WHEATON® Double Sidearm CelStir Spinner Flask
The Double Sidearm CelStir Spinner Flask is engineered for optimal mixing and culture conditions in laboratory environments. Featuring an adjustable paddle blade impeller, this flask provides superior mixing capabilities, ensuring a homogenous solution for your cell cultures. The innovative design includes a bottom dimple for flasks of 125 mL and larger, which enhances circulation and helps minimize cell accumulation in the flask's center, promoting better growth.
Cultures achieve maximum surface area contact with the flask atmosphere, making the CelStir ideal for microcarrier and suspension cultures, particularly for insect cells, hybridomas, and adapted cell lines. The entire unit can be safely autoclaved at 121°C for 20 minutes, ensuring thorough sterilization and reuse without compromising integrity.
