Abstract
Description
Technical Field
[0001] This utility model relates to the field of chromatography column technology, specifically to a chromatography column for nucleic acid protein sample processing. Background Technology
[0002] Nucleic acid and protein sample processing refers to the process of breaking down a sample to quantitatively transfer the analyte into a solution for analysis. This process is crucial in biological experiments because it directly affects the accuracy and reliability of subsequent experiments. Chromatographic columns are a method in chemical analysis used to separate various compounds in a mixture. In nucleic acid and protein sample processing, chromatographic columns primarily function in separation, purification, and analysis. Through their unique structure and separation mechanism, they can effectively process and separate nucleic acid and protein samples. However, current chromatographic columns still have the following shortcomings:
[0003] For example, patent application CN219764561U discloses a chromatographic column. This column can avoid interference from metal ions on materials, thus preventing interference with component identification. The ceramic coating has good acid and alkali resistance. The ceramic coating has good wear resistance, which increases the service life of the column body and the de-aging piston. The ceramic coating is radiation resistant and has high strength, but it is not easy to quickly disassemble and assemble, making regular maintenance inconvenient.
[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a chromatographic column for nucleic acid protein sample processing. Utility Model Content
[0005] The purpose of this invention is to provide a chromatographic column for nucleic acid and protein sample processing to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a chromatographic column for nucleic acid protein sample processing, comprising a column tube and a disassembly assembly. The column tube is an integrally formed stainless steel structure, and internal packing is provided inside the column tube. The disassembly assembly is located at both ends of the column tube and includes an external threaded connector, an internal threaded mounting sleeve, a threaded reinforcement hole, a reinforcement screw, a sample inlet / outlet, a silicone sealing gasket, and a plastic protective plug. The external threaded connector is located on the outer side of both ends of the column tube, and the outer surface of the external threaded connector is threadedly connected to the internal threaded mounting sleeve. Two sets of internal threaded mounting sleeves are symmetrically arranged, and threaded reinforcement holes are opened on the surfaces of the internal threaded mounting sleeves.
[0007] Furthermore, the inner side of the threaded reinforcement hole is threaded with reinforcement screws, and four sets of reinforcement screws are symmetrically arranged.
[0008] Furthermore, the internal threaded mounting sleeve has a sample inlet and outlet, and the inner surface of the sample inlet and outlet is provided with a silicone sealing gasket. A plastic protective plug is engaged and connected to the inner side of the sample inlet and outlet.
[0009] Furthermore, the chromatographic column tube has sieve plates that are snapped together at both ends, and a blade ring is provided on the outer side of the sieve plate.
[0010] Furthermore, a rubber sealing gasket is provided on the outer surface of the blade ring, and the blade ring is engaged with both ends of the chromatographic column tube.
[0011] Furthermore, the chromatographic column tube and the external threaded connector are a tightly connected integrated structure, and the surface of the chromatographic column tube is provided with protective components for enhanced protection.
[0012] Furthermore, the protective component includes an anti-slip pad, a stainless steel reinforcing mesh, a rigid reinforcing protective layer, and a polytetrafluoroethylene coating, with the anti-slip pad disposed on the outer surface of the chromatographic column tube.
[0013] Furthermore, the chromatographic column tube is provided with a stainless steel reinforcing mesh inside, and a rigid reinforcing protective layer is installed on the inner side of the stainless steel reinforcing mesh. The inner surface of the rigid reinforcing protective layer is provided with a polytetrafluoroethylene coating.
[0014] This invention provides a chromatographic column for nucleic acid and protein sample processing, which has the following beneficial effects:
[0015] 1. This utility model incorporates a disassembly and assembly component, comprising an external threaded connector, an internal threaded mounting sleeve, a threaded reinforcement hole, a reinforcement screw, a sample inlet / outlet, a silicone sealing gasket, and a plastic protective plug. In use, the internal threaded mounting sleeve is fixed to both ends of the chromatographic column tube through the threaded connection between the internal threaded mounting sleeve and the external threaded connector. The reinforcement screw is then threaded into the inner side of the threaded reinforcement hole to reinforce the connection between the internal threaded mounting sleeve and the external threaded connector. The plastic protective plug engages with the sample inlet / outlet to block it. The silicone sealing gasket enhances the sealing of the sample inlet / outlet. This allows for rapid disassembly and assembly of the entire device, facilitating equipment maintenance and upkeep, regular inspection and cleaning of the column interior, and extending the column's lifespan.
[0016] 2. This utility model incorporates a protective component, including an anti-slip pad, a stainless steel reinforcing mesh, a rigid reinforcing protective layer, and a polytetrafluoroethylene (PTFE) coating. During use, the anti-slip pad protects the outer side of the chromatographic column, enhancing its anti-slip effect and preventing it from slipping and falling. The stainless steel reinforcing mesh increases the overall hardness of the column, making it less prone to breakage. The rigid reinforcing protective layer improves the column's compressive strength, preventing deformation. The PTFE coating possesses excellent chemical corrosion resistance and high-temperature stability, enhancing the internal corrosion resistance of the column. This makes the device more stable and less susceptible to damage, with enhanced internal corrosion resistance and reduced risk of internal column damage. Attached Figure Description

The external threaded connector 301 is located on the outer side of both ends of the column tube 1, and the outer surface of the external threaded connector 301 is threadedly connected to the internal threaded mounting sleeve 302. Two sets of internal threaded mounting sleeves 302 are symmetrically arranged, and the surfaces of the internal threaded mounting sleeves 302 and the internal threaded mounting sleeves 302 are provided with threaded reinforcement holes 303.
[0023] The specific operation is as follows: During use, the internal threaded mounting sleeve 302 is fixed to both ends of the chromatographic column tube 1 by connecting the internal threaded mounting sleeve 302 to the external threaded connector 301. The connection between the internal threaded mounting sleeve 302 and the external threaded connector 301 is reinforced by connecting the reinforcing screw 304 to the threaded reinforcing hole 303. The sample inlet and outlet 305 are blocked by engaging the plastic protective plug 307 with the sample inlet and outlet 305. The sealing performance of the sample inlet and outlet 305 is enhanced by the silicone sealing gasket 306.
[0024] Please refer to Figure 1 and Figure 3 The threaded reinforcement hole 303 has a threaded connection to a reinforcement screw 304, and four sets of reinforcement screws 304 are symmetrically arranged. The internal threaded mounting sleeve 302 has a sample inlet / outlet 305, and a silicone sealing gasket 306 is provided on the inner surface of the sample inlet / outlet 305. A plastic protective plug 307 is engaged with the inner side of the sample inlet / outlet 305. The two ends of the chromatographic column tube 1 are engaged with a sieve plate 4, and a blade ring 5 is provided on the outer side of the sieve plate 4. A rubber sealing gasket 6 is provided on the outer surface of the blade ring 5, and the blade ring 5 is engaged with the two ends of the chromatographic column tube 1.
