Embodiment Construction

[0018] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0019] as attached figure 1 The shown disposable pipette tip includes a tip body consisting of a suction nozzle area 11, a quantitative liquid storage area 12, an empty area 14, and a pipette gun action area 13 from bottom to top, and the inner diameter of the tip body is from bottom to top Gradually increasing; the lower part of the vacant area 14 is provided with a lower supporting ring 141, the upper part is provided with an upper resisting ring 142, and a filter element 15 is arranged in between. There is a vacant section 143 between the upper resistance ring 142 and the second encryption ring 132, which can stabilize and fix the filter core, and make the mouth end of the pipette gun not tightly against the filter core, so as to ensure the smooth absorption of the liquid. The lower inner surface of the pipette gun action area 13 is pro...

Abstract

The invention belongs to the field of experimental apparatuses, and relates to a disposable pipette tip. The disposable pipette tip comprises a tip body, wherein the tip body comprises a suction nozzle area, a quantitative liquid storage area and a pipette active area from bottom to top, wherein a vacant area is arranged between the quantitative liquid storage area and the pipette active area, a filter element is arranged in the vacant area, a first seal ring and a second seal ring are vertically arranged on the inner surface of the lower part of the pipette active area, and the second seal ring is located on a junction surface of the pipette active area and the vacant area. The disposable pipette tip is good in sealing performance and accurate in liquid suction, a pipette can be inserted into the tip in a more labor-saving manner, and is convenient to dismount; and by means of the filter element, a liquid cannot be sucked into the pipette, and the filter element cannot influence results of smooth liquid suction and quantitative liquid suction.

Description

technical field [0001] The invention belongs to the field of experimental equipment, and relates to equipment for pipetting, in particular to a disposable pipette tip. Background technique [0002] Pipette tip is a kind of consumable that is widely used in medical, biological, chemical and other fields. It is used with pipette gun to quantitatively measure liquid. However, there are certain problems in the connection between the existing pipette tip and the pipette gun, for example: 1. The sealing is not good enough, liquid leakage occurs, and the accuracy is poor, which affects the experimental results; The gun is tightly locked, press the pipette head with your hand and press it hard or put the pipette into the pipette head, and stamp it hard, which will cause serious wear and tear of the pipette gun, and the former will also cause cross-contamination ; 3. When removing the pipette tip, it cannot be removed only by the thrust of the pipette gun. It needs to be pulled out ...
