2.3 Platform Assemblies
Neither the Innova 2000 nor the 2050 can be used without a platform. One must be
purchased and installed on your shaker prior to operation (see Section 4.3 for
installation instructions).
The Innova 2000 can be used with a wide range of NBS 11” x 13” (28 cm x 33 cm)
platforms, which will accept a variety of clamps for flasks, test tubes, etc. For details,
see the listing in Section 7.1.
The Innova 2050 can accommodate an even wider range of NBS 12” x 16” (30.5 cm x
40.6 cm) platforms, which will accept a variety of clamps for flasks, test tubes, etc.
For details, see the listing in Section 7.2.
2.4 Heavy Duty Construction
2.4.1 Bearings
Innova shakers employ sealed lubricated ball bearings of the highest quality.
Sealed bearings minimize the generation of airborne particulates that could be
disadvantageous in clean rooms or controlled environment areas. These
bearings require
no maintenance .
2.4.2 Motor
Innova 2000 and 2050 shakers use a three-phase brushless ball bearing DC
motor. This low profile motor provides high torque along with quiet, efficient
operation and low maintenance. The motor has a rating of 1/20 horsepower.
2.4.3 Triple Eccentric Drive
The patented triple eccentric drive used in all Innova shakers employs the
same proven technology that has driven New Brunswick Scientific’s shakers
for over 30 years.
The drive mechanism utilizes a counterweight system to stabilize the rotary
motion produced during operation. When the workload moves in one
direction, opposing forces are generated to stabilize the shaker. This action
will help eliminate the problem of “walking” which may occur with less
precisely balanced instruments. Vibration is minimized and the life of the unit
is extended.
