Wheaton® Double Sidearm Celstir® Spinner Flasks

By Wheaton Science Products
Wheaton® Double Sidearm Celstir® Spinner Flasks

Use the Wheaton® Celstir® for microcarrier and suspension cultures such as insect cells, hybridomas, and adapted cell lines. The Celstir® features an adjustable paddle blade impeller for better mixing. The impeller does not protrude through the top cap, thereby maximizing incubator space and reducing the chance for contamination. The addition of the bottom dimple to flasks 125mL and larger improves circulation and reduces the accumulation of cells in the center of the flask. Units 500mL and larger have a 45mm sidearm to be used as an air vent, media inlet or outlet, inoculation port, pH probe inlet, or for other applications. Flasks provide maximum surface interface between culture and flask atmosphere. All flasks are proportioned to provide a head space ratio of 1:1 or greater. The unit consists of a glass flask, PTFE and glass impeller assembly, and PTFE and silicone-lined top cap. It is designed for use with Wheaton Micro-Stir® magnetic stirrers. The entire unit can be autoclaved.

Sizes 125 to 1000mL are graduated in 50mL increments; sizes 3000 to 8000mL are graduated in 500mL increments; sizes 25mL and 50mL are non-graduated. Flasks are made from Wheaton 33® low extractable borosilicate glass (meets ASTM Type I Class A and USP Type I Standards). Units 500mL and larger can be used with the Vented Cap (Cat.No. 12-W240751).
