Dual-action shakers

Inquire product

Dual-action benchtop platform shakers accommodate flask up to 6L. with optional dedicated platform


  • Dual-action shaking motion: Orbital / Reciprocating.
  • Microprocessor PID control / Shaking speed calibration.
  • Competitive high shaking speed up to 500 rpm.
  • Shaking motion in various amplitude.
    – 12.7mm or 19.1mm for OS-2000
    – 19.1mm or 25.4mm for OS-3000
    – 19.1mm or 25.4mm for OS-4000
  • Wide speed range even with heavy workload.
    – Equipped with a maintenance-free BLDC motor to generate smooth, quiet, uniform, and yet powerful shaking motion.
  • Best effort run function intelligently manages its rpm to keep shaking even workload is out of its capacity.
  • Pleasant test environment by the smooth acceleration and deceleration control.
  • Low-profile design minimizes vibration or sliding caused by the high speed shaking motion.


  • User friendly control panel.
    – Lab Companion’s unique VFD-bright, clear, easy to read.
    – Durable membrane touch switch and control knob.
  • Easy-set digital timer. (1 min. to 999 hr. 59 min.)
  • Repetitive task can be easily performed as the platform stops where it starts.
    – Stopping the shaking platform always at the same position is highly beneficial for automated dosing or sampling process.
  • 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.
  • RS-232 port and USB port for external control and data collection.
  • Monitor via mobile app anytime, anywhere with LC Connected (mobile monitoring system) connection. (when purchased LC GreenBox)


  • Automatic run after power interruption.
  • Shaking speed deviation alarm.
  • Over-current protection, Stalled platform check.

1) In Orbital Shaking mode, Regarding the maximum controllable RPM and amplitude by weight, the measurement is performed based on the default value.

2) Actual rpm allowable error for set rpm is 1rpm if setting is less than 100 rpm, ±1% if setting is higher than 100rpm.
