Powerful driving system with a durable body structure increases shaking capacity
Suitable for larger or heavier workloads requiring 
accurate and reproducible results.


Control Panel

Safety Features 

  • Worry-free operation.
    Automatic shaking speed adjustment in case of excessive 
    workload such as unbalanced load placement, unusual 
    vibrations caused from unstable floor or external shock. 
  • Automatic run is available with non-volatile set point 
    memory after power interruption, indicated in control display.
  • Audible/Visible alarm activated by shaking speed deviation.
  • Shaker protection system against over-current, stalled 
    platform check. (Stalled platform check is only for OS-4000)

Operating Features

  • Microprocessor PID control.
    - Intelligent speed controller enables reproducible results.
  • Shaking speed calibration enables matching the displayed rpm to the reference point.
  • Various speed ranges up to max. 500 rpm.
  • Timer range: 1 min. to 999 hr 59 min.
  • Orbit diameter.
         19.1mm (Standard) or 25.4mm for OS-4000
         25.4mm for OS-7100
         50.8mm for OS-7200 
  • User friendly control panel.
    Lab Companion’s unique VFD-bright, clear, easy to read. 
    Durable membrane touch switch and control knob.
  • Speed is basically set and displayed in increments of 1 rpm.   
  • Also speed increment interval can be set among 1, 5, 10 rpm according to users preference.
  • Built-in RS-232 port and USB port for external control and data collection.  

Constructional Features

  • Wide speed range even with heavy workload.
    -  Ideal DD(Direct Drive) Brushless Motor and triple cam system 
    support heavy load, quiet, maintenance free operation 
    and deliver high torque at high speeds and smooth 
    rotation. (only for OS-7100/7200)
    -  Equipped with a maintenance-free BLDC motor to 
    generate smooth, quiet, uniform, and yet powerful shaking 
    motion.  (only for OS-4000)
  • Repetitive task can be easily performed as the platform stops where it starts. 
    - Stopping the shaking plaNorm always at the same position 
    is highly benefcial for automated dosing or sampling process.
  • Pleasant test environment by the smooth acceleration and deceleration control.
    -  Smooth start and smooth stop function prevent chemical 
    spills from Vasks or test tubes.
  • Low-profile design minimizes vibration or sliding caused by the high speed shaking motion.
  • Various accessories.
