Description

A geochemical chromatography column

Technical field:

The utility model belongs to the technical field of chemical equipment, in particular to a chromatographic column for geochemistry.

Background technique:

Column chromatography is the most commonly used separation and purification method in biological and chemical laboratories. During the entire separation and purification process, in addition to factors such as adsorbents, solvents, and solutes, the structure of the chromatography column itself also affects the separation and purification efficiency. At present, in organic chemical synthesis laboratories, chromatography columns are generally used under normal pressure or under pressure. These chromatography columns have many shortcomings in the process of use, especially in the liquid inlet link, which cannot guarantee The uniform distribution of the liquid greatly affects the purification efficiency, and it lacks the necessary lighting device, and does not have the function of recording the temperature and humidity during the purification process, which will bring inconvenience to the statistics and arrangement of data in the future. In addition, in the project of moving the chromatography column It is easy to fall off in the medium, causing damage to the chromatographic column, affecting the test cycle and good test results. the

Utility model content:

The technical solution adopted in the utility model is: a chromatography column for geochemical use, including a column body, a retaining handle and a piston, and a liquid homogenizer is provided on the top of the column body, and the liquid homogenizer includes an upper edge, a tapered funnel, an inverted cone A shaped funnel and a liquid equalizing plate, the liquid equalizing plate is provided with evenly distributed liquid separation holes, the outer diameter of the upper edge is larger than the outer diameter of the cylinder, the conical funnel, the inverted conical funnel and the liquid equalizing plate are located inside the cylinder; From top to bottom, the exterior of the cylinder is provided with a label box, a retaining handle, an anti-slip rubber sleeve, two symmetrically distributed arc lighting devices, a thermometer and a hygrometer. The arc lighting device includes an arc transparent body, LED lights, and buttons Battery box and switch, LED light and button battery box (51) are positioned at the inside of curved transparent body.

The liquid homogenizer is an integral structure and can be easily taken out from the cylinder.

The cylinder is made of glass material.

The material of the curved transparent body is transparent plastic or glass.

The material of the label box is transparent material or glass.

The arc lighting device is powered by a button battery.

The utility model has the beneficial effects of simple structure, reasonable design, safety and reliability, convenient use, low cost, and easy popularization and use on a large scale. During use, the liquid is poured into the column through the homogenizer. The design of the conical funnel prevents the operator from being hurt by splashing the liquid on the hand. The liquid is evenly distributed into the column after passing through the homogenizer. The efficiency and quality of purification are improved; the thermometer and hygrometer can accurately record the data of temperature and humidity in the purification process, which provides effective data support for analysis and research of the purification process; the arc lighting device is convenient to operate It is also beneficial for the operator to observe the purification situation at night, which is also conducive to the accurate recording of temperature and humidity; the described label box can place the relevant parameter descriptions of the purified substance, which can be more convenient for the operator to work and improve work efficiency; the described non-slip rubber sleeve And the stop handle can prevent the operator from slipping when moving the chromatographic column, reducing losses and costs.
