Greiner Cellstar Cell Culture Flask 550ml 175 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. 

Designed for larger-scale adherent cell culture applications, the CELLSTAR® low-profile flask combines increased culture capacity with ergonomic handling features that support efficient laboratory workflows. The specially engineered flask design provides excellent access to the cell layer with both pipettes and cell scrapers, while the high-profile neck helps reduce wetting of the inside of the cap, providing additional protection against contamination. The integrated filter cap enables continuous gas exchange during incubation, helping maintain optimal culture conditions while minimising 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.
