Cell culture flasks with standard screw cap/plug seal (without filter).

• Improved cell adhesion through physical surface treatment
• Canted neck
• Graduation on both sides
• Sterile and user-friendly packaging
• 25 cm^², 75 cm^², and 175 cm^² growth areas
• High and flat design of the 175 cm^² cell culture flask for variability of media volume

All Greiner Bio-One cell culture flasks are made of high-grade polystyrene

Flasks are free of detectable DNase, RNase, and human DNA and are non-pyrogenic.

The 550 mL flask has a low profile design. The 650 mL flask has a high profile design.

For adherent cell culture, the surfaces of the standard cell culture flasks are physically surface-treated to improve cell adhesion and proliferation. The special design of the cell culture flasks makes it possible to efficiently reach the cell lawn with a cell scraper, whilst still providing optimal access with a pipette. The special neck design reduces the risk of wetting the inside of the cap with medium, thus providing additional protection against contamination. The stacking rim on the top of the flasks ensures firm standing and easy stackability in the incubator. Both sides have a printed graduation for easier filling.
