Here we present a protocol for performing reactions in simple reaction vessels under low-to-moderate pressures of CO2. The reactions can be performed in a variety of vessels simply by administering the carbon dioxide in the form of dry ice, without the need for costly or elaborate equipment or set-ups.

Key procedures to optimize the sealing process and achieve real-time monitoring of the metal-to-glass seal (MTGS) structure are described in detail. The embedded fiber Bragg grating (FBG) sensor is designed to achieve online monitoring of temperature and high-level residual stress in the MTGS with simultaneous environmental pressure monitoring.
FAQs
Applied force improves sealing by increasing contact between joined surfaces and compressing the interface. That compression reduces pathways through which fluids or gases could escape, while close surface conformity helps the barrier remain effective during operation. In bioengineering devices, controlling the pressure is therefore important because an insufficient or poorly controlled force can undermine containment and compromise fluid-handling reliability.
Surface conformity and interfacial compression contribute in different but complementary ways. Conformity allows the contacting surfaces to match closely, whereas compression maintains contact at the interface when the system is operating. Together, these features help the seal tolerate the practical demands of fluid or gas containment. Their success can influence whether a device performs consistently across repeated experiments.
Seal performance is not only a containment issue; it can alter the conditions experienced by a bioengineering experiment. Leakage or unreliable fluid handling may change how a microfluidic or organ-on-chip system operates, producing inconsistent results. For this reason, evaluating the barrier's reliability supports reproducibility, while durability determines whether performance is maintained over the intended operation.
Typically, the joined materials are positioned, brought into close contact, and subjected to controlled pressure. The resulting interface is then used within the engineered system and assessed during fabrication or testing for its ability to support containment and fluid handling. This workflow connects assembly conditions with practical outcomes such as leakage prevention and operation in settings where sterility is essential.
Its uses extend across microfluidic devices, biosensors, organ-on-chip platforms, and other biomedical systems that require controlled containment. In these settings, the seal supports fabrication and testing by helping keep fluids or gases where they belong. That capability is especially relevant when sterility, dependable fluid handling, and stable device operation are necessary for meaningful experimental results.
Success can be considered through the barrier's ability to prevent leakage and maintain reliable fluid handling during operation. Researchers can also relate sealing performance to device accuracy, durability, and experimental reproducibility, because weaknesses at the interface may affect each of these outcomes. Testing the seal in the intended system therefore links mechanical performance with experimental usefulness.
