Chemiluminescence Immunoassay Analyzer Seals

A chemiluminescence immunoassay analyzer is a high-precision medical testing equipment, that is widely used in hospitals, physical examination centers, and other places to detect tumor markers, infectious diseases, hormones, and other biomarkers. One of the core components of the equipment is the seal, which plays a vital role in ensuring the stability of the reagents and preventing cross-contamination.

The main function of the seal is to ensure the tightness of the reagent bottle during storage and use, prevent the volatilization and spillage of the reagent, and also avoid external contaminants from entering the reagent bottle, affecting the purity of the reagent and the accuracy of the experimental results. According to the patented technical data, a fully automatic chemiluminescence immunoassay analyzer reagent sealing cap manufacturing method involves the design of the top cap, the bottom cap, and the middle cap. This design forms a sealing cover through a three-layer structure, and the middle cover can be rotated, and the middle cover is driven to rotate by toggling the rotating piece to realize the correspondence and sealing of the sample filling hole.

Specifically, the top and bottom caps are provided with dosing holes, and the middle cap is provided with rotating parts and gaskets. When it is necessary to add a sample, the rotating part is against the limiting part, so that the sampling hole on the middle cover corresponds vertically to the filling hole on the top cover and the bottom cover, to realize the sample filling. After the sample filling is completed, the rotating part is reversed to make the sealing gasket correspond to the filling holes on the top and bottom covers, to realize the external sealing of the whole cover. This design can effectively solve the problems of reagent volatilization, spillage, and contamination caused by the weak sealing of rubber porous bottle caps.

Material selection

Rubber: It has good elasticity and sealing, such as nitrile rubber, good chemical corrosion resistance, and can adapt to the environment of a variety of reagents in the chemiluminescence immunoassay analyzer; Silicone rubber, with excellent high and low-temperature resistance, can maintain good sealing performance in a wide temperature range, suitable for sealing parts under different temperature conditions in the instrument.

Plastics: Some engineering plastics, such as PTFE, have a very low coefficient of friction and good chemical stability and can be used for components that require high-precision sealing and low friction, such as certain valves or sliding seals.

Function

Prevent reagent leakage: The reagents used in chemiluminescence immunoassay analyzers are usually corrosive or biohazardous, and seals can effectively prevent reagent leakage, protect the internal parts of the instrument from corrosion, and avoid operators from coming into contact with dangerous reagents.

Guaranteed inspection accuracy: Seals help to create a stable inspection environment during the inspection process. For example, during photometering, a good seal can prevent external light interference, ensure that the photometering components accurately measure the luminescence signal of the sample, and thus improve the accuracy of the detection results.

Maintain the normal operation of the instrument: The seal can prevent dust and impurities from entering the instrument, prevent it from causing damage to the optical system, electronic components, and mechanical parts of the instrument, and ensure the normal operation and service life of the instrument.

In addition, the design of the seal includes a threaded ring, which is tightly connected to the reagent bottle by thread to ensure the stability of the connection. A sealing ring is arranged between the bottom surface of the cylinder wall of the top cover and the upper surface of the bottom cover, which further enhances the sealing effect.

In summary, the seals of the chemiluminescence immunoassay analyzer are a key component to ensure the stability of the reagents and the accuracy of the experimental results. Through the compact design, the seals not only improve the quality of reagent preservation but also improve the efficiency of the analyzer and the reliability of the results.
