Flasks are the preferred vessel for long term cultivation or large-scale expansion of cells, providing the best protection against contamination. The ergonomic design with angled neck and wide opening allows easy access to the growth surface by pipettes or cell scrapers. Workflow safety is combined with facilitated and ergonomic access to your cells in the Cell Culture Flasks. They are available in three sizes: T25, T75 and T175 with TC treated. Vented caps with innovative air filter technology or plug–seal caps with arrested position to prevent undesired closing are the two closing options.
