Double Sidearm CelStir Spinner Flask
Starting at $60.80
The Celstir Spinner Flask features an adjustable paddle blade impeller for better mixing. The addition of the bottom dimple to flasks 125 mL and larger improves circulation and reduces the accumulation of cells in the center of the flask. Celstirs provide maximum surface interface between culture and flask atmosphere. Use the Celstirs for microcarrier and suspension cultures such as insect cells, hybridomas, and adapted cell lines. The entire unit may be autoclaved at 121°C for 20 minutes. Celstirs are made from Wheaton 33 low extractable borosilicate glass that conforms to ASTM Type I, Class A and USP Type I requirements.
Graduations: Sizes 125 to 1000 mL are graduated in 50 mL increments; sizes 3000 to 8000 mL are graduated in 500 mL increments; sizes 25 mL and 50 mL are non-graduated.

· Sidearms for 500 mL - 8 L flask allow vented caps which enables the flask to “breathe” while protecting from contamination
