1. Product Overview
The Aibona OM-type sealing ring vacuum sealing flange viewport is a highly reliable observation window assembly specially designed for vacuum glove boxes and inert atmosphere glove box systems. Adopting an OM-type elastic sealing ring structure, paired with high-strength metal flanges and high-light-transmittance window materials, the product delivers excellent gas tightness while enabling clear and stable observation of experimental processes inside the chamber. Suitable for long-term vacuum or inert atmosphere environments, this viewport meets application requirements including 2D material transfer, semiconductor processes, vacuum coating, material growth, and water-oxygen-sensitive experiments. It serves as one of the standard and customized core components for Aibona glove box systems and vacuum chambers.
II. Product Features
(1) OM-type sealing ring structure
Adopts the mature and reliable OM-type sealing ring design with uniform stress distribution and stable sealing performance, suitable for working conditions of frequent start-stop and long-term operation.
(2) High-transmittance observation window
Made of borosilicate glass or quartz glass, featuring high light transmittance and clear imaging, it meets the requirements for visual inspection and assisted observation by microscope systems.
(3) Excellent vacuum sealing performance
Designed for low leakage rate, it can satisfy the application requirements of high-purity inert atmosphere and medium-to-high vacuum in glove boxes.
(4) Standard flange mounting
Highly compatible with glove box and vacuum cavity structures for easy installation, maintenance and replacement.
(5) Outstanding corrosion resistance and environmental stability
Suitable for organic solvents, water and oxygen sensitive materials and complex experimental environments.
