Description
Technical field
The utility model relates to one and carries out titrimetric instrument buret.
Background technology
Buret is widely used in titration operation, it is requisite experimental apparatus in titrimetry, conventional buret has acid buret and base buret at present, because of their structure different with purposes, to select different burets according to different titrant, and titration operation posture is required to correct specification, otherwise will cause leakage 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 also just scrapped, and also needs to be coated with vaseline when use, easily causes and stains or stop up; Base buret not only operates effort, and its emulsion tube is easily aging and titrant is polluted.Two kinds of burets can not be general, both increased the expense of buying instrument, also brings inconvenience to use.
Utility model content
The technical problems to be solved in the utility model is exactly the deficiency existing 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 utility model is taked following technical scheme:
A kind of novel universal buret, comprise glass gauge line, connector, water dropper body and tune handle, it is characterized in that: on glass gauge line, cover has check nut, on connector, be carved with the screw thread supporting with check nut, screw check nut and can make glass gauge line reliably be connected and seal with connector; In connector and in water dropper body, respectively have an elongated mesoporous channels, connector and water dropper body are threaded connection and seal; The bead that tunes handle and be with mesopore is connected and is revolved hand structure by round bar, and water dropper body bottom has places the grooving that tunes handle, will tune handle and be put into behind water dropper body bottom, screws the bead sphere that connector can tune handle and compresses; Adjusting tunes revolving hand and can controlling bead with the mesopore relative position in water dropper body of handle, thereby controls rate of titration.
On described glass gauge line, there is metering scale, be convenient to calculate the liquor capacity that titration consumes.
Between described check nut and connector, there is O-ring seal, the sealing that reinforcing glass gauge line is connected with connector.
After described connector is connected with water dropper body, regulates and tune the position of handle, can make to tune mesopore in mesopore and connector and the water dropper body of handle bead point-blank, be convenient to carry out the quick titration of large flow.
The described hardness that is greater than water dropper body and connector with the bead hardness of mesopore, is not easy leakage and is easy to control rate of titration.
To tune handle is put into water dropper body bottom by the water dropper body bottom grooving of opening and suitably screws connector by after bead sphere compression, smooth sphere owing to contacting with each other, and spheroid can be compared with hard plastic material, water dropper body and connector can be slightly soft plastic material, suitably screwing connector and water dropper body just can realize positiver sealing and can drive bead by flexible turn handle, adjusting tunes handle just can control reagent titration, when aperture in ball can be connected to linearity by passage in water dropper body and connector in vertical configuration, realize the quick titration of large flow, suitably regulate and tune handle capable of being control reagent conducting cross-sectional sizes, titration flow is progressively diminished until close completely.
Compared with prior art, the beneficial effects of the utility model are:
The utility model does not limit the Acidity of Aikalinity of volumetric soiutions, most solution in chemical analysis all can use this buret to realize titration operation, easily titrimetry accurately, and thoroughly solved that old-fashioned buret easily stops up, contamination, leakage, inconvenient operation, emulsion tube easily aging and glass cock easily smash can not be supporting etc. many key issues, enjoy teacher, student and different users's welcome.
This buret can be made standard component by the interface section of glass gauge line and connector, and buret just can be replaced arbitrarily the gauge line of different size and volume in use, as the even microburette of 1ml of 50ml, 25m, 5ml, greatly facilitates use.Meanwhile, this universal burette is simple in structure, cost is low, durable, is also convenient to production and processing, easily promotes, and has stronger practical value and market outlook.
