What makes Nunc EasYFlask products so easy to use?

Ergonomic and optically clear thanks to their virgin polystyrene construction, EasYFlask products are designed for convenience. EasYFlask products are offered as either non-treated flasks or Nunclon Delta surface treated flasks, optimized for both adherent cells and suspension cells respectively.

 Why EasYFlask products are the optimal choice for cell culture and scale-up
Neck widthExtra wide neck provides easier access to growth surface with scraper or pipette
Cap opening1/3-turn cap enables one-handed operation and avoids wrist strains
Volume graduationsMolded and printed for easy and quick measurement of growth media
Sterility assurance level (SAL)Sterility assurance of  SAL 10-6 guarantees that no more than one flask out of one million may be non-sterile
Lot-to-lot testing and certification in each caseLot specific testing across four cell lines and primary cells ensures consistency, reproducibility, and reliability of quality; certificate included in each case
Airflow below flaskVented ribs on flask bottom enable optimal temperature equilibration
Robust designThick walls provide robust design for better resistance to mechanical stress
Continuity of surface for scale upThe Thermo Scientific Nunclon Delta surface—for maximum attachment and growth of adherent cultures—is offered across our T25, T75, T175, T225, and T500 flasks, enabling consistency and confidence when scaling up
