In the pursuit of new frontiers in space biotechnology, we have designed an innovative system capable of maintaining cell cultures in a controlled environment, minimizing the adverse effects of microgravity. This development is essential for ensuring the stability of the culture medium and preventing cellular stress, a critical challenge in biological experiments beyond Earth.
Our cell culture bottle design allows for a completely laminar flow at the bottom, preventing turbulence that could affect cell viability. Additionally, it prevents air or carbon dioxide (CO₂) from coming into direct contact with the cells, protecting them from unexpected environmental changes.
How does this system work?
The system consists of two strategically connected chambers:
🔹 Upper cylindrical container: Designed with a screw cap for pouring the culture medium. Its geometry promotes a controlled turbulent flow, enhancing oxygenation and stabilizing pH, ensuring optimal conditions for cell culture.
🔹 Lower rectangular container: Here, the culture medium becomes static, facilitating cell sedimentation without turbulence interference. The connection between the two chambers is made through a helical tube, which regulates the fluid transition in a stable manner.
🔹 Flow regulator with a cylindrical sphere: This key component controls the descending speed of the culture medium, ensuring that internal conditions remain stable and free from unwanted disturbances.
Preventing CO₂ Impact on Cell Culture
One of the main challenges of this design is preventing CO₂ accumulation at the bottom, which could alter the environment and compromise cell viability. To counteract this, we have incorporated three strategic solutions:
✅ System height: A sufficient upper space has been left to ensure CO₂ remains trapped without mixing with the culture medium.
✅ Flow resistance (pressure loss): The tube’s geometry reduces CO₂ descent through the Darcy-Weisbach equation, which shows that the longer and narrower the channel, the greater the resistance to gas movement.
✅ Optimized geometry: The cylindrical structure of the bottle minimizes turbulence and internal convection currents, preventing gas from mixing with the medium and reaching the cells at the bottom.
Durable and Stable Design
To ensure structural stability and prevent weight concentration at connection points, we have incorporated support columns that distribute the load evenly. This prevents fractures and ensures the system maintains its integrity despite the demanding space environment.
🚀 This breakthrough not only advances bioengineering in microgravity but also paves the way for new research in biotechnology and space exploration. Our goal is to revolutionize how we sustain life beyond Earth, enabling cell cultures to thrive in optimal conditions even in the most extreme environments.
The future of space biotechnology is closer than ever!
