Biostir® Heavy-Duty Magnetic Stirrers
Designed specifically for use with suspended culture flasks, Biostir® Heavy-Duty Magnetic Stirrers have a DC motor that provides uniform speeds from 150 to 1200rpm, ideal for getting good results with cell cultures or small fermentations. A powerful alnico magnet increases efficiency, and exact rpm can be set using the easy-to-read LED display for consistency. The motor runs smooth, reducing heat transfer to the medium being stirred.
Several automatic modes of operation are featured to optimize cell growth while freeing the operator to concentrate on results.Constant Speed Mode begins with a soft start, then accelerates to a constant preset speed.Interval Start Mode uses the soft start and stop to turn the stirrer on and off for a preset number of cycles, then runs the stirrer at a constant speed, which may differ from the intermittant stirring speed.Two-Speed Stirring Mode slowly starts the stirrer to a set speed, then holds that speed for a user-defined period, after which the stirrer softly changes to a final constant speed.
Computer control assures that all modes run the same way every time, ensuring consistently reproducible results. The Biostir can be used in a CO2 atmosphere with noncondensing humidity in temperatures to 122°F (50°C). Maximum flask size: 3L. Two-year manufacturer™s warranty. 120VAC. UL listed, CSA approved. Remote control also available.
