When designing a photobioreactor, the most common transparent materials are PMMA and GLASS!

We used PMMA for many years, and it is still relevant for certain applications, for example it is cheaper, and in teaching environments, where its resistance to breakage is an advantage.

However, we now equip all our photobioreactors with GLASS tubes only !

Why ?

• For its higher temperature resistance, ideal for CIP processes and efficient cleaning,
• For its lower surface roughness, reducing algae and mineral adhesion,
• For its better chemical resistance, especially to acids, bases and disinfectants,
• For its long-term optical stability, maintaining light transmission for optimal photosynthesis,
• For its durability over time, as the quality remains intact even after years of cultures,

Over time, GLASS provides more stable performance, better durability, and more consistent culture conditions compared to plastic alternatives.
