With the super low cell attachment surface, Thermo Scientific™ Nunclon™ Sphera™ Flasks consistently promote 3D spheroids and organoids culture, aiding you in cancer spheroid formation and stem cell differentiation for disease modeling and drug screening.

Significant qualities of the Nunclon Sphera culture surface:

Optimizing spheroid formation
  • Allows cells to grow in suspension with virtually no cell attachment
  • Supports many different cell types and their ability to generate spheroids
  • Enables consistent, repeatable cell growth
Growing 3D cancer cultures
  • Minimizes variability and supports the consistent formation of cancer spheroids that simulate the 3D structures of tumor growth, providing a better model system for studying tumor cell progression and efficacy of anticancer agents in vitro
Promoting formation of embryoid bodies (EB)
  • Demonstrates superior quality for embryoid body formation of pluripotent stem cells with minimal spontaneous differentiation
  • Resultant cells able to differentiate into all three germ layers


Animal origin-free; nonpyrogenic, endotoxin <0.5 EU/mL; USP biological reactivity class VI; SAL 10-6
