Microbial invasion sealing instrument

DRK134WMicrobial invasion sealing instrumentSuitable for sealing tests of flexible packaging in industries such as food, pharmaceuticals, medical devices, daily chemicals, electronics, etc. This device can perform positive pressure testing and negative pressure testing. Experiments can effectively compare and evaluate the sealing processes and sealing performance of various samples, providing scientific basis for determining relevant technical indicators. Sealing performance tests can also be conducted on specimens that have undergone drop and pressure tests. It is also professionally applicable for the quantitative determination of sealing strength, creep, heat sealing quality, as well as the burst pressure and sealing leakage performance of various sealing edges formed by various heat sealing and bonding processes, such as soft and hard metal, plastic packaging, sterile packaging, etc. Microbial invasion tests and the quantitative determination of sealing performance of various plastic anti-theft bottle caps, medical humidification bottles, metal drums and caps, as well as the quantitative determination of overall sealing performance, pressure resistance strength, cap connection strength, release strength, heat sealing edge sealing strength, tie strength and other indicators of various hoses; At the same time, it is also possible to evaluate and analyze the compressive strength, burst strength, and other indicators of the materials used in flexible packaging bags, as well as the torque sealing index of bottle caps, the connection and detachment strength of bottle caps, the stress strength of materials, and the sealing, compressive strength, burst resistance, and other indicators of the entire bottle body. Compared to traditional designs, it truly achieves intelligent testing: presetting multiple sets of experimental parameters can greatly improve detection efficiency.

RK134WMicrobial invasion sealing instrumentWorking principle: Microbial invasion test method, also known as microbial challenge method, is a common sealing integrity testing method, usually conducted simultaneously with simulated filling. By simulating the filling of the culture medium according to the simulation filling verification plan, followed by plugging and capping, the visual inspection is qualified. After sterilization in the validated sterilization cabinet, the sealing surface of the container is immersed in a high concentration of bacterial solution, so that the culture medium in the sample container fully contacts the inner surface of the seal. The neck of the sample and the outer surface of the seal should be fully immersed in the bacterial suspension. After soaking for a certain period of time, it is taken out and regularly cultured to check for microbial invasion and determine the integrity of the container sealing system. At the same time, a positive control test needs to be conducted to confirm the growth promoting ability of the culture medium. Vacuum or overpressure challenge conditions are usually used in testing.
