3.2 General overview
The Innova 44/44R stackable incubator and incubator refrigerated shakers are large-capacity
orbital shakers that utilize a triple eccentric counter-balanced drive mechanism. They provide
horizontal plane rotary motion in either a 2.54 cm (1 in) or a 5 cm (2 in) diameter circular orbit,
depending on the model. A Proportional/Integral (PI) microprocessor controller with
instantaneous digital feedback controls the speed over the entire speed range.
The Innova 44R provides temperature control from 20 °C below ambient (as low as 4 °C) to 80
°C, and the Innova 44 from 5 °C above ambient to 80 °C. Naturally, both these ranges depend
on relative humidity and other ambient factors, as well as the options installed in the unit.
Ambient temperature is measured at one meter from the exterior of the unit.
Erlenmeyer flasks (up to 5 liters in size) as well as a wide variety of tubes and plates can be
accommodated using the New Brunswick shaker accessories described in a later section
(see Accessories on p. 58). These are easily accessed on slide-out platforms.
The Innova 44/44R may be operated in the following ways:
• Continuously: at a set speed and temperature, until user intervention.
• In a timed mode: run at a set speed, time and temperature for a period of up to 99.9 hours,
after which the shaker automatically shuts off.
• Via the shaker’s programmable controller: run through multiple temperature and speed
changes for an extended period of time.
For more details on these various modes of operation, (see Operation on p. 37).
For safe operation, the Innova 44/44R shakers are designed with a safety switch that
automatically stops the shaker mechanism when the door is opened.
