Description
Technical field:
The utility model relates to a kind of chemical industry measurement instrument, particularly relates to the special buret of a kind of chemical analysis.
Background technology:
Buret is used to the volumetric apparatus of accurately releasing Uncertainty liquid.With elongated and uniform glass tube is made, pipe has scale, and lower end is Yi Jianzui, and centre has section door to be used for controlling the speed of titration.Buret (burette) is divided into base buret and acid buret.The former has the liquid reagent of erosion action to glass tube for measuring; The latter has the liquid of erosion action to rubber for measuring.Buret capacity is generally 50mL, and each large lattice of scale are 1mL, and each large lattice is divided into again 10 little lattice, therefore each little lattice is 0.1mL.Degree of accuracy is one of percentage.Can be accurate to 0.01ml. buret is an elongated tubular container, and one end has plug switch, it has graduation indication and measures.General less at the scale reading on top, the reading by bottom is larger.
When titration, the amount of liquid added need not just in time fall within scale mark, as long as the amount of reading solution that can be correct.After the amount of liquid in pipe before titration being deducted titration during experiment, the storage of liquid in pipe is the consumption of volumetric soiutions.The switch of bottom effectively can control the flow velocity of vs, when making titration complete, in the conical flask under can in time stopping vs flowing into it.Vs can be added fast away from during titration end-point, save the time needed for experiment.If buret does not first dry completely when for using, then, before formal interpolation vs, buret should scrub twice with vs to be filled, avoids the liquid contamination vs being attached to tube wall.Buret because of the mouth of pipe narrow and small, when filling vs, should careful filling, spill to prevent vs.Funnel can be aided with if desired and be put in the help filling of mouth of pipe upper end.Buret can not have bubble in pipe after loading liquid, if having bubble application rubber or other article that can not crack glass to rap tube wall, allows bubble floating go out liquid level.Also air may be had in the channel of plug switch to exist, and now should reverse plug rapidly for several times, then bubble can be discharged.Buret should remain on vertical position in time using, and should not tilt, in order to avoid there is error when reading scale.
Traditional buret is in order to show less numerical value, and therefore scale mark is had to the more crypto set that arranges, but this design brings reading inconvenience, the problem that personal error is large.
Utility model content:
In order to solve the problem, it is easy that the utility model provides a kind of reading, effectively reduces the technical scheme of error.
The special buret of a kind of chemical analysis, main body is buret, comprise the control piston bottom canals of stilling and canals of stilling, canals of stilling outer surface is provided with two slide rail As contour with canals of stilling and slide rail B, slide rail A is fixedly connected with canals of stilling outer wall with slide rail B lower surface, upper surface is on same level, is provided with scale mark between slide rail A and slide rail B, and slide rail A and slide rail B is flexibly connected optical amplification device.
As preferably, optical amplification device is cube structure, and optical amplification device centre position is provided with optical lens, optical amplification device coboundary fixed installation level meter.
As preferably, be provided with arm bottom canals of stilling, 10 ~ 30mm bottom arm distance canals of stilling, control piston is fixedly installed on arm.
As preferably, arm is 90 ° of bending glass tubes, and arm one end is fixedly connected with canals of stilling, and the arm other end is the titration mouth that bore reduces gradually.
The beneficial effects of the utility model are:
(1) canals of stilling outer surface of the present utility model is provided with two slide rail As contour with canals of stilling and slide rail B, slide rail A and slide rail B installs optical amplification device, comparatively can be easy to read reading accurately from optical amplification device, improve the practicality of buret.
(2) optical amplification device coboundary fixed installation level meter in the utility model, can be easy to find out whether buret prevents from steadily, reducing personal error further thus.
(3) in this utility model, be provided with arm bottom canals of stilling, 10 ~ 30mm bottom arm distance canals of stilling, liquid in buret is fully precipitated, and guaranteed discharge measures the pure of the liquid come.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 is slide rail A and slide rail B and optical amplification device CONSTRUCTED SPECIFICATION figure.
Embodiment:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the special buret of a kind of chemical analysis, main body is buret, comprise the control piston 2 bottom canals of stilling 1 and canals of stilling, canals of stilling 1 outer surface is provided with two slide rail A3s contour with canals of stilling 1 and slide rail B4, as shown in Figure 2, slide rail A3 is fixedly connected with canals of stilling 1 outer wall with slide rail B4 lower surface, upper surface is on same level, is provided with scale mark 5 between slide rail A3 and slide rail B4, and slide rail A3 and slide rail B4 is flexibly connected optical amplification device 6.Comparatively can be easy to read reading accurately from optical amplification device 6, improve the practicality of buret.Be provided with arm 7 bottom canals of stilling 1, arm 7 is apart from 10 ~ 30mm bottom canals of stilling 1, and control piston 2 is fixedly installed on arm 7.Arm 7 is 90 ° of bending glass tubes, and arm 7 one end is fixedly connected with canals of stilling 1, and arm 7 other end is the titration mouth that bore reduces gradually.Liquid in buret is fully precipitated, and guaranteed discharge measures the pure of the liquid come.
