Extended pH stability with high performance

Take a look inside

Gemini Two-In-One Technology™

 

Twin™ Technology

 

During the final stage of silica manufacturing a unique silica-organic layer is grafted to create a completely new composite particle. Since the internal base silica is unaltered by this manufacturing process, the particle retains its mechanical strength and rigidity along with excellent efficiency, while the silica-organic shell protects the particle from chemical attack.

 

NEW: With the new Gemini-NX, Phenomenex even improved this performance.
