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.
