Designed for the growth of suspension and microcarrier cell cultures, these stirrers work with cell culture flasks and other vessels designed for slow magnetic stirring. Also ideal for use in incubators, CO2 incubators, or cold rooms (–10 to 60°C). Precise, microprocessor control accurately maintains speed from 1 to 120rpm with slow start/stop feature, and a ramping feature slowly brings samples to set speed. Stirrers feature a powerful magnet for strong coupling to impellers or spin bars, an efficient drive motor that eliminates heat transfer to sample, spill-resistant housing, and a cast metal base for durability and added stability. The large top plate with position indicators provides a white reflective surface and the low profile design takes up less space and easily fits into most incubators. The one-position stirrers feature an aluminum top plate; the four-position stirrers feature a glass-filled nylon top plate.
