    An account is given of a centrifuge apparatus with a plate-like rotor whose outer edge is used as stops for radially placed sample tubes. For keeping them in position against the stops the radially inner ends of the tube are pressed downwards in the middle of the rotor plate for changing the slope of the tubes to go through a dead center position. A hub in the middle of the rotor is joined with a driving shaft by a coupling. A nosepiece for use with a locking part is arranged on a part, fixedly joined to the driving shaft, of the coupling.

    The invention relates to devices used to analyze liquid samples contained in tubular vessels. A device for analyzing liquid samples is known, comprising a plate-shaped rotor having radial grooves for accommodating tubular containers with liquid, samples, scales of indications and counter-supports in which elastic damping elements are installed and. This device does not provide the ability to quickly change tubular containers with samples, which complicates its maintenance. The closest to the technical essence of the invention is a price robust device for analyzing liquid test samples containing a disk-mounted rotor mounted on the drive shaft, having radial grooves for accommodating tubular containers with samples, a clamping element mounted with moving along the axis of the rotor and interacting with the locking protrusion made on the end surface of the hub of the rotor 2. A disadvantage of the known device south is the inconvenience of servicing the device, since no replacement of the rotor plate is provided. The aim of the invention is to increase the convenience of operation by providing the possibility of replacing a disk-shaped rotor, which allows cleaning the contaminated after repeated installation of the tubular capacities of the rotor after its removal from the device. In addition, the replacement of a rotary container worn out after a long service life does not cause difficulties, which is of particular importance with regard to the cost-effectiveness of maintenance and replacement of parts. This goal is achieved by the fact that in a device for analyzing liquid liquids containing a disk-shaped rotor mounted on a drive shaft having radial grooves for holding tubular containers with samples in them, a clamping element mounted for movement. along the rotor axis and interacting with the fixing protrusion made on the end surface of the rotor hub, the hub is made in the form of a gear coupling, the driven element of which is coupled with the rotor plate, and the driving gear is fixed to the drive shaft and a fixing protrusion is located on this element. The drive coupling member is mounted on the drive shaft in its middle part, and the protruding end of the shaft is the rotor. FIG. 1 shows a drive shaft} in FIG. 2 is a plan view of a disc-shaped rotor; in fig. 3 shows section A-A in FIG. 2; in fig. 4 and 5 are two different operating positions of a rotary-mounted rotor. The centrifugal device for analyzing liquid samples contains a plate-shaped rotor 2 mounted on the drive shaft 1, having four radial grooves 3 for accommodating tubular CTB1X tanks 4 with samples. Inside the rotor hub, which is the follower element 5 of the coupling, there are several connecting grooves 6 and a pilot hole 7 in which the drive shaft 1 is mounted connected to the housing 8. On the shaft 1 the coupling leading element 9 is rigidly fixed, on the perimeter of the central zone of which the connecting teeth 10, and the locking protrusion 11 is made on the bottom end surface. As soon as the rotor plate 2 is seated on the shaft 1, the connecting teeth 10 enter into the coupling required for transmitting torque These grooves 6, the rotor plate 2 with its abutment surface abutting against the upper surface of the locking tab 11. The protruding end of the shaft 1 is the axis of the rotor. The clamping element is mounted on the shaft 1 with the ability to move along the rotor axis. 12, along the perimeter of which four slots 13 are made to receive closed 51 ends of tubular containers 4. When the clamping element 12 is pressed down, the tubular containers 4 with the help of the clamping surface of the slot 13 are moved and fixed relative to the plugs 14. The clamping element 12 has two diametrically located locking valves lever 1.5, one of which is shown in FIG. 3. For each locking lever 15, an axial slot 16 is provided in the clamping element 12 for guiding the flat part of the locking lever 15. As a pivot bearing for the locking ychaga.15 serves transverse pin 17. The locking lever 15 has two projections, one of which 18 fits into a slot 19 formed in the body of the hub, and the other 20 is yuschiys locking projection cooperates with a locking protrusion 11 the leading coupling element 9. The upper end 21 of the locking lever 15 is expanded, serves as a handle and moves along the element 22, made in the clamping element 12 and located above the slot 16. The return spring 23 encloses the hub and with one end rests on the rotor plate 2, Other end its spring 23 adjoins the spring plate 24, which is installed inside the recess 25 of the clamping element 12 and "presses the tab 18 on the locking lever 15. In the rotor plate 2 is pierced, there is no hole 26 for passing the locking tab 20 of the lever 15 to the working position.
    The device works as follows.
    Before commissioning, the dish-shaped rotor 2 is lowered onto the drive shaft 1 so that the coupling teeth 10 engage with connecting slots 6 (FIG. 4). Four tubular containers 4 are inserted into the rotor plate 2 and the splines 13 from the clamping element 12. The clamping element 12 is moved downwards. The tubular containers 4 with the help of the slot 13 are moved and fixed in the plate in relation to the plugs 14, and the locking protrusion 2: 0, the lever 15, after passing through the opening 26 under the influence of the spring 23, is fixed by the vortex 11 of the driving element 9 of the coupling (Fig. 5). The rotor plate 2 is thus engaged with the drive shaft 1.
    After the centrifuging operation, in which parts of the device rotate, for example, at high speed for several minutes, the operator presses the locking levers 15 so that both levers 15 make a pivotal movement relative to the pin 17. Disengagement occurs from the engagement of the locking protrusion 20 and the locking the protrusion 11. Under the influence of the spring 23, the clamping element 12 moves upwards and is set to its original position. Pipe-tank 4 s
    5, centrifuged contents are removed from the disk rotor 2.
    To extract the rotor plate 2 from the device in order to produce the cleaning of the radial receiving grooves 3
    0 and adjacent parts, gripping the clamping element 12 and the rotor plate 2 upwards from the position according to FIG. 4, until the rotor elements reach the release
    5 according to FIG. 3
    The invention improves the usability of the device due to the rapid replacement of the rotor plate.
