These unique flasks offer three times the yield of standard 175 cm² flasks in the same space, making them ideal for intermediate scale-up production. Harvest cells using protein digesting enzymes such as trypsin, collagenase, and pronase. The design of this flask prevents mechanical scraping. Total culture area is achieved by way of the three parallel layers and a straight neck design that works effectively within automation systems. TripleFlask receives the Nunclon™ Delta treatment, a proprietary cell culture surface treatment that offers maximum adhesion for a broad range of cell types.
