Description

В предлагаемом изобретении, касающемс  пипеток, действующих посредством нагнетани  воздуха в сосуд, содержащий набираемую жидкость, трубка, через которую нагнетаетс  воздух, помещена внутрь другой, забирающей жидкость трубки и имеет с последней общий кран.In the present invention, the pipettes acting by injecting air into the vessel containing the fluid to be drawn, the tube through which the air is injected, are placed inside another tube that receives the liquid and has a common tap with the latter.

Изображенна  на схематическом чертеже пипетка имеет следующее устройство .The pipette shown in the schematic drawing has the following device.

Внутрь трубки 1, имеющей боковое отверстие 5, впа на трубка 2, рааветвд юща с  у нижнего конца пипетки и оканчивающа с  отверсти ми 3, 3. Кран 4 с двум  каналами 7 и 8 служит дл  одновременного открывани  или закрывани  обеих трубок 1, 2. Каучукова  шайба 6, укрепленна  на нижней части пипетки, имеет назначение герметически закрыват| отверстие сосуда, ив которого набираетс  жидкость.Inside the tube 1, which has a lateral opening 5, is inserted into the tube 2, the hole at the lower end of the pipette and terminates at the openings 3, 3. The valve 4 with two channels 7 and 8 serves to simultaneously open or close both tubes 1, 2. The rubber washer 6, reinforced on the bottom of the pipette, has the purpose of hermetically closing | the opening of the vessel, in which fluid is drawn.

Опустив пипетку в сосуд так, чтобы отверсти  3,3 оказались над поверхностьюPutting the pipette into the vessel so that the holes 3,3 are above the surface

жидкости и в последнюю вошел лишь конец пипетки, плотно зажимают горлышко сосуда шайбой 6 и вдувают по трубке 2 воздух, под давлением которого жидкость поднимаетс  из сосуда и заполн ет резервуар трубки 1, по наполнени  которого закрь вают кран 4 и вынимают пипетку.liquids and only the end of the pipette entered the latter, tightly clamping the neck of the vessel with a washer 6 and blowing through the tube 2 air, under pressure of which the liquid rises from the vessel and fills the reservoir of the tube 1, filling the valve 4 and removing the pipette.

Предмет патента.The subject of the patent.

Пипетка, снабженна  двум  трубками- одной дл  нагнетани  воздуха в сосуд с жидкостью и другой, служащей дл  вмещени  набираемой пробы, отличающа с  тем, что дл  нагнетани  воздух в сосуд она снабжена впа нной внутренней трубкой 2, разветвл ющейс  у нижнего конца пипетки и оканчивающейс  отверстием 3,3/ а дл  сообщени  с атмосферой пнпвткн и сосуда с жидкостью применен кран 4 с каналами 7, 8 и отверстие 5 в верхней части пипетки.A pipette equipped with two tubes, one for injecting air into a vessel with liquid and another for accommodating the sample being collected, characterized in that for injecting air into the vessel it is provided with a hollow inner tube 2 branching at the lower end of the pipette and ending with an end 3.3 / a, valve 4 with channels 7, 8 and hole 5 in the upper part of the pipette were used to communicate with the atmosphere of the tank and the vessel with the liquid.
