1.1 General Description
The Innova 4340 Digital Illuminated Refrigerated Incubator Shaker will provide
you with reliable and maintenance-free operation which is characteristic of all
NBS shakers. The Innova 4340 is among the newest generation of NBS shakers. It
incorporates a variety of state-of-the-art components and features to permit the
precision operation necessary for your exacting scientific experiments.
The Innova 4340 shaker has a triple eccentric counterbalanced drive to provide
horizontal plane rotary motion in a 1 inch (25.4 mm) circular orbit. A
Proportional/Integral (PI) Microprocessor controller with instantaneous digital
feedback controls the speed over a range of 25-500 rpm. It also provides
temperature control over a range of 4
°
C to 60
°
C (at 20
°
C ambient). The internal
chamber is 34 ¾ inches (88.3 cm) wide, 22¼ inches (56.6 cm) deep, 19¼ inches
(48.9 cm) above the platform and will accept flasks up to 4 liters. It is equipped
with a foot pedal lid lift assist.
The Innova 4340 has an illuminated cover that allows up to six grow lamps to be
operated manually or by a programmable electronic timer. An auxiliary channel
of the electronic timer may be used to program the temperature controller to
switch to an alternate setpoint at desired times.
The shaker may be operated either continuously or in a timed mode for shaking
periods of 0.1 to 99.9 hours via the main control microprocessor.
The Innova 4340 is equipped with audible and visible alarms that 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
A wide variety of platforms can be used with the Innova 4340. Dedicated
platforms are available for a variety of flask sizes. A Universal platform and test
tube racks are available
(see Section 9 for Accessories) .
Additionally, the Innova 4340 has analog outputs for a chart recorder that will
record speed and/or temperature. (
See Section 7, Service, for Recorder
Adaptation.)
