Description
Technical field
The utility model is related to a kind of laboratory equipment more particularly to a kind of molding pipettes of biaxial tension.
Background technology
At present, pipette is the measuring device for accurately pipetting certain volume solution, is that one kind measures formula instrument, is only used for surveying
Measure the volume that it releases solution.Existing fat tripe pipette and straight trip pipette two types, fat tripe pipette is one elongated
And the intermediate glass tube expanded, there is an annular graticule in the upper end of pipe, enlargement indicates temperature during its volume and calibration.
Common fat tripe pipette has 10mL, 25mL, 50mL, 100mL equal-specification；Straight trip pipette is called graduated pipette, is to carry
Reticule measures formula weight device, for measuring the solution for pipetting on-fixed amount, often there is 1mL, 2mL, 5mL, 10mL, 25mL and 50mL
Wait different sizes.
It is all physics, chemistry and biology laboratory experimental implementation the most universal to measure liquid relief.In chemistry, biology,
In the experimentations such as medical test, it is often required to accurately metering and pipettes a series of solution that volumes change according to certain rules, such as volume
For a series of solution of 10mL, 25mL, 50mL, 75mL, 100mL, the graduated pipette that a volume is 100mL can be selected, it can
To pipette a series of solution of the volume as stereomutations of 10mL, 25mL, 50mL, 75mL, 100mL, so as to save many realities
Test the time.Pipette often coordinates ear washing bulb to be used together, and the transfer work of liquid is carried out using the mode of ear washing bulb air-breathing.
But there are following defects for existing pipette：
(1) pipette of the prior art be glassware, and it is repeated multiple times use, every time draw different liquids
Sample uses the preceding consuming that must all clean rinse, cause unnecessary time and manpower.And the tip of glassware is more crisp
Weak, easy fracture causes the inaccuracy of pipette volume, influences the accuracy tested.Pipette does not wash clean clearly easily, can cause
The cross contamination of sample room.
(2) pipette manufacturing process of the prior art is separately manufactured using tube head and tube body, and then ultrasound assembles again
Technology easily causes tube body and is asymmetrically formed defect ware or tube body and tube head assembly defect with tube head assembling, it is impossible to it uses, after
The problems such as tube body is plugged.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of molding liquid reliefs of biaxial tension
Pipe.For the application by the way that one is set to squeeze out pipette tube body, tube head and the imbibition tip of drawing and forming, material is polyphenyl second
Alkene, has higher hardness, and water white transparency, it is possible to prevente effectively from the fracture of imbibition tip and caused by pipette scrap,
And can clear and definite observe shifted sample.And the application is the integral extrusion used, then biaxial tension molding making
Instrument, can successfully reduce the inferior rate of product.
The purpose of this utility model adopts the following technical scheme that realization：A kind of molding pipette of biaxial tension, including moving
Liquid pipe tube body, the tube head for being connected to pipette tube body upper end and the imbibition tip for being connected to pipette bottom of the pipe；The shifting
Liquid pipe tube body stretches along tube body axial direction through polystyrene extrusion molding, the both ends of the pipette tube body and corresponds to shape respectively
Into tube head and imbibition tip.
Further, the pipette tube body is hollow pipeline, cylindrical.
Further, the pipette tube body top is equipped with the color for being used for that different volumes pipette to be distinguished using different colours
Ring.
Further, the pipette tubular body is plugged with the filter core with filtering iris action at tube head.
Further, the pipette tube body is equipped with to mark the scale for drawing volume of fluid.
Further, the tube head is cylindrical, and the caliber of tube head is less than the caliber of the pipette tube body.
Compared with prior art, the beneficial effects of the utility model are：
For the application by the way that one is set to squeeze out pipette tube body, tube head and the imbibition tip of drawing and forming, material is poly-
Styrene, has higher hardness, and water white transparency, it is possible to prevente effectively from the fracture of imbibition tip and caused by pipette report
It is useless, and can clear and definite observe shifted sample.And the application is the integral extrusion used, then biaxial tension molding is made
The instrument of work can successfully reduce the inferior rate of product.
Description of the drawings
Fig. 1 is the structure diagram of the molding pipette of the utility model preferred embodiment biaxial tension；
In figure：1st, pipette tube body；2nd, tube head；3rd, imbibition tip；4th, filter core.
Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1, a kind of molding pipette of biaxial tension, including pipette tube body 1, is connected on pipette tube body
The tube head 2 at end and the imbibition tip 3 for being connected to pipette bottom of the pipe；Pipette tube body is moved through polystyrene extrusion molding
The both ends of liquid pipe tube body stretch along tube body axial direction and are correspondingly formed tube head and imbibition tip respectively.
The molding pipette of biaxial tension of the application is the instrument of disposable integral extrusion, and material is polyphenyl second
