Abstract
The utility model provides a microburet, comprising a micro titration device and a liquid receiver; wherein, the micro titration device is cylindrical body with scales on the body and a piston switch is arranged at the lower end of the micro titration device; and an oval funnel higher than the upper port of the micro titration device is arranged at the upper end of the liquid receiver and a piston switch is arranged at the lower end of the liquid receiver, thus standard solution can be directly introduced into the micro titration device. The body of the microburet is designed smaller than the body of general burettes. The microburet can be used in micro titration, which has the characteristic of convenient, rapid, accurate and continuous titration. The utility model has the advantages of simple operation, favorable application effect, low manufacturing cost and convenience in popularization.
Description
Technical field
The utility model relates to sample analysis instrument field, is specifically related to a kind of microburet.
Background technology
Buret is to be used for the instrument that conventional chemical is analyzed, titrimetry is mainly used in measures the more material of content, its principle is exactly to utilize the quantitative reaction between the chemical substance to analyze, mainly contain acid base titration, complexometry, precipitation titration and redox titration etc., also have the titration of some constant-current titrations and non-aqueous system also to use buret.Generally speaking, the material that uses buret to analyze, the volumetric soiutions that titration consumes all will surpass 10ML, so just can make the titrimetry error less, and the result is more accurate.Yet, in actual analysis work, run into the low sample of many content usually, in the titrimetry process, only consume the titrating solution of 3-5ML, if use common buret to carry out titrimetry, will produce bigger error, impact analysis result's accuracy, therefore these samples are not suitable for carrying out titrimetry with common buret, if use microburet to measure, just can reduce error, improve the degree of accuracy.Do not see at present the buret report that is used for micro-analysis.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide a kind of microburet, is used to analyze the less sample of content, easily and fast, the content of titration material exactly.
For achieving the above object, the utility model adopts following technical scheme:
A kind of microburet, described microburet are to be made of micro titrator 1 and liquid reservoir 2.
Above-mentioned micro titrator 1 is a cylinder, be used to contain the standard liquid that titration is used, have scale 11 on the pipe shaft, the standard liquid volume that the index titration consumes, there is a piston switch 12 lower end, the speed of control titration, and there is an interface top of piston, be connected with the lower end outlet of liquid reservoir 2, so that standard liquid enters in the micro titrator by this interface in the liquid reservoir 2.
Above-mentioned liquid reservoir 2, be used to store standard liquid, the upper end is an oval-shaped funnel, it is suitable for reading that the funnel position is higher than micro titrator 1, the lower end connects a catheter, and by piston switch 21, directly communicates with the interface of micro titrator 1 lower end, directly import in the micro titrator 1 by the standard liquid of piston switch 2 li of liquid reservoirs, promptly titratable.
In above-mentioned a kind of microburet, also have between the upper end of micro titrator 1 and liquid reservoir 2 one fixedly connected 3, be used for fixing micro titrator 1 and liquid reservoir 2.
Compared with prior art, the present invention has following beneficial effect:
1, the utility model provides a kind of microburet, and the more common buret of the design of pipe shaft is tiny, and titer is in the 10ML, can avoid content of material after a little while, and the standard liquid that consumes because of titration is few to produce bigger error.
2, a kind of microburet of the utility model, the liquid reservoir 2 of setting can join standard liquid in the micro titrator 1 easily and fast, exactly, behind the intact solution of micro titrator 1 titration, can add standard liquid continuously by liquid reservoir 2 continuously.The utility model is simple to operate, result of use good, and cost of manufacture is low, be convenient to popularize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structural representation of the present utility model as shown in Figure 1,
A kind of microburet, be a kind of microburet, comprise micro titrator 1 and liquid reservoir 2, micro titrator 1 is a cylinder, be used to contain the standard liquid that titration is used, have scale 11 on the pipe shaft, the standard liquid volume that the index titration consumes, there is a piston switch 12 lower end, the speed of control titration, there is an interface top of piston, is connected with the lower end outlet of liquid reservoir 2, so that standard liquid enters in the micro titrator by this interface in the liquid reservoir 2.Liquid reservoir 2, be used to store standard liquid, the upper end is an oval-shaped funnel, it is suitable for reading that the funnel position is higher than micro titrator 1, the lower end connects a catheter, and by piston switch 21, directly communicates with the interface of micro titrator 1 lower end, directly import in the micro titrator 1 by the standard liquid of piston switch 2 li of liquid reservoirs, promptly titratable.Also have between the upper end of micro titrator 1 and liquid reservoir 2 one fixedly connected 3, be used for fixing micro titrator 1 and liquid reservoir 2.
Method of operating: during use, pack in the liquid reservoir 2, open piston switch 21 with demarcating good standard liquid, allow solution enter in the micro titrator 1 by catheter, control imports the speed of solution, makes solution slowly arrive the position of micro titrator 1 pipe shaft graduation mark " 0 ", stops to import solution, will place erlenmeyer flask by titrimetric sample solution, open the piston switch 12 of micro titrator 1, the speed of control titration is carried out titration, till terminal point, record buret reading.The titration of second and third time is carried out in repetitive operation.
