Product Features

1. The soft cabin structure composed of transparent PVC film, with a fully enclosed top structure design, integrates control units, inlet and outlet air systems, air filtration units, etc., making it more beautiful and easy to clean and maintain

2. The system supports two sterile testing methods specified in the pharmacopoeia: membrane filtration method and direct inoculation method. Integrate the pump unit of the bacterial collector directly onto the operating platform

3. The operation cabin and transmission cabin can be used in combination or separately

4. Both the inlet and outlet ports of the cabin are equipped with H14 high-efficiency filters and high-performance centrifugal fans imported from Germany. The airflow mode inside the cabin is turbulent, which can continuously maintain positive pressure

5. The system reserves interfaces and valves for connecting hydrogen peroxide and sterilizers, and uses hydrogen peroxide steam for sterilization internally, achieving a spore killing effect of lg ⁶ on the air and exposed surfaces inside the cabin

6. Aseptic transfer of items can be achieved through various methods, such as docking with steam sterilized transfer bags, transfer chambers with RTP systems, etc

7. The system adopts Siemens PLC control module and touch sensitive color display screen, optimized interface design, fully automated operation of the system, and has a voltage loss alarm function

8. The system is equipped with multifunctional combination interfaces, such as 25mm standard sanitary quick interface, common media (electricity, gas), and verification/detection interfaces, etc
