Greiner Cellstar Cell Culture Flask 250ml 75 cm² with Filter Cap

The CELLSTAR® Standard Cell Culture Flask with Filter Cap is designed to support reliable and reproducible adherent cell culture workflows across research, biotechnology and laboratory environments. Manufactured by Greiner Bio-One, this sterile culture flask features a tissue culture-treated surface that promotes consistent cell attachment and growth, making it suitable for routine cell culture applications where dependable performance is essential. 

This larger flask format provides additional culture capacity while maintaining the practical handling features expected from the CELLSTAR® range. The canted neck design supports easier access to the growth surface during cell seeding, media changes and harvesting, while helping to reduce the risk of spills during routine handling. The integrated filter cap enables continuous gas exchange without the need to loosen the cap during incubation, helping maintain a protected culture environment and reducing contamination risk. 

Manufactured from optically clear polystyrene, the flask allows easy microscopic observation and visual monitoring of cultures throughout incubation. Its clear construction supports efficient inspection of cell morphology, confluence and media condition, helping researchers make timely workflow decisions. Side graduation markings provide convenient visual guidance when adding or removing media, contributing to more efficient day-to-day laboratory processes. 

As part of the Greiner Bio-One CELLSTAR® range, this flask is manufactured to stringent quality standards and undergoes controlled testing to support consistency across laboratory applications. It is sterile, non-cytotoxic and free from detectable DNase, RNase, human DNA and pyrogens, helping protect valuable cell lines and maintain experimental integrity. Ideal for laboratories scaling adherent cell culture workflows, this CELLSTAR® flask provides a dependable solution for researchers who require sterility, ease of handling, reliable gas exchange and reproducible cell culture performance in a larger flask format.
