With Teflon® Faced Rubber-Lined Caps

In today’s market the Celstir design is the standard flask type for cell culture. Celstir flasks feature adjustable blade impeller for increased aeration and dimpled bottom to prevent the accumulation of cells under the impeller (dimpled bottom on 125 mL size and larger). When used with the Micro-Stir®, which can operate at very low speeds, the Celstir flask provides an optimum environment for most suspension lines, including insect cell cultures. Hybridomas and adapted cell lines can also be grown in these spinner flasks. Sidearms on Magna Flex® and Celstir vessels 500 mL and larger were widened to accommodate monitoring and control devices or media inlet/outlet lines. The Jacketed Double-Sidearm Celstir, complete with water jacket, allows precise temperature control of Celstir contents when operated with a recirculating water bath. The hose connectors accept 1/4 ID tubing. This unit is made from 33® low extractable borosilicate glass (meets ASTM Type I Class A and USP Type I Standards).
