    SP 1 The invention relates to a laboratory equipped MO, in particular to pipettes. A known pipette comprising a hollow cylindrical body with a cap, a spring-loaded piston mounted therein, a button with a rod for interacting with the piston, and means for restricting the movement of the piston. In this pipette, means for restricting the movement of the piston provide a shorter piston stroke during suction than during emptying, which allows the Cl3 pipette to be completely empty. However, these tools are quite complex, since they are sleeve elements that interact with the cam, and the worker must control the position of the piston. The purpose of the invention is to simplify the emptying of the pipette and improve ease of use. The goal is achieved by the fact that a pipette containing a hollow cylindrical body with a cap, a spring-loaded piston installed in it, a button with a rod for interacting with the piston, means for restricting the movement of the piston, is provided with an additional button with a rod mounted coaxially to the stem of the main button on the stem of buttons threaded rings are installed to fix the buttons in the upper position, while the means for limiting the movement of the piston are an emphasis on the core of the main button and two rings The outer collar, one of which is located on the top of the core, and the other, is located at the top of the stem of the additional button. FIG. 1 shows the proposed pipette, side view, partial cut in FIG. 2 - the same, top view; in fig. 3 - part of the pipette with partial incision. The pipette contains a hollow cylindrical body consisting of two tubular parts 1 and 2, interconnected by a threaded connection, and screwed onto part 1 of the clamp 3. In the cylindrical spaces of the body there is a movable piston which is pressed upwards by a spiral spring 5. The piston is compacted relatively cylinder ring seal 6, it can be squeezed. Down, pre 5 share the force of the coil spring, using the main button 7 and additional - 8. Rods 9 and 10, respectively, buttons 7 and 8 are located one inside the other with the possibility of axial movement relative to each other. The stem 10 of the button 8 provided with an external thread has threaded rings 11 and 12, between which the lock ring is so located that it is possible to fix these rings on the rod 10 of the button 8 in any position. Accordingly, at the lower end of the rod 9 of the inner button 7, two rings 13 and 14 are placed, which can be fixed by means of elements installed between them. The ring 11 touching the bottom of the cover 3 defines the height of the lift of the button 8, respectively the lower surface of the rod 10 of the button 8, the ring 13 determines the height of the lift of the button 7 above the button 8. The lower extreme positions of the buttons are determined by the annular shoulder 15 in conjunction with the ring shoulder 16 and step 17, respectively located on buttons 8 and 7. By adjusting the rings 11, 12, 13 and 14, the stroke length of the piston can be changed. The essence of the invention is to use one button (8) to fill the pipette and another button with a larger stroke to empty the pipette, while the piston 4, when emptying, passes further to the tip of the pipette than when it is filled, thus ensuring reliable emptying of the pipette. A pipette may have a larger number of fill buttons, providing variously large doses (portions) of the contents. The main thing is that the emptying button is designed so that it always provides the maximum height of the piston stroke. A pipette with one filling button and one emptying button is preferred, and the filling button can be adjusted in a known manner with a stepless or stepwise setting. The length of the stroke corresponding to the emptying button is always greater than the stroke of the filling button corresponding to the maximum charge (dose).

    In addition to the embodiment shown in the drawings, the rods may have, for example, a square cross section and slide along each other, a semicircular cross section, and they will then slide along each other with flat surfaces. The rods may finally move slightly apart from each other, being separated by a partition.
    The very shape of the buttons is determined in part by the arrangement of the rods, however, the ease of circulation also plays a role. In the embodiment shown in the drawings, the emptying button 7 is shaped in such a way that the button 7 accurately fits into the recess in the filling button 8 and is tightly closed with it in the depressed state or the outer blunt about 1 mm above the surface of the button 8.

    For convenience, it is advisable to equip the body of the pipette with a protrusion 18, on which the index finger is placed when pressing the button 7 or 8 5 with a thumb. The core button 8 is provided, for example, with four longitudinal ribs (not shown) preventing twisting relative to the cover 3 and allowing also to provide a certain desired position with respect to the protrusion 18.
    As is known, a round ring serves as a seal. If the pipette is to be completely sterilized, then the seal can be performed, for example, from fluoroplastic (Teflon) or other suitable material, as shown in FIG. 3
    20 The proposed design is easy to maintain and does not require monitoring the correctness of the piston stroke.
