomes more stable.
  • the safety pot is completely closed, as it is advantageous if the lid is completely closed.
  • the wedge-shaped frictional connection is effective on a side surface of the receiving unit and on a peripheral wall of the safety pot.
  • the sample container receptacle is inserted into the receiving unit and is detachably arranged there.
  • Receiving unit and sample container receptacle are thus formed in two parts.
  • Sample container receptacles for sample containers and / or loads is provided, wherein the respective receiving unit is optionally used in the turret. This ensures that a wide range of sample containers can be processed in varying numbers and always suitable sample container receptacles for sample containers are available, which are secured by strong wedging / jamming secured in the turret.
  • the receiving unit has a receiving space with two legs for two different sample container receptacles.
  • the number of required different recording units can be reduced by half.
  • the sample container receptacle is stored without play in the receiving space of the receiving device by a tensioning device.
  • a detachment of the sample container from the Recording unit prevents what increases the safety of the centrifuge during centrifugation and minimizes the risk of damage and contamination in case of failure.
