Wheaton 356830 Glass 125mL MagnaFlex Microcarrier Spinner Flask, with 33-430 Screw Caps, 65mm x 155mm

The Wheaton Magna Flex Spinner Flask features 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 500mL and larger can accommodate the Wheaton Vented Cap (Number W240751).
