Ohaus SHHD4525DG & SHHD4550DG Heavy Duty Orbital Shaker, 24″ x 24″ Tray-100 LB Capacity

Heavy Duty Orbital Shakers

• Ready for your lab—all models include a tray and rubber mat and can be customized with over 70 accessory options.

• Rely on the digital shakers’ exclusive Accu-Drive shaking system for exceptional speed control, accuracy and durability. All models feature a maintenance-free motor for long-term use.

• Protect your samples.

Optimal speed ramping feature slowly increases speed to setpoint to avoid splashing. The load sensor detects unbalanced conditions and
automatically reduces to a safe speed.

The OHAUS Digital 45 kg Capacity Orbital Shaker is a large capacity shaker. They have a more powerful drive mechanism and larger orbits for optimal shaking of large vessels.

Operating Features:

Accu-Drive Shaking System:

The exclusive patented Shaking System delivers exceptional speed control, accuracy, and durability. The shaking system continuously monitors shaking speed and maintains setpoint, even under changing loads. When unit is set to a speed above 100 rpm, the speed accuracy is ± 1%
of set speed. When set under 100 rpm, speed accuracy is ± 1 rpm.

Microprocessor Control:

The variable speed microprocessor control provides consistent uniform shaking action. Microprocessor will display last set-point and will restart if power is interrupted.

Triple Eccentric Drive:

Permanently lubricated ball bearings and maintenance free, brushless DC motor provide reliable service and continuous duty operation.
LED Display:

Touchpad controls with easy-to-read, independent LED displays for speed and time allow operator to view both settings at once. Provides repeatable and accurate results every time and is easily visible across lab benches. Timer will display elapsed time or, when programmed to user defined limit,
will shut off unit when time reaches zero. Display will show last used settings, even after power has been turned off.

RS232 Interface:

Provides two-way communication for data logging and unit control.

Speed Calibration Mode: Allows user to automatically recalibrate speed display.

Safety Features:

Load Sensor: A built-in load sensor detects unbalanced conditions and automatically reduces rpm to a safe speed to protect samples.

Overload Protection: Audible and visual signals will activate when system detects an obstruction or overload of the tray.

Speed Ramping Feature: Slowly increases speed to desired set-point to avoid splashing.

Audible Alarm: In timed mode, alarm will sound when the time reaches zero. Alarm has optional mute function which can be set from the Touchpad control.

Spill-Resistant Design:

Channels fluids away from internal components.

Operating Conditions:

Units can be run in cold rooms, incubators, and CO2 environments from -10 to 60°C (14 to 140°F), maximum 80% relative humidity, non-condensing.


Cell cultures, solubility studies, and extraction procedures.

Ordering Information:

Units include a detachable, 3-wire cord and plug. Units are also supplied with a 24 × 24″ (61 × 61 cm) non-skid rubber mat.
