Abstract
This application discloses a kind of volumetric flask.Including bottle, bottleneck, graduation mark, the bottleneck is provided with a half outside semi-cylindrical hill, the raised top for being located at graduation mark, the bottleneck also includes a liquid-feeding tube, the liquid-feeding tube is made up of inner and outer tubes, the top of said inner tube it is outwardly convex go out chimb, the chimb may be stuck in the bottleneck of volumetric flask, the bottom of the outer tube is provided with the fixture block that can be folded up and down, fixture block is located at the bottom outside of outer tube, and be integrally formed with outer tube, said inner tube is flexibly connected with the outer tube in the vertical direction.By setting liquid-feeding tube on the bottleneck top of volumetric flask, during the liquid relief into volumetric flask and constant volume, drained without using glass bar, it is simple to operate.
Description
Technical field
The present invention relates to a kind of capacity utensil, and in particular to the volumetric flask of more convenient constant volume in a kind of chemical experiment.
Background technology
Volumetric flask is a kind of flat bottle of thin neck pyriform, is made up of colourless or brown glass, is to prepare the fine instrument of the accurately solution of certain substance withdrawl syndrome with ground glass stopper or plastic plug.
Volumetric flask used in laboratory at present, bottleneck is too thin, in order to ensure on the non-sticky inwall to volumetric flask graduation mark above section of solution, it need to be drained during inside constant volume liquid relief with glass bar, operate cumbersome, solution is leaked outside with glass bar easy misoperation, certain influence can also be produced on experiment accuracy.
The content of the invention
In view of drawbacks described above of the prior art or deficiency, it is expected to provide a kind of volumetric flask with catheter, so as to solve, liquid easily leaks outside during constant volume, it is inconvenient for operation the problem of.
The present invention is solves the problems, such as to provide a kind of volumetric flask in above-mentioned background technology, including bottle, bottleneck, graduation mark, the bottleneck is provided with a half outside semi-cylindrical hill, the raised top for being located at graduation mark, the bottleneck also includes a liquid-feeding tube, the liquid-feeding tube is made up of inner and outer tubes, the top of said inner tube it is outwardly convex go out chimb, the chimb may be stuck in the bottleneck of volumetric flask, the bottom of the outer tube is provided with the fixture block that can be folded up and down, fixture block is located at the bottom outside of outer tube, and it is integrally formed with outer tube, said inner tube is flexibly connected with the outer tube in the vertical direction.
Further, the side that said inner tube contacts with the outer tube is provided with bar shaped protruding rail, and strip groove is provided with the position corresponding with outer tube, and inner tube relatively moves in vertical direction with outer tube along strip groove.
Further, the side of said inner tube is provided with some projections and projection groove, and the projection is fixedly connected on inside projection groove by bullet block, and the outer tube is provided with some grooves corresponding with projection, and the projection and groove can be used to change the length of liquid-feeding tube.
Further, the liquid-feeding tube generally plastic material.
The technical scheme provided according to the embodiment of the present application, by setting liquid-feeding tube on the bottleneck top of volumetric flask, during the liquid relief into volumetric flask and constant volume, drained without using glass bar, it is simple to operate；In addition, liquid-feeding tube is arranged to change the structure of length, conveniently can use in several cases；Liquid-feeding tube can be dismantled from volumetric flask, facilitate volumetric flask and be used as needed liquid-feeding tube.
