The sterile isolator is a highly sterile and continuously effective operational space achieved through sterile isolation technology, which can significantly reduce contamination from microorganisms and various particles, thereby enhancing the accuracy of sterile testing. There are two simple purposes for using a sterile isolator: one is to protect the samples from environmental contamination, including contamination from operators and testing environments. The other is to safeguard operators from exposure to toxic and harmful substances. The application range of sterile isolators is very wide, especially in the production of sterile pharmaceuticals. By applying sterile isolators in sterile pharmaceutical production, not only is the quality of the drugs ensured, but costs are also reduced.
Sterile IsolatorThe inflatable seal is embedded in the groove of the door leaf frame. Its working principle is as follows: when the door is opened, the inflatable seal deflates and contracts within the groove. When the door is closed, the inflatable seal inflates and expands, creating a tight seal between the door leaf and the door frame, while also securely locking the door.
Seal stripCan be used independently or in combination with multiple sets, featuring single-door control or multi-door interlocking capabilities, ensuring safety and reliability. Widely applied in high-level biosafety laboratories, disinfection rooms, isolation rooms, and other health and safety fields.

Product Advantages:
Utilizes imported high-density inflatable sealing strips for enhanced sealing performance.
Stainless steel round observation viewport.
Interlock to prevent incorrect operation.
The door frames are designed with matching joists for easy installation.
The door panels feature a concentric circle design at the four corners, ensuring enhanced airtightness.
This inflatable silicone rubber seal and its sealing structure feature simplicity in design, ease of installation, excellent sealing performance, and the ability to achieve self-sealing in both axial and radial directions. The outer edge of the inflatable seal has a guiding positioning ring, and when the upper and lower lips on the inner edge are closed together, they form a complete closed hollow circular ring. Once the hollow circular ring is filled with high-pressure gas (or liquid) inside a pressure vessel, it expands outward, developing self-tightening properties in both axial and radial directions. The greater the pressure inside the pressure vessel, the stronger the self-tightening and the better the sealing.
Qingtu Rubber specializes in the production of inflatable sealing rings for pressure vessels. Over the years of operation, we have accumulated extensive experience in the development and production of inflatable sealing rings, assisting numerous manufacturers in solving the sealing issues of open-type pressure vessels. When it comes to inflatable sealing, we are the experts. Please feel free to call for consultation and customization.
