Detailed Description
The following detailed description of the embodiments of the present invention is provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to clearly and clearly define the scope of the present invention.
Example 1
Referring to fig. 1-5, the quantitative liquid taking tube comprises a funnel part 1 and a test tube part 2; it is characterized in that the lower end of the funnel part 1 is detachably connected with the upper end of the test tube part 2; the side wall of the test tube part 2 is provided with scale marks 5; the volume value corresponding to the scale line 5 is the volume of the test tube part 2 below the scale line 5; the funnel part 1 and the test tube part 2 are both made of flexible transparent materials.
Description of the methods and principles of use: because the invention adopts flexible transparent material, the tabletting treatment can be carried out during the packaging so as to save the packaging space; the operator needs to unfold the tablet pressing state of the invention into a using state in the first step; then an operator pinches the lower end of the funnel part 1 by fingers of one hand, and the upper end of the separable part of the funnel part 1 and the test tube part 2 is positioned; then operating a beaker or other container with the other hand to pour a first portion of the solution into the funnel, wherein the volume of the poured solution is larger than the volume of the required solution; then slightly loosening the fingers at the lower end of the funnel part 1 to enable the first solution to flow into the test tube part 2, controlling the speed of the first solution flowing into the test tube part 2 by controlling the loosening degree of the fingers in the process, accelerating the flowing speed of the solution by a method of flicking the test tube part 2 by the fingers for the solution with larger viscosity, and when the volume of the first solution flowing into the test tube part 2 reaches a designated scale mark 5, pinching the lower end of the funnel part 1 again to separate the funnel part 1 from the test tube part 2, namely finishing quantitative liquid taking of the first solution; then other reagents are added into the first solution after quantification through the opening at the upper end of the test tube part 2 and are mixed uniformly, so that the subsequent chemical experiment or detection is completed.
The flexible transparent material is one of PC, PE, PVC, flexible glass fiber, rubber, plastic and resin.
The side wall of the joint of the lower end of the funnel part 1 and the upper end of the test tube part 2 is provided with first blind hole type breakpoints 31 which are uniformly distributed; the first blind hole type breakpoints 31 distributed uniformly form the first separation line 3.
Thus, the first blind hole type breakpoint 31 does not penetrate through the side wall of the joint of the lower end of the funnel part 1 and the test tube part 2; so that the solution does not flow out through the first blind-hole break point 31; when separating funnel portion 1 and test tube portion 2, two hands respectively pinch the both sides of first branch line 3, can separate funnel portion 1 and test tube portion 2 in first branch line 3 department through the effect of shearing force.
When the volume of the first portion of solution flowing into the test tube part 2 reaches the predetermined scale line 5, the lower end of the funnel part 1 is pinched again, and the funnel part 1 is pulled out from the test tube part 2 to be separated.
The lower section of the test tube part 2 is sequentially provided with a contraction section 21 and a liquid outlet section 22 from top to bottom; the cross section of the contraction section 21 is gradually reduced; the side wall of the liquid outlet section 22 is provided with second blind hole type breakpoints 41 which are uniformly distributed; the second blind hole type breakpoints 41 distributed uniformly form a second separation line 4.
Thus, since the second blind-hole breakpoint 41 does not penetrate the side wall of the tapping section 22; so that the solution does not flow out through the second blind hole break point 41; after other reagents are added into the quantified first solution through the opening at the upper end of the test tube part 2 and are uniformly mixed, the upper section of the liquid outlet section 22 of the test tube part 2 and the lower section of the liquid outlet section 22 can be separated at the second separation line 4; when the upper section of the liquid outlet section 22 and the lower section of the liquid outlet section 22 are separated at the second separation line 4, the two hands respectively pinch the two sides of the second separation line 4, namely the upper section of the liquid outlet section 22 and the lower section of the liquid outlet section 22 can be separated at the second separation line 4 under the action of shearing force, so that the lower end of the upper section of the liquid outlet section forms an opening; then the mixed solution in the test tube part 2 is added into an experimental instrument or an analytical instrument through an opening at the lower end of the upper section of the liquid outlet section 22 so as to complete subsequent chemical experiments or detection, so that the use of the invention is more convenient.
Example 2
Referring to fig. 6, a quantitative liquid take-off tube, embodiment 2 and embodiment 1 are different in that the second separation line 4 is obliquely disposed.
This helps the mixed solution to closely adhere to the inner wall of the container when flowing out through the opening at the lower end of the upper section of the liquid outlet section 22. .
Example 3
Referring to FIGS. 7 to 8, a quantitative liquid taking tube, embodiment 3 is different from embodiment 1 in that the outer side wall of the lower end of the funnel part 1 is fitted with the inner side wall of the upper end of the test tube part 2; the lower end of the funnel part 1 is inserted into the upper end of the test tube part 2.
Since the lower end of the funnel part 1 is inserted into the upper end of the test tube part 2, the lower end of the funnel part 1 and the upper end of the test tube part 2 have a gap between the outer side wall of the lower end of the funnel part 1 and the inner side wall of the upper end of the test tube part 2 due to the flexibility of the material, which is helpful for the solution to flow downwards.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
