Abstract
The utility model provides a novel pipette suction nozzle which belongs to medical or chemical analysis appliances. The novel suction nozzle is provided with a pipette with marks on the surface, wherein one end of a flexible pipe is communicated with the pipette; and the other end of the flexible pipe is communicated with a rubber ball. The novel pipette suction nozzle has a reasonable structure and can be used for conveniently and safely sucking, transferring and releasing liquid so as to complete the transfer of liquid. The novel pipette suction nozzle is precise in liquid addition volume, improves the testing accuracy and saves time and labor in operation.
Description
Technical field
The utility model provides a kind of medical or chemical analysis to use utensil, especially a kind of pipette suction nozzle.
Background technology
Pipette is widely used in and accurately pipettes various liquid.Existing pipette is a glass tube, and there is the volume scale on its surface.The negative pressure of leaning on ear washing bulb (being a ball) or artificial mouth to inhale during use to be produced is with in the liquid suction pipette.Must take another hand extruding ear washing bulb of pipette when adopting ear washing bulb on the other hand, remove ear washing bulb after treating in the liquid suction pipette, take the hand of pipette will vacate a finger at once the pipette flap is lived, in case the liquid of suction flows out complex operation once more.When adopting artificial mouth to inhale, exist the danger in the fluid intake.
Summary of the invention
The utility model technical problem to be solved is a kind of novel pipette suction nozzle to be provided, to improve the convenience that liquid pipettes.
The utility model is achieved in that a kind of novel pipette suction nozzle, and it has the pipette of surface band scale, flexible pipe one end and pipette is connected together, the other end and ball are connected together.
Adopt the pipette suction nozzle of said structure, rational in infrastructure, can aspirate, move and emit liquid easily and safely, accomplish pipetting of liquid.Liquid volume added is accurate, has improved test accuracy, and it is time saving and energy saving to operate.
Description of drawings
Fig. 1 is the sketch map of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
Shown in accompanying drawing, a kind of novel pipette suction nozzle of the utility model, it has the pipette 1 of surface band scale, flexible pipe 2 one ends and pipette is connected together, the other end and ball 3 are connected together.
Described flexible pipe can adopt rubber tube.The hardness and the rubber pipette bulb of ball are close, and the hardness of flexible pipe can be soft slightly.
During use, the other end that an end is communicated with at the flexible pipe on the ball is enclosed within on the pipette, loosens after the ball of holding with a firm grip again, can produce negative pressure, and liquid is sucked pipette, pushes ball once more and can the liquid that suck be discharged, thereby realize pipetting of liquid.
Obviously, the scale on pipette surface is the volume scale.
Claims (1)
1. a novel pipette suction nozzle is characterized in that, it has the pipette (1) of surface band scale, flexible pipe (2) one ends and pipette is connected together, the other end and ball (3) are connected together.
