Achieve maximum adhesion for a broad range of cell types with Thermo Scientific™ Nunc™ Cell Culture Treated Flasks. These flasks receive the proprietary Nunclon™ Delta surface treatment to ensure consistent cell growth. Low profile design maximizes incubator space. Flasks feature volume graduations printed and molded on both sides and slightly angled side walls allow for complete viewing under a microscope.

Vented caps feature a set vent position that produces a finger-felt positive stop when fully open for gas exchange and the Y on the cap provides a visual indication of the vent/close position when stacked in incubators. Filtered caps allow constant airflow and minimize chances of contamination.

Well-defined, hydrophobic filter membrane offers continuous venting with consistent gas exchange and no lot-to-lot variation. Chemically robust membrane meets USP class VI standards and is produced without animal-derived substances.
