Abstract
A multi-function liquid filling device is a sample solution filling apparatus used for analysis and detection. The device includes two or three hollow volume balls, which are communicated through communicating pipes. The pipe body on top of the first volume ball is equipped with three interfaces. A hole which communicates the interfaces with the first volume ball is arranged in the pipe body and under the interfaces mentioned above. A floater which can enclose the hole is arranged under the hole. The bottom of the last-position volume ball is equipped with a fluid absorption and discharge pipe, the bottom end of which is a liquid absorption and discharge mouth. The communicating pipe between the first volume ball and the second volume ball adjacent to the first volume ball is divided into two segments. The inner diameter of the upper segment communicating pipe, one end of which is directly connected with the first volume ball, is larger than the inner diameter of the lower segment communicating pipe, one end of which is directly connected with the adjacent volume ball mentioned above. One pipette is used to separate the solution with high and low content and multi-elements. And the speed of the solution separation is fast and the precision is high.

Technical field
The utility model relates to analysis and detection technology, specifically is meant a kind of utensil that adds sample solution.
Background technology
In the prior art, conventional calibrated pipet, whole pipette, micropipet, automatic pipet(te) all are simple functions.The patent No. be ZL01257379.5 the rapid multi-element analysis instrument in use, the solution (and requiring different imbibition precision) that will draw different capabilities from the sample solution of preparation develops the color in color-emitting cup, normally get liquid, waste time and energy with the suction pipe of many different performances; For getting the liquid accuracy requirement below 0.1% up to the element of 90% sample, have only with the big tripe pipettor of conventional 5-10ml and just can reach this precision, colour developing volume liquid requires 100-200ml, even will dilute the photometric analysis requirement that sample solution could satisfy high-load earlier.
The utility model content
The technical problems to be solved in the utility model is, the defective at prior art exists designs a kind of multi-functional charger, and it gets solution with the branch that a branched pipette can satisfy high and low content multielement simultaneously, and divides and get solution not only soon but also standard.
The technical solution of the utility model is, described multi-functional charger has the volume ball by two to three hollows that are communicated with successively communicating pipe, the body at the first volume ball top is provided with three interfaces, in described body and below being positioned at described interface, be provided with a through hole that is communicated with the described interface and the first volume ball, be provided with the float of this through hole of sealing below this through hole, the bottom of position, end volume ball is provided with bottom end for inhaling the suction discharging tube of apocenosis mouth; Be divided into two sections communicating pipe between the first volume ball and the adjacent with it volume ball, wherein the end internal diameter that directly connects the epimere communicating pipe of the first volume ball directly connects the internal diameter of the hypomere communicating pipe of described adjacent volume ball greater than an end.
Below the utility model made further specify.
Referring to Fig. 1, the utility model has the volume ball by two to three hollows that are communicated with successively communicating pipe, the body 8 at the first volume ball, 5 tops is provided with three interfaces 1,2,3, in described body 8 and below being positioned at described interface, be provided with a through hole that is communicated with the described interface and the first volume ball 1, be provided with a float 4 that can seal this through hole below this through hole, the bottom of position, end volume ball 7 is provided with bottom end for inhaling the suction discharging tube 9 of apocenosis mouth; Be divided into two sections communicating pipe between the first volume ball 5 and the adjacent with it second volume ball 6, wherein the end internal diameter that directly connects the epimere communicating pipe 10 of the first volume ball 5 directly connects the internal diameter of the hypomere communicating pipe 11 of described adjacent volume ball 6 greater than an end.
When the volume ball of the utility model setting was three, they were the first volume ball 1, the second volume ball 6, position, end volume ball 7 shown in Figure 1; When the volume ball that is provided with was two, then the second volume ball 6 was same volume ball with position, end volume ball 7.
During actual the use, can be as shown in Figure 1, connect 1 and the 10ml syringe with conduit, be connected Φ 0.5mm and Φ 0.01 air admission hole with interface 2 and interface 3 are corresponding respectively with two conduits, and two air admission holes seal with valve respectively.Using method can be:
1, rises to float 4 with 10ml syringe quick imbibition and stop feed liquor automatically; Promote the whole liquid of this syringe fast evacuation again; This process is only done and is measured low content Fe, Ti usefulness;
2, again with the quick feed liquor of syringe, open the valve of interface 2, with conventional flow velocity liquid feeding 3ml, 1ml, 1ml, for measuring Si, Ca, Mg usefulness;
3, down interface 2, open interface 1, and the flow velocity that slows down is convenient to accurately locate the scale of 1ml, 0.5ml volume ball, accurately liquid feeding 1ml, 0.5ml, and the liquid feeding error is less than 0.1%.So just satisfied the requirement of heavy contend analysis, and needn't also needn't make things convenient for next step adding chromogenic reagent and liquid feeding automatically automatically earlier with the test solution dilution with jumbo volumetric flask colour developing;
4, inhale solution to 2ml scale place, open the valve of interface 2, just can be by dripping the number liquid feeding, because air admission hole unanimity, liquid level unanimity, the test solution density, the viscosity that add preparation are all consistent, atmospheric pressure changes very small and can ignore at same operation room, suction pipe position is fixed again, the repetitive error that adds 4 test solutions (about 0.2ml) continuously is less than 0.5%, this just can accomplish to gather and seldom measure the photometric analysis that test solution carries out high content component, do not need the large volume colour developing, both significantly saved the time, saved reagent again greatly.
The utility model can be used syringe and float 4 quick feed liquor and the discharge opeings that are connected with interface 1; The usable interface 2 and the first volume ball 5 carry out conventional flow velocity discharge opeing, reach the precision of whole pipette, are not very high photometric analysiss for accuracy requirement; Usable interface 3 and volume ball 6,7 carry out exact scale location and control liquid speed, guarantee small size, high precision discharge opeing, use for the high precision photometric analysis.Volume ball 6,7 available internal diameter are the frosted glass pipe blowing of 0.3-0.5mm, cooperate with interface 3 to make things convenient for, accurately to locate volume ball scale, make positioning error less than 0.1%; Interface 3 control flow velocitys, make evacuation of liquid after, the repetitive error of volume ball 6,7 adhering liquids is less than 0.1%.
As known from the above, the utility model is a kind of multi-functional charger, and it gets solution with the branch that a branched pipette can satisfy high and low content multielement simultaneously, and branch is got, and solution speed is fast, precision is high.
