•
Press RUN/STOP to start the unit. The RUN LED will blink until the unit
attains full set speed.
•
During the CYCLE ON time, the CYCLE ON light and the CYCLE RPM light
will alternately blink, and display the remaining CYCLE ON time, and the set
CYCLE RUN speed.
•
Once the CYCLE ON time counts down to ZERO, the unit RUN light will blink
as the unit ramps down to a stop.
•
When in the CYCLE OFF time, the CYCLE TIME OFF light and CYCLE
COUNT lights alternately blink, showing the remaining CYCLE OFF time, and
remaining cycles to be run.
•
Once the cycles are complete, the unit will run at its set final RUN RPM
speed.

Two Speed Stirring
The Biostir
®
can be set to run in two speed stirring mode, where the unit will run
at a set stirring speed for a programmed time, and then run at a final constant
speed after that.
This type of stirring may be especially helpful in cell culture applications during
initial seeding where cells may need a slow stirring time to reach maturity, and
then a faster running speed for the remainder of the growth time.
Below are typical cycle stirring profiles, showing an initial stirring speed for a set
time, and then the unit ramping to a final constant speed. The upper profile
shows the unit ramping to a higher speed, while the lower profile shows the unit
ramping to a slower speed.
