Description

Technical Field

[0001] This utility model relates to the field of isotope separation technology, specifically to an isotope separation and purification column rack. Background Technology

[0002] Isotope separation is a technique that uses the mass difference between different isotopes to separate them. It is an important research tool in modern chemistry, physics, biology and other fields. Separation methods include bulk diffusion, ion exchange, gas centrifugation, laser separation and so on.

[0003] An isotope separation column is a tool used in isotope separation operations. Its structure consists of a hollow cylinder and a slender cylindrical tube connected to its lower end, with the lower end of the slender cylindrical tube being open. During the isotope separation process, the flow of gas or liquid is required to assist in the process, and the opening allows for smooth flow. The lower opening also facilitates the collection of the separated isotopes. For example, in some chemical exchange separation methods, lighter isotopes are enriched in the back zone of the separation column, while heavier isotopes are enriched in the front zone.

[0004] However, in the existing technology, the column holder used to set up the isotope separation column consists of two discs, one above the other, which directly clamp the separation column. This exposes the opening, allowing unremoved waste liquid inside to drip downwards, resulting in direct exposure of the chemical liquid. This is not only inconvenient to clean, but also poses a certain danger. Utility Model Content
