The Excella™E-2 Classic Platform Shaker is a portable benchtop shaker utilizing a UniCentric™
counterbalanced drive to provide horizontal plane rotary motion in a ¾-inch (1.9 cm) circular
orbit. A Proportional/Integral (PI) Microprocessor controls the speed over a range of 50-400 rpm.
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 E-2 is equipped with an audible alarm which is activated when an alarm condition exists, as
follows:
• The end of a timed run
• Deviations of shaking speed
A wide variety of platforms can be used with the E-2. Dedicated platforms are available for a
variety of flask sizes. Universal platforms, utility trays, utility carriers and test tube racks are
also available.

NBS flask clamps are used on a variety of shaker platforms. Flat head screws of different
lengths and thread pitch are used to secure the clamp. To identify the proper screw for your
shaker application by reference to the head style, consult Table 1 below, find the proper
screws and set the others aside.
Table 1: Clamp Hardware Application Chart
No matter what size the clamp, use these screws to fasten them to your platform:
