Description

Technical Field

[0001] The utility model relates to the field of laboratory devices, in particular to an improved cerium sulfate separating bottle. Background Art

[0002] Cerium sulfate solution is a widely used reagent in chemical analysis, particularly in redox titrations. As a strong oxidant, it reacts with a variety of reducing substances. Its applications in analytical chemistry include, but are not limited to, determining the content of certain metal ions, acting as a catalyst in certain chemical reactions, and detecting the degree of oxidation of organic matter in environmental monitoring. These properties make cerium sulfate an indispensable standard solution in laboratories.

[0003] However, currently, cerium sulfate standard solutions are typically stored in narrow-mouthed reagent bottles. While this design helps reduce volatilization and external contamination, it also introduces numerous inconveniences during practical use. When transferring the solution from such a narrow-mouthed bottle to a beaker or burette, the narrow mouth of the bottle makes pouring the solution difficult and prone to errors. This operation not only increases the complexity of the experiment but can also lead to solution waste and potentially pose safety risks to the experimenter due to spillage during the operation.

[0004] In addition, when pouring liquid into a small-mouthed reagent bottle, the experimenter needs to be extra careful to avoid prolonged contact between the solution and air, which may affect the stability and accuracy of the solution. In some cases, improper operation may also introduce impurities, affecting the reliability of the experimental results. Utility Model Content

[0007] Furthermore, a hollow long strip slide groove is provided on the outer cylinder, and the limit block is configured to be able to slide along the slide groove and be positioned at any position in the slide.

[0008] Furthermore, a scale is provided on one side of the slide groove.

[0009] Furthermore, a protective cover is provided on the outside of the liquid outlet, and the protective cover is fixedly connected to the base via a connecting line.

[0010] Furthermore, anti-slip grooves are provided on the outer side of the connecting end.

The liquid inlet check valve at the bottom controls the entry of the solution and guides it to the base through the liquid inlet pipe. The setting of the extension arm makes the operation more convenient. The liquid outlet pipe inside it is combined with the outer piston tube and the inner piston cylinder. By adjusting the height of the limit block on the outer cylinder, the height to which the outer cylinder and the inner piston cylinder are lifted can be adjusted. When the limit block and the bottom of the limit ring are against each other, the outer cylinder can no longer be lifted. At this time, only a fixed amount of cerium sulfate can be extracted from the reagent bottle. Then, by opening the control valve and pressing the outer cylinder downward, the cerium sulfate liquid between the outer piston tube and the inner piston cylinder can be squeezed out from the liquid outlet. This enables quick, convenient and quantitative use of cerium sulfate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings. However, the following embodiments only list preferred embodiments, which only serve to explain and help understand the present invention and cannot be understood as limiting the present invention.

[0023] refer to Figure 1-3 The top of the inner piston tube is fixedly provided with an inner piston cylinder 12, and the inner piston cylinder and the outer piston cylinder are interference fit. The top of the inner piston cylinder 12 is fixedly connected to the outer cylinder 14 through a connecting cover 13. A control valve 15 for controlling the on-off of the liquid outlet pipe is provided on the extension arm, and a limit block 16 for adjusting the height is provided on the outer cylinder.

[0024] The above technical solution discloses an improved cerium sulfate separation bottle, in which the separation unit is tightly connected to the reagent bottle through the connecting end to form a sealed system. The base fixes the connecting end and supports the entire separation unit. The liquid inlet check valve at the bottom controls the entry of the solution and guides it to the base through the liquid inlet pipe. The setting of the extension arm makes the operation more convenient. The liquid outlet pipe inside it is combined with the outer piston tube and the inner piston cylinder. By adjusting the height of the limit block on the outer cylinder, the height to which the outer cylinder and the inner piston cylinder are lifted can be adjusted. When the limit block and the bottom of the limit ring are against each other, the outer cylinder can no longer be lifted. At this time, only a fixed amount of cerium sulfate can be extracted from the reagent bottle. Then, by opening the control valve and pressing the outer cylinder downward, the cerium sulfate liquid between the outer piston tube and the inner piston cylinder can be squeezed out from the liquid outlet. The cerium sulfate can be taken quickly, conveniently and quantitatively.

[0025] As a preferred embodiment, the outer cylinder is provided with a hollow elongated chute 17, and the limit block 16 is configured to be able to slide along the chute and be positioned at any position within the chute. A scale 18 is provided on one side of the chute. The elongated chute 17 cooperates with the limit block so that it can slide freely along the chute and can be positioned at any position within the chute. This flexibility allows the user to easily adjust the maximum height of the outer cylinder and the inner piston cylinder according to experimental requirements or personal operating habits. To achieve quantitative control of liquid extraction. In addition, the scale 18 on one side of the chute provides the user with an accurate height reference, ensuring the accuracy of the experimental operation. This design greatly improves the convenience of operation.

[0026] As a preferred embodiment, based on any of the above technical solutions, the liquid outlet 10 is provided with a protective cover 19 on the outside, and the protective cover is fixedly connected to the base 3 via a connecting line 20. The above solution provides additional safety and protection, ensuring that the liquid outlet will not be accidentally contaminated or damaged during use. The presence of the protective cover can prevent external impurities from entering the separatory bottle, and also reduces damage to the liquid outlet caused by vibration or impact during transportation or storage. In addition, the fixed connection method of the protective cover ensures that it will not accidentally fall off or be lost during operation.

[0027] Optionally, the outer side of the connecting end is further provided with anti-skid grooves 21. The anti-skid grooves make it easier to disassemble and assemble the liquid separation unit. In addition, the reagent bottle is optionally a glass bottle.

[0028] More preferably, a window 22 is provided on one side of the front end of the extension arm, and the liquid outlet pipe 7 is exposed outside the extension arm through the window 22, so as to facilitate observation of the liquid in the liquid outlet pipe.

[0029] Generally speaking, the liquid inlet check valve 4 includes a check valve body 41 connected to the base 3 and the liquid inlet pipe 5 respectively, and a ceramic ball 42 is arranged inside the check valve body. The ceramic ball prevents the cerium sulfate in the inner cavity from flowing back into the reagent bottle through its own weight.

[0030] The embodiments described above are merely descriptions of preferred implementation methods of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
