Abstract
The utility model provides a erlenmeyer flask with spiral flow disturbing line, includes erlenmeyer flask (1), its characterized in that: the lower part of the inner wall of the conical bottle body (1) is provided with a spiral line-shaped bulge (11); the spiral linear bulge (11) is inwards bulged from the inner wall of the conical bottle body (1) and arranged around the circumference of the conical bottle body (1). When rocking this embodiment erlenmeyer flask, solution forms convection current from top to bottom along the motion of spiral line form arch in the bottle, eliminates advection attitude or quiet flow attitude that liquid appears in the bottle, has promoted solution mixture or dissolved oxygen very effectively to realized solution mixture or promoted dissolved oxygen volume in short time, to unicellular biological culture experiment, promoted dissolved oxygen volume and can effectively prevent unicellular biological's caking.
Description
Technical Field
The utility model relates to a chemistry, biological assay container, concretely relates to erlenmeyer flask.
Background
Erlenmeyer (Conical flash), a laboratory-mounted glass instrument, was invented in 1861 by German chemists, Elunmeier (Richard Erlenmeyer). Is a reactor with a triangular longitudinal section made of hard glass. The mouth is small, the bottom is large, and the reaction is sufficient and liquid is not easy to spill out when oscillation is carried out in the titration process. The container may be heated in a water bath or on an electric furnace. The appearance is in the shape of a flat-bottomed cone, the lower part is wide and the upper part is narrow, the appearance is provided with a cylindrical neck part, the upper part is provided with an opening which is wider than the neck part, and the opening can be sometimes closed by a plug made of cork or rubber. The bottle body is provided with a plurality of scales to mark the capacity of the bottle body.
Erlenmeyer flasks are commonly used for chemical titration reactions, but also in other experiments, such as cell culture vessels in the biological field.
In the experimental process, in order to ensure that the solution fully reacts, the cone needs to be continuously shaken to ensure that the solution in the bottle oscillates, the common cone-shaped bottle is a cone-shaped light bottle, and in order to save time and accelerate the solution mixing or the solution dissolving oxygen, the shaking amplitude of the cone-shaped bottle can be increased, but the flat flow state or the static flow state still appears in the bottle, namely the speed of mixing and dissolving oxygen is still slow.
Therefore, how to improve the structure of the conical flask and increase the mixing and oxygen dissolving speed is the subject to be studied by the present invention.
Disclosure of Invention
The utility model aims at providing a erlenmeyer flask with spiral flow disturbing line to eliminate solution flat flow state or quiet flow state in the bottle and appear when rocking for mix and the speed of dissolved oxygen.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a conical bottle comprises a conical bottle body, wherein a spiral linear bulge is arranged at the lower part of the inner wall of the conical bottle body; the spiral linear bulge is formed by inwards bulging the inner wall of the conical bottle body and is arranged around the circumference of the conical bottle body.
In the above aspect, the spiral-shaped protrusion is an integrally formed protrusion when the conical bottle body is processed. Or the spiral linear bulge is externally fixed on the inner wall of the conical bottle body.
In the above scheme, the bottom wall of the conical bottle body is provided with the sensing element, the sensing element comprises a detection end arranged on the inner side of the bottom wall of the conical bottle body, a metal contact arranged on the outer side of the bottom wall of the conical bottle body and a conductor connected between the detection end and the metal contact, and the conductor is hermetically penetrated and embedded in the bottom wall.
The utility model discloses has following effect: the utility model discloses a set up the spiral line form arch on the inner wall, make it when rocking the erlenmeyer flask, convection current about the spiral line form protruding motion formation is easily followed to solution in the bottle, the advection or the quiet flow state that liquid appears in the elimination bottle, the solution is mixed or dissolved oxygen has been promoted very effectively, thereby realized solution mixture or promoted dissolved oxygen volume in shorter time, to unicellular biological culture experiment, promote dissolved oxygen volume and can effectively prevent unicellular biological's caking, and prevent that the cell from taking place anaerobic metabolism because of the oxygen deficiency at the erlenmeyer flask part.
Drawings
Fig. 1 is a schematic cross-sectional view of an embodiment of the present invention;
fig. 2 is a schematic perspective view of an embodiment of the present invention.
In the above drawings: 1. a conical flask body; 11. a spiral-shaped protrusion.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
example (b): referring to fig. 1 and 2:
a conical bottle with a spiral flow disturbing line comprises a conical bottle body 1 and a bottle cap (not shown in a bottle cap drawing), wherein the bottle cap can be arranged or not in practice, and is selected and matched according to experimental needs.
Referring to fig. 1 and 2, a spiral protrusion 11 is formed at the lower portion of the inner wall of the conical body 1. The spiral line-shaped protrusion 11 protrudes inward from the inner wall of the conical flask body 1 and is disposed around the circumference of the conical flask body 1.
Referring to fig. 1 and 2, the spiral protrusion 11 has a single thread shape, and may have a multiple thread shape.
The spiral line-shaped protrusion 11 is integrally formed during the processing of the conical bottle body, and may be externally fixed on the inner wall of the conical bottle body, such as being embedded in the inner wall of the conical bottle body.
The sensing device is characterized in that a sensing element is arranged on the bottom wall of the conical bottle body 1, the sensing element comprises a detection end arranged on the inner side of the bottom wall of the conical bottle body 1, a metal contact arranged on the outer side of the bottom wall of the conical bottle body 1 and a conductor connected between the detection end and the metal contact, and the conductor is hermetically penetrated and embedded in the bottom wall.
This embodiment is through setting up the spiral line form arch on the inner wall, makes it when rocking the erlenmeyer flask, and solution forms upper and lower convection current along the spiral line form protruding motion in the bottle, eliminates advection attitude or the quiescent current attitude that liquid appears in the bottle, has promoted solution mixture or dissolved oxygen very effectively to realized solution mixture or promoted dissolved oxygen volume in shorter time, to unicellular biological culture experiment, promote dissolved oxygen volume and can effectively prevent unicellular biological caking.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
