Abstract
The utility model proposes a kind of capillary drip nozzle, described capillary drip nozzle is provided with a hollow cavity, described capillary drip nozzle also comprises connecting portion, convergent part and drip nozzle portion, described connecting portion is provided with anti-slop serrations, described convergent part is funnel-form, described drip nozzle portion is the tubulose of diameter 0.1-0.6mm, and described connecting portion, convergent part and drip nozzle portion are one-body molded.
Description
Technical field
The utility model relates to miniature inorganic and Experiment of Analytical Chemistry equipment, refers to especially a kind of capillary drip nozzle.
Background technology
In existing titration experiments process, because buret drop is larger, easily produce reagent and use excessive or foot phenomenon not, the inaccuracy of reagent dosage, cannot avoid causing experiment fees to increase and the waste of funds, cause what is more the pollution to environment, can not meet both at home and abroad and carry out energetically and universal Green Chemistry, " microscale laboratory " needs.
Yet high-precision experiment equipment is high to processing technology requirement, difficulty large, expense is also very high.Once and high accuracy equipment damages to some extent, change its expense also very large.
For this reason, provide a processing cost capillary drip nozzle low, that can reach " microscale laboratory " requirement of experiment to necessitate.
Utility model content
The utility model proposes a kind of capillary drip nozzle, solved in miniature inorganic and Experiment of Analytical Chemistry process, easily cause the excessive or problem of foot phenomenon not of medicine.
The technical solution of the utility model is achieved in that a kind of capillary drip nozzle, described capillary drip nozzle is provided with a hollow cavity, described capillary drip nozzle also comprises connecting portion, convergent part and drip nozzle portion, described connecting portion is provided with anti-slop serrations, described convergent part is funnel-form, and described drip nozzle portion is the tubulose of diameter 0.1-0.6mm.
Described connecting portion, convergent part and drip nozzle portion are one-body molded.
Further, described anti-slop serrations is located at the top of connecting portion, and it is round and smooth contraction-like that the hollow cavity inwall on described connecting portion top is that smooth wall and inwall are.
Further, described drip nozzle portion diameter is 0.28-0.45mm.
Further, described drip nozzle minister 1-10cm.
Compared with prior art, a kind of capillary drip nozzle that the utility model provides, it includes connecting portion, together with this connecting portion is used for being connected to existing buret, the inwall of hollow cavity is provided with smooth wall, and this smooth wall is conducive to the good combination of the utility model and buret.Contraction-like structure is for to be dwindled gradually to drip nozzle portion by connecting portion, when connecting portion is connected with buret, can match with buret better, make buret bottom can be nested in connecting portion, and connecting portion is tied together mutually with buret bottom, reaches good seal and connect.
The length of drip nozzle portion and thickness can be controlled the flow of fluid well, by drip nozzle portion internal diameter is made as to 0.1-0.6mm, can droplet size is accurate to 0.004-0.005ml, be that 1ml drop 200-250 drips, greatly improve the precision of reagent in miniature inorganic and Experiment of Analytical Chemistry process, avoid conventional titration to test in the excessive or not enough situation of reagent used, generation unreacting reagent residue, and the major part of these residue reagent is introduced into sewer, by running water, washed away, and these reagent major parts are poisonous, there is pollution, use the experiment of capillary drip nozzle, the consumption of reagent only has 1/10th of normal experiment reagent dosage, can save reagent dosage, reduce or avoid environmental pollution, there is significant economic benefit and environmental benefit.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of a kind of capillary drip nozzle that Fig. 1 provides for the utility model.
Fig. 2 is that capillary drip nozzle is used status architecture schematic diagram.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of capillary drip nozzle 100 that the utility model provides, described capillary drip nozzle 100 is provided with a hollow cavity 12, described capillary drip nozzle 100 also comprises connecting portion 1, convergent part 2 and drip nozzle portion 3, described connecting portion 1 is provided with anti-slop serrations 11, described convergent part 2 is funnel-form, and described drip nozzle portion is the tubulose of diameter 0.1-0.6mm, and described connecting portion 1, convergent part 2 and drip nozzle portion 3 are one-body molded.The capillary drip nozzle that the utility model provides is simple in structure, but from having solved in fact well miniature inorganic and Experiment of Analytical Chemistry, requirement to high accuracy experiment process equipment, its cost is very low, and coordinate existing laboratory apparatus to use, greatly save the cost of addition instrument, removed the process issues of high accuracy processing test tube from.
Described anti-slop serrations 11 is located at the top of connecting portion 1, and it is round and smooth contraction-like that hollow cavity 12 inwalls on described connecting portion 1 top are that smooth wall and inwall are.The utility model is by anti-slop serrations 11 and smooth hollow cavity inwall, make the utility model more tight with being connected of test tube, can not produce leakage phenomenon, as better embodiment, inwall is made as contraction-like, make to the utlity model has connect different test tubes compared with strong adaptability.
Described drip nozzle portion is diameter 0.28-0.45mm.The described drip nozzle 3 long 1-10cm of portion.
A kind of capillary drip nozzle 100 that the utility model provides, it includes connecting portion 1, this connecting portion 1 is for being connected with existing buret, the inwall of the hollow cavity 12 at connecting portion 1 place is provided with smooth wall, this smooth wall is conducive to the good combination of the utility model and buret, convergent part 2 structures are dwindled gradually, can adapt to different model buret, when connecting portion 1 is connected with buret, obturation effect is good, buret bottom can be nested in connecting portion 1, and connecting portion 1 is tied together mutually with buret bottom.A kind of preferred version during as use, first by after the gas discharging of buret bottom, connect again capillary drip nozzle 100, the length of drip nozzle portion and thickness can be controlled flow well, by drip nozzle portion internal diameter is made as to footpath 0.1-0.6mm, preferably drip nozzle portion is diameter 0.28-0.45mm, can droplet size is accurate to 0.004-0.005ml, be that 1ml drop 200-250 drips, greatly improve the precision of miniature inorganic and Experiment of Analytical Chemistry.In use generally first get rid of the air of buret bottom, the circulation status of fluid can be controlled by buret switch.
