CL-F025P 25 cm² Untreated Cell Culture Flask (CAT#: STEM-AL-3053-ZJF)

CL-F025P is a sterile polystyrene cell culture flask configured for suspension and non-adherent cell culture. Its untreated internal surface avoids the attachment-promoting treatment used for adherent culture vessels. The flask provides a flat internal area for controlled cell cultivation and observation. An angled neck and broad opening allow pipettes or cell scrapers to reach the vessel interior. The transparent body supports routine visual inspection of culture conditions. The inclined sidewall geometry makes the growth area easier to view under a microscope. A plug cap provides a closed closure configuration for handling and transport. The raised cap perimeter helps maintain stability when flasks are stacked. The vessel is supplied ready for contamination-conscious laboratory cell culture workflows.
