Silicone Test Chambers

Saint-Gobain silicone test chambers are precision-molded components specifically designed to meet the stringent requirements of the ophthalmic surgical market. These test chambers are used as a critical accessory in the setup and validation of phacoemulsification systems prior to surgery. Our test chambers are molded from high-purity, 40-durometer medical-grade silicone. They are fully compliant with USP <88> Class VI and Plastic Class VI biocompatibility standards.

Functional Purpose in Surgical Setups

The silicone test chamber is typically used as part of the pre-procedure testing protocol for ophthalmic surgical systems. It is specifically designed to assess and verify the pressure integrity and performance of the handpiece within a phacoemulsification system before the start of an eye surgery. By providing a consistent and controlled environment for system checks, the test chamber helps ensure patient safety and device functionality.
