Wheaton* Magna Flex* Microcarrier Spinner Flasks

Flex-type, bulb-shaped glass impeller 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. Borosilicate glass with two large sidearms and screw cap closures for easy sampling. Fully autoclavable. Units 500 ml and larger have 45 mm sidearms used as an air vent, media inlet or outlet, inoculation port, pH probe inlet, etc. 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 125 to 1000 ml are graduated in 50 ml increments. Sizes 3000 to 8000 ml are graduated in 500 ml increments.
