These graduated, canted-neck flasks are manufactured in an aseptic, fully automated facility from high-quality virgin polystyrene resin to ensure superior optical clarity.

• High-quality virgin polystyrene construction
• Superior optical clarity
• Hydrophobic surface
• Ideal for suspension cultures and hybridoma

Flask design makes it possible to efficiently reach the cell lawn with a cell scraper, while still providing optimal access with a pipet

All flasks are integrity tested to provide uniform growth and proliferation, and are sterilized by radiation. Flasks are nonpyrogenic, noncytotoxic, and free from DNase, RNase, and human DNA.

Flasks have a hydrophobic surface, ideal for suspension cultures and hybridoma. The 550 mL flask has a low profile design. The 650 mL flasks have a high profile design. Red filter screw cap has a capillary 0.2 µm pore diameter membrane and hydrophobic inner surface. Standard screw cap has a ventilation position.
