The Wheaton Magna Flex Spinner Flasks feature a flex-type, bulb-shaped glass impeller that rotates from a fixed position above liquid level around an indentation in the base of the flask. Primarily designed for use with microcarrier cultures, this unique stirring system increases stirring efficiency and provides a gentle, even circulation throughout the flask while keeping the beads in suspension. All flasks have been proportioned to provide a head space ratio of 1:1 or greater. A removable stainless steel pin immobilizes the impeller during handling or decanting to prevent damage to cells or microcarriers. Sizes 500 mL and larger can accommodate Vented Cap Cat. No. 1088655.
• Designed for use with microcarrier cultures
