This low-profile, four-position stirrer offers three stirring levels and programmable memory profiles.

Microprocessor controls offer precision and reproducibility without internal heat build-up. Stirring functions include reverse and interval stirring for applications ranging from gentle stirring for cell culture to aggressive mixing for viscous polymers. Stirrer can be used with three 1 L spinner flasks or four 1 L flasks and beakers with a maximum sample weight of 10 kg (22 lbs.). Programmable mode includes speed, ramp rate, stir direction, time (including pause), and power level in up to nine distinct steps. Up to four stirring programs can be saved.

Selectable ramp rates: 5 to 300 rpm/sec.
