Wheaton™ Borosilicate Glass Replacement Impeller

Magna-Flex™ microcarrier spinner flasks feature a flex type, bulb shaped glass impeller which rotates from a fixed position above the liquid level around an indentation in the base of the flask. Made of borosilicate glass with two large sidearms and screw cap closures for easy sampling. 500mL and larger units have 45mm sidearms to be used as convenient vents and ports. All flasks provide a headspace ratio of 1:1 or greater to provide maximum surface interface between culture and vessel atmosphere. A removable stainless steel pin immobilises the impeller during handling. Replacement glass impeller assemblies are available for all flasks. For use with microcarrier cultures.
