CELLTREAT 229341 T-75 Tissue Culture Flask with Vent Cap — Sterile, 100/Case

The CELLTREAT 229341 is a sterile, tissue culture-treated T-75 flask designed for adherent cell culture applications. With 75 cm² of flat, uniform growth surface, a 250 mL total capacity, and a 0.22µm hydrophobic membrane vent cap for proper gas exchange, this flask is built for demanding, reproducible cell culture work in academic, biotech, and pharmaceutical laboratories.

Manufactured under the most stringent conditions, CELLTREAT tissue culture flasks include a 100% integrity test to assure reliability. Class 100,000 clean room production, USP Class VI virgin polystyrene, and ISO 9001 quality management systems all contribute to consistent cell culture performance. Growth surfaces are flat and free from striations to maximize usable growth area and optical transparency.

Tissue Culture Treated Surface The tissue culture surface treatment provides a negatively charged hydrophilic surface, resulting in consistent cell attachment. This uniform surface is ideal for a wide range of adherent cell lines and primary cells requiring reliable, repeatable attachment.

Canted Neck & Large Opening Design The large opening and canted neck design with moderate angles provide easy access to the entire flask surface — particularly convenient when using cell scrapers for passaging. The stable flat base allows filling with the flask standing upright, reducing spills during media changes.

0.22µm Hydrophobic Vent Cap The vent cap features a 0.22µm PTFE hydrophobic membrane that maintains sterility while allowing continuous gas exchange between the flask interior and the incubator atmosphere — essential for CO₂-buffered cell culture systems.

Durable Construction & Smart Stacking Thick, durable polystyrene walls protect cultures during handling. The molded interlocking T design enables stable, secure stacking with other CELLTREAT flasks (75, 182, and 300 cm² and 250, 600, and 850 mL formats), maximizing incubator space efficiency.

Lot-Tracked & Easy to Store Each flask is printed with its lot number and expiration date for full traceability. Packaged in convenient zip-closure resealable bags (5 flasks per bag, 20 bags per case) — a practical, mess-free alternative to folding and re-taping open bags.
