Open-air Shakers (General)


Microprocessor PID control.
- Intelligent speed controller enables reproducible results.
Shaking speed calibration enables matching the displayed rpm to the reference point.
Competitive high shaking speed up to 500 rpm.
Orbital shaking motion in various diameter.
- 19.1mm or 25.4mm for OS-4000
- 25.4mm for OS-7100
- 50.8mm for OS-7200
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. (for OS-7100/7200)
- Equipped with a maintenance-free BLDC motor to generate smooth, quiet, uniform, and yet powerful shaking motion. (for OS-4000)
Best effort run function intelligently manages its rpm to keep shaking even workload is out of its capacity.
- Automatic shaking speed adjustment in case of excessive workload such as unbalanced load placement, unusual vibrations caused from unstable floor or external shock.
Pleasant test environment by the smooth acceleration and deceleration control.
- Smooth start and smooth stop function prevent chemical spills from flasks or test tubes.
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.
Built-in RS-232 port and USB port for external control and data collection.
Variety of accessories are available to meet application demands.

Automatic run after power interruption.
Shaking speed deviation alarm.
Over-current protection, Stalled platform check. (stalled platform check is for OS-4000)
CSA only for OS-4000.
