Description
Technical field
The present invention relates to one and carry out titrimetric instrument buret.
Background technology
Buret is widely used in titration operation, it is requisite experimental apparatus in titrimetry, buret conventional at present has acid buret and base buret, because their structure is different with purposes, different burets to be selected according to different titrant, and correct specification is required to titration operation posture, otherwise leakage will be caused or affect the accuracy of titration results.
The cock of acid buret is made up of the glass of polishing, and strictly supporting with former buret, once damage, whole buret has also just been scrapped, and also needs to be coated with vaseline during use, easily causes and stains or blocking; Base buret not only operates effort, and its emulsion tube is easily aging and pollute titrant.Two kinds of burets can not be general, both added the expense buying instrument, and also brought inconvenience to use.
Summary of the invention
The technical problem to be solved in the present invention is exactly the deficiency existed for two kinds of now conventional burets, a kind of novel universal buret is provided, it can not only be applicable to the titrimetry of various solution, and easy to operate, can not result in blockage, leakage and solution stains.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of novel universal buret, comprise glass metrology pipe, connector, water dropper body and tune handle, it is characterized in that: on glass metrology pipe, cover has check nut, connector is carved with the screw thread supporting with check nut, screws check nut and glass metrology pipe and connector can be made reliably to be connected and to seal; Respectively have the mesoporous channels that elongated in connector and in water dropper body, connector and water dropper body are threaded connection and seal; Tuning handle is be with the bead of mesopore to be connected by round bar to revolve hand structure, has the grooving placed and tune handle, will tune handle and be put into after bottom water dropper body, screw the bead sphere compression that connector can tune handle bottom water dropper body; Regulate the hand that revolves tuning handle can the relative position of bead in water dropper body of control cincture mesopore, thus control rate of titration.
Described glass metrology pipe there is metering scale, is convenient to the liquor capacity that calculating titration consumes.
O-ring seal is had, the sealing that reinforcing glass gauge line is connected with connector between described check nut and connector.
After described connector is connected with water dropper body, regulates and tune the position of handle, can make to tune mesopore in the mesopore of handle bead and connector and water dropper body point-blank, be convenient to carry out large discharge rapid titration.
The bead hardness of described band mesopore is greater than the hardness of water dropper body and connector, is not easy leakage and is easy to control rate of titration.
Handle will be tuned be put into by grooving of opening bottom water dropper body and suitably screw after bead sphere compresses by connector bottom water dropper body, smooth sphere owing to contacting with each other, and spheroid can be comparatively hard plastic material, water dropper body and connector can be slightly soft plastic material, suitably screw connector and water dropper body just can realize positiver sealing and bead can be driven by turn handle flexibly, adjustment tunes handle just can control reagent titration, can be linearity by expanding channels in water dropper body and connector when aperture in ball is in vertical configuration, realize large discharge rapid titration, suitable adjustment tunes handle capable of being and controls reagent conducting cross-sectional sizes, titration flow is progressively diminished until close completely.
Compared with prior art, beneficial effect of the present invention is:
The Acidity of Aikalinity of the present invention to volumetric soiutions does not limit, most solution in chemical analysis all can use this buret to realize titration operation, can not only easily titrimetry accurately, and thoroughly solve that old-fashioned buret easily blocks, stains, leakage, inconvenient operation, emulsion tube easily aging and glass cock easily smash can not be supporting etc. many key issues, enjoy the welcome of teacher, student and different users.
Standard component can be made in the interface section of glass metrology pipe and connector by this buret, and buret just can replace arbitrarily the gauge line of different size and volume in use, as 50ml, 25m, 5ml even microburette of 1ml, greatly facilitates use.Meanwhile, this universal burette structure is simple, cost is low, durable, is also convenient to production and processing, easily promotes, have stronger practical value and market outlook.
