Abstract
The utility model relates to the field of experimental facilities and particularly relates to a burette. Aiming to solve the technical problems, the utility model provides the burette capable of accurately titrating a lot of liquid. According to the adopted technical scheme, the burette comprises a pipe body, wherein the pipe body is internally provided with a pipe cavity; the pipe cavity is communicated with the outside by a pipe opening; the pipe cavity comprises a titration cavity and a liquid metering cavity; the liquid metering cavity is internally provided with a piston head; the piston head is driven by a piston push rod; the piston head is clung to the wall of the liquid metering cavity; the flowing-out end and the liquid metering end of the pipe body are provided with scales. By additionally arranging the liquid metering cavity, the flowing-out end and the liquid metering end of the pipe body are provided with the scales, so that the effect of dripping out the liquid in the pipe by pushing the piston push rod to drive the piston head in the titration process can be realized. When the liquid is dripped out, the amount can be accurately controlled by referring the scales on the flowing-out end and the liquid metering end of the pipe body. The utility model can be applied to the burette capable of titrating a lot of the liquid.
Description
Technical field
The utility model relates to experimental facilities field, especially a kind of buret.
Background technology
Traditional buret, owing to can only control by carry out affectedly shy firmly titration air bag with hand the speed of dropping liquid in titration process.Oozing certain dripping after number, user not only can be difficult to because of hand soreness control accurately titration air bag again and realize titration liquid in pipe is oozed accurately, in addition, because the gas of air bag is now extruded substantially, also no longer can well control dropping liquid.Therefore, traditional buret is only applicable to the liquid of instillation small amount, once after the instillation time grown, can bring larger error.
Utility model content
Technical problem to be solved in the utility model is to provide the buret of the relatively large liquid of the accurate titration of a kind of energy.
The utility model solves the technical scheme that its technical matters adopts: buret, comprise body, in body, be provided with tube chamber, described tube chamber communicates with the external world by the mouth of pipe, tube chamber comprises titration chamber and amount sap cavity, in amount sap cavity, be provided with piston head, described piston head drives by piston push rod and the chamber wall of piston head and amount sap cavity is close to, and on the outflow end of body and amount liquid end, is provided with scale.
Further: titration chamber consists of the titration air bag being arranged on body.
The beneficial effects of the utility model are: by the amount of setting up sap cavity, and be provided with scale on the outflow end of body and amount liquid end, can realize the effect by promoting piston push rod driven plunger head, liquid in pipe being oozed in titration process, and described oozing can realize control very accurately.When oozing, can accurately control with reference to the scale on the outflow end of body and amount liquid end.The utility model can be applied in the buret of the relatively large liquid of titration.
Accompanying drawing explanation
Fig. 1 is cut-open view of the present utility model.
Fig. 2 is schematic diagram of the present utility model.
In figure, be labeled as: body 1, tube chamber 11, amount sap cavity 111, titration chamber 112, outflow end 12, amount liquid end 13, the mouth of pipe 14, piston push rod 2, piston head 21.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Buret as shown in Figure 1 and Figure 2, comprise body 1, in body 1, be provided with tube chamber 11, described tube chamber 11 communicates with the external world by the mouth of pipe 14, tube chamber 11 comprises titration chamber 112 and amount sap cavity 111, in amount sap cavity 111, be provided with piston head 21, described piston head 21 drives by piston push rod 2 and piston head 21 is close to amount sap cavity 111 chamber walls, on the outflow end 12 of body 1 and amount liquid end 13, is provided with scale.
As shown in Figure 1, the piston head 21 in amount sap cavity 111 is the assurance that realizes titration with the scale being arranged on outflow end 12 and amount liquid end 13, only needs careful promotion piston push rod 2 during use.When making the utility model, first-selected transparent material is made body 1, and the mark of scale in use can be shrewd.It is the accuracy while guaranteeing to ooze drop that piston head 21 and amount sap cavity 111 chamber walls are close to.
The improvement of such scheme the most, can select such scheme: titration chamber 112 consists of the titration air bag being arranged on body 1.Titration air bag is the use for fitting piston head 21 dropping liquids, allows the utility model not only can realize titration by promoting piston head 21, also can realize titration by titration air bag, for user provides the titration mode of diversification.
