General Description
The Innova 3100 is a shaker that incorporates a triple eccentric counterbalanced drive
to provide horizontal plane rotary motion in a ½ inch (12.7 mm) circular orbit. A
Proportional/Integral (PI) microprocessor controller with instantaneous digital
feedback controls the speed over a range of 25-400 RPM. It also provides temperature
control over a range of 5
°C above ambient to 80°C. For lower temperatures an
optional water bath cooling coil is available.
The shaker may be operated either continuously or in a timed mode via a
programmable timer for shaking periods of 0.1 hour to 99.9 hours.
The Innova 3100 is equipped with audible and visible alarms which are activated when
an alarm condition exists as follows:
• The end of a timed run
• Deviations of shaking speed or temperature outside of tolerance limits
• Low water level
• Water overflow
A wide variety of platforms can be used with the Innova 3100. Dedicated platforms
are available for a variety of flask sizes. A Universal platform and test tube racks are
also available. (See Chapter 7 for accessories.)
The Innova 3100 has a built-in water level control system which is infinitely adjustable
over a wide range. To compensate for evaporation, water is automatically replenished
to the preset level.
Additionally, the Innova 3100 has analog outputs for a chart recorder that will record
speed and/or temperature. See Chapter 5 for recorder adaptation.
See Figures 1 and 2 below for the front and rear views of the Innova 3100.
