Analysis of Bubble Problems in Serum Separation Gel: A Dual Perspective Study of Process and Raw Materials
2026-01-30
In the field of medical testing, separating gel collection tubes is an important tool for sample collection and preservation, and its quality directly affects the accuracy of the test results. However, in actual production and application, the problem of bubbles in serum separation gel often occurs, becoming a major hidden danger affecting product quality. This article will deeply analyze the reasons for the generation of bubbles in separation glue from two aspects: production and processing technology and raw materials, and propose corresponding solutions.
The hidden danger of bubbles in production and processing technology
1. Bubbles mixed in during the gluing process
Adding glue is the first step in the production of separated glue collection tubes, and it is also the stage where bubbles are most easily mixed in. During the gluing process, due to improper operation or equipment limitations, air may inadvertently mix into the separation glue. These small bubbles are often difficult to detect in their initial state and almost indistinguishable to the naked eye. However, when negative pressure is applied to the blood collection tube, the pressure difference between the inside and outside increases, and the originally small bubbles gradually expand and grow until they reach an observable level. At this point, people often mistakenly believe that bubbles are "regenerated", but in fact, these bubbles have existed since the addition of glue, but have not been discovered due to their small volume.
Solution strategy: In response to the problem of bubbles during the gluing process, enterprises should optimize the gluing process, adopt advanced gluing equipment, ensure a smooth and continuous gluing process, and reduce the chance of air mixing. At the same time, strengthen the control of the production environment, maintain the cleanliness and dryness of the production area, reduce the content of dust and moisture in the air, and further reduce the possibility of bubble generation.
Bubble formation during irradiation sterilization process
Radiation sterilization is an indispensable part of the production of separated rubber blood collection tubes, which uses the energy released by electron beams or gamma rays to kill microorganisms and ensure the sterile state of the product. However, the amount of energy released during the irradiation process, i.e. the irradiation dose, directly determines the sterilization effect and stability of the product. Insufficient irradiation dose may lead to incomplete sterilization; Excessive irradiation dose may cause damage to the product structure, such as cross-linking and curing, while releasing a large amount of heat energy. If these heat sources are not eliminated in a timely manner, bubbles will form inside the product.
Solution strategy: In response to the bubble problem during irradiation sterilization, enterprises should strictly control the irradiation dose, accurately calculate and set appropriate irradiation parameters based on the characteristics of the product and sterilization requirements. At the same time, optimize the cooling system of the irradiation equipment to ensure that the generated heat can be promptly dissipated during the irradiation process, avoiding bubbling caused by heat accumulation. In addition, regular maintenance and calibration of irradiation equipment to ensure it is in optimal working condition is also an effective means of reducing bubble generation.
2, The influence of raw material selection on bubbles
In addition to production and processing technology, the selection of raw materials is also an important factor affecting the generation of bubbles in the separation gel. High quality raw materials are the foundation for producing high-quality separation adhesives. If there are impurities or moisture in the raw materials, these impurities may become nucleation sites for bubbles during the gluing or irradiation process, promoting the formation and expansion of bubbles. Therefore, when selecting raw materials, enterprises should strictly control the quality to ensure that the purity and quality of the raw materials meet the production requirements.
