Standard and Advanced Slow Speed Stirrers are designed for growth of
suspension and micro-carrier cell cultures. Slow Speed Stirrers work with cell
culture flasks and other vessels designed for slow magnetic stirring. Ideal for use
in cold rooms, incubators, or CO
2
incubators (-10°C to 40°C), 20-80% relative
humidity, non condensing environment.
Operating Features:
Low profile design:
Takes up minimal space and easily fits into fume hoods
and most incubators. Spill-resistant housing channels fluids away from internal
components. Cast aluminum base offers durability and added stability.
Glass filled nylon top plate:
Features a chemical resistant, reflective white top
plate surface that is easy to clean (4 position and 10L models).
Aluminum top plate:
Durable aluminum top will not crack or chip. (1 position
models)
Large top plate:
Stirs up to 4 vessels at once with helpful position indicators.
Microprocessor control:
Precisely regulates speed through the entire range.
Stirring function, with continuous duty motor and magnet, maintains set speed even
under changing load or viscosity.
Adjustment knob:
Basic speed control knob with dial markings from 1 to 10
(Standard Series).
LED display:
Touch pad controls with easy-to-read, independent LED displays for
speed and time. Speed is adjustable in 1rpm increments. Timer will display elapsed
time or, when programmed to user defined limit, will shut off unit when time reaches
zero (Advanced Series).
Safety Features:
Speed ramping feature:
Slowly increases speed for improved safety and enhanced
coupling. Avoids splashing, improves spin bar control and provides excellent low
speed control. Efficient drive motor eliminates heat transfer to sample.
Audible alarm:
In timed mode, alarm will sound when time reaches zero.
(Advanced Series)
Operating Conditions:
Units can be run in cold rooms, incubators, and CO
2
environments from -10 to 40°C
(14 to 104°F), maximum 80% relative humidity, non-condensing.
Applications:
Uniform suspensions of cell cultures, hybridomas, or any slow controlled stirring.
