Cell culture flasks, double side arm, Celstir®

Supplier: Wheaton
Borosilicate glass flask, PTFE and glass impeller assembly, PTFE and silicone lined top cap

  • Adjustable paddle blade impeller allows better mixing
  • Impeller does not protrude through the top cap, thereby maximising incubator space and reducing the risk of contamination
  • Addition of the bottom dimple to flasks 125 ml and larger improves circulation and reduces the accumulation of cells in the centre of the flask
  • Flasks 500 ml or larger have a 45 mm side arm to be used as an air vent, media inlet or outlet, innoculation port, pH probe inlet, or other application

Double side arm Celstir® flasks are ideal for microcarrier and suspension cultures such as insect cells, hybridomas and adapted cell lines.
