Abstract
The utility model discloses a weighing titration bottle, comprising a soft plastic bottle body and a capillary burette which is arranged at the upper part of the soft plastic bottle body in an outwards convex way. The capillary burette is communicated with the inner chamber of the bottle. The weighing titration bottle has simple structure, small volume, light weight, easy manufacturing, convenient transportation, movement and weighing, low requirement on a balance and low cost, is not easy to be damaged; and the titration of the solution is controlled through extruding the bottle body or the bottle bottom, therefore, the weighing titration bottle has simple and convenient operation and favorable application prospect.
Description
Technical field
The utility model relates to a kind of titration bottle, particularly a kind of weighing titration bottle.
Background technology
State Standard of the People's Republic of China GB 10738-2007 working standard reagent assay general rule gravimetric titration method has been stipulated the quality with analytical balance weighing working solution or reference solution, determine the titrimetry method of terminal point with indicator method, mainly may further comprise the steps: 1. standard substance or the sample that weighs up placed reaction bulb, add indicator solution; 2. working solution or reference solution are placed dry weighing titration bottle, weighing; 3. connect weighing titration apparatus (comprising weighing titration bottle, reaction bulb, magnetic stirrer and two bulb), start magnetic stirrer, carry out titration, drip to terminal, take off the weighing titration bottle, weighing.The difference of twice weighing is the working solution that consumed or the quality of reference solution.
There are the following problems for wherein employed weighing titration bottle: 1. complex structure, and volume is big, weighing inconvenience; Employing glass material preparation, Heavy Weight has higher requirements the cost height to the sensibility reciprocal and the maximum capacity of balance; Glass apparatus damages easily, transportation and move inconveniently, and different parts connector must adopt frosted, note maintenance constantly; 2. carry out titration by piston control solution, operation is convenient inadequately.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of weighing titration bottle, and simple in structure, volume is little, and is in light weight, easy to manufacture, not fragile, transportation, mobile and weighing convenience, and low to the balance requirement, cost is low, and is simple to operate.
For reaching this purpose, the utility model adopts following technical scheme:
The weighing titration bottle comprises the flexible plastic bottle and outwards protrudes the capillary burette that is arranged on flexible plastic bottle top that described capillary burette communicates with the bottle inner chamber.
This weighing titration bottle has two kinds of exemplary embodiment: a kind of is that described flexible plastic bottle and capillary burette are made as one; Another kind is also to comprise bottle cap, and described bottle cap is arranged on the top of flexible plastic bottle removably, and the capillary burette of outside protrusion is set on the bottle cap.
Further, described weighing titration bottle also comprises the dropper cap, and described dropper cap is enclosed within the endpiece of capillary burette removably.
Further, described weighing titration bottle also comprises connection chain, and an end of described connection chain is connected with the dropper cap, and the other end is arranged on flexible plastic bottle, bottle cap or the capillary burette removably.
Further, described flexible plastic bottle is flat.
The beneficial effects of the utility model are: the weighing titration bottle that is provided, and simple in structure, volume is little, and is in light weight, easy to manufacture, not fragile, transportation, mobile and weighing convenience, low to the balance requirement, cost is low; Carry out titration by extruding body or bottle end control solution, simple to operation, application prospect is good.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is first kind of embodiment structural representation of weighing titration bottle;
Fig. 2 is second kind of embodiment structural representation of weighing titration bottle.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of first kind of embodiment of weighing titration bottle, and as shown in the figure, the weighing titration bottle comprises flexible plastic bottle 1 and the capillary burette 2 that is arranged on flexible plastic bottle 1 top protruding upward, and capillary burette 2 communicates with the bottle inner chamber; Adopt preparation bottles such as flexible plastic such as teflon, tygon, in light weight, low to the balance requirement, and can carry out titration by extruding body or the interior solution of bottle end control bottle, simple to operation; Certainly, capillary burette 2 also can outwards protrude the top, side that is arranged on flexible plastic bottle 1 except the top that is arranged on flexible plastic bottle 1 protruding upward, can reach the purpose of this utility model.
In the present embodiment, flexible plastic bottle 1 and capillary burette 2 are made as one, and simple in structure, cost is low, and solution can be sucked in the bottle by capillary burette by the extruding body or the bottle end, extruded with the same manner and carried out titration.
The weighing titration bottle of present embodiment also comprises dropper cap 3, and dropper cap 3 is enclosed within the endpiece of capillary burette removably; Adopt the outlet of pipe cap sealing capillary burette, can avoid a bottle interior solution evaporation or contaminated.
In order to prevent that the dropper cap from losing or contaminated, the weighing titration bottle of present embodiment also comprises connection chain 4, and an end of connection chain 4 is connected with dropper cap 3, and the other end is arranged on the capillary burette 2 removably.Certainly, the other end of connection chain 4 on being arranged on capillary burette 2, also can be arranged on the flexible plastic bottle 1, can reach the purpose of this utility model.Connection chain 4 adopts dismountable mode to be provided with, and can avoid the influence of dropper cap to titration operation.
In the present embodiment, flexible plastic bottle 1 is flat, can be placed on easily to carry out weighing in the scale pan.
Embodiment 2
Fig. 2 is the structural representation of second kind of embodiment of weighing titration bottle, be with embodiment one difference: the weighing titration bottle of present embodiment also comprises bottle cap 5, described bottle cap 5 is arranged on the top of flexible plastic bottle 1 removably, and the top of bottle cap 5 is provided with capillary burette protruding upward 2; Adopt this kind structure, the bigger bottleneck of bore can be set on the top of flexible plastic bottle, in bottle, add solution quickly and easily thereby be beneficial to.Certainly, capillary burette 2 also can outwards protrude the side that is arranged on bottle cap 5 except the top that is arranged on bottle cap 5 protruding upward; The other end of connection chain 4 on being arranged on capillary burette 2 or flexible plastic bottle 1, also can be arranged on the bottle cap 5, can reach the purpose of this utility model.
In addition, multiple shapes such as that flexible plastic bottle of the present utility model can be made into is cylindrical, taper shape or pyriform, volume can be little to several milliliters or arrive hundreds of milliliters greatly, can realize the utility model purpose, and can come the amount of oozing of controlling liquid by the caliber of change capillary burette.
