Description

Technical Field

[0001] The utility model relates to the field of thin layer chromatography analysis equipment, in particular to a chromatography cylinder with an adjustable development groove. Background Art

[0002] The chromatography cylinder is a laboratory equipment required for thin layer chromatography. When in use, a developing agent is added to the bottom of the chromatography cylinder, and then the thin layer plate is placed in the cylinder so that the bottom of the plate is in contact with the developing agent.

[0003] The utility model patent application number CN201520985282 discloses a multifunctional thin-layer chromatography development device, in which multiple chambers are separated by horizontal and vertical partitions in a glass tank, and a chromatography plate is placed independently in each chamber.

[0004] The utility model patent application number CN201320019804 discloses a multifunctional chromatography cylinder, which includes a V-shaped expansion groove with adjustable expansion height. The chromatography plate is placed in the expansion groove or tilted against the expansion groove.

[0005] The size and volume of the development tank of the existing chromatography cylinder is fixed. When a chromatography plate with a smaller width is used, the bottom surface is too large and too deep, resulting in waste of developing agent. When a chromatography plate with a smaller height is used, the chromatography cylinder is too deep and inconvenient to take out. Such a structure will cause waste of reagents and is not conducive to practical operation. Utility Model Content

[0006] The utility model addresses the technical problem that the current thin layer chromatography equipment cannot adjust the size of the development tank, and provides a chromatography cylinder with an adjustable development tank, which is achieved through the following technical solutions:

[0007] A chromatography cylinder with an adjustable expansion tank, the chromatography cylinder comprising a chromatography cylinder body 1, a movable partition 2, a chromatography cylinder cover 3 and a liquid tank 5, the chromatography cylinder body 1 being a cylinder body with an open top, the chromatography cylinder cover 3 matching the top of the chromatography cylinder body 1, the movable partition 2 being vertically arranged in the chromatography cylinder 1, the horizontally arranged liquid tank 5 being detachably fixedly connected to the movable partition 2, the liquid tank 5 having an open top, the liquid tank 5 comprising a liquid-filling side plate 51 and a liquid-filling bottom plate 52 connected to the movable partition 2, and an expansion tank 8, the expansion tank 8 being accommodated in a hollow structure formed by the liquid-filling side plate 51 and the liquid-filling bottom plate 52, and the expansion tank 8 being movable horizontally along the length of the liquid tank 5 in the liquid tank 5.

[0008] By integrating a push-pull expansion tank 8 within the liquid tank 5, a resizable expansion tank is achieved. Together, the liquid tank 5 and expansion tank 8 form a semi-enclosed space with an open top, into which the chromatography plates and developer are placed to complete the experiment. During operation, the expansion tank can be adjusted to the width of the plates, controlling developer usage and reducing environmental pollution and manufacturing costs caused by developer waste. Furthermore, the chromatography cylinder 1 can accommodate multiple movable partitions 2 containing liquid tanks 5, allowing each cylinder to independently perform chromatography experiments with multiple plates, improving experimental efficiency.

[0009] As a preferred solution of the present invention, the movable partition plate 2 is provided with a vertical height slot 7 , and the liquid tank 5 is fixed to the movable partition plate 2 by bolts 6 matching the height slot 7 .

[0010] The height of the liquid tank 5 fixed on the movable partition 2 can be adjusted by the height slot 7 and the bolt 6, which can keep the upper edge of the chromatography plate near the cylinder mouth of the chromatography cylinder, making it easy to observe the chromatography situation and convenient to take it, reducing experimental operation errors.

[0011] Preferably, the inner surfaces of the liquid storage tank 5 and the development tank 8 are frosted.

[0012] The frosting treatment ensures that after the pull-out structure changes its width, the liquid-filling tank 5 and the expansion tank 8 maintain the density of the overall structure, ensuring that there is no leakage or seepage of liquid.

[0013] Preferably, the edge of the movable partition 2 and the contact surface between the chromatography cylinder body 1 and the chromatography cylinder cover 3 are frosted.

[0014] The frosting treatment ensures closer contact between the edge of the movable partition 2 and the chromatography cylinder 1, and between the chromatography cylinder 1 and the chromatography cylinder cover 3, thereby forming a stable and enclosed space.

[0015] Preferably, the chromatography cylinder 1 is made of transparent borosilicate glass.

[0016] Preferably, a handle 4 is provided on the chromatography cylinder cover 3 .

[0017] Compared with the prior art, the present invention achieves the following technical effects:

[0018] 1. Hygienic, environmentally friendly and cost-saving. The utility model adjusts the developing tank according to the width of the chromatography plate to be analyzed, controls the amount of developing agent, and reduces environmental pollution and manufacturing costs caused by waste of developing agent.

[0019] 2. Convenient. The height of the liquid tank fixed on the partition is adjustable, which can keep the upper edge of the chromatography plate close to the mouth of the chromatography tank, making it easy to observe the chromatography situation and easy to take out, reducing experimental operation errors.
