Abstract
The invention discloses a novel general burette, which comprises a glass metering tube, a connecting body, a dripper body and a rotary adjusting handle, wherein the glass metering tube is sleeved with a locking nut; a thread matched with the locking nut is carved on the connecting body; a tenuous central hole channel is formed in each of the connecting body and the dripper body; the connecting body and the dripper body are in threaded connection and are sealed; the rotary adjusting handle is formed by connecting a small ball with a central hole with a rotary hand structure through a round rod; a cutting groove for holding the rotary adjusting handle is formed in the bottom of the dripper body and the relative position of the small ball with the central hole in the dripper body can be controlled by adjusting the rotary hand of the rotary adjusting handle. According to the novel general burette, not only can the titrimetry be easily and accurately performed, but also multiple key problems that a conventional burette is prone to blockage, contamination and liquid leakage and is inconvenient to operate, a latex tube is prone to aging and a glass rotary plug is easily broken and cannot be matched are solved, so that the novel general burette has a relatively high practical value and wide market prospect.
Description
Technical field
The present invention relates to a kind of titrimetric instrument buret that carries out.
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 standard, otherwise will cause leakage or affect the accuracy of titration results.
The cock of acid buret is made by 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 during 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 to use, brings inconvenience.
Summary of the invention
The technical problem to be solved in the present invention 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 present invention takes 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, regulate the position tune handle, can make to tune the mesopore of handle bead and the mesopore in connector and water dropper body 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, owing to contacting with each other, it is smooth sphere, 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, in ball, aperture 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, beneficial effect of the present invention is:
The present invention is to the not restriction of the Acidity of Aikalinity of volumetric soiutions, most solution in chemical analysis all can be used 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 50ml, 25m, the 5ml microburette of 1ml even, 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.
