Maximum speed up to 500 rpm (up to 30.8 lb load capacity)
-
400 rpm at loads up to 46.3 lbs
-
Best Effort Run function intelligently adjusts RPM to maintain stable shaking when workload approaches capacity
Precision Control & Smooth Operation
-
Microprocessor PID control with shaking speed calibration
-
BLDC motor provides quiet, vibration-reduced, maintenance-free operation
-
Smooth acceleration and deceleration minimizes sample disturbance and spillage
-
Low-profile design reduces vibration and bench movement at high speeds
