Ohaus SHHD2325DG Digital Heavy Duty Orbital Shaker

A digital heavy duty orbital shaker for mid-capacity loads

The Ohaus SHHD2325DG is a digital orbital shaker in the Heavy Duty family, built for labs that need accurate, repeatable speed control on larger sample loads.

It shares its mechanical platform, orbit, and accessory ecosystem with the analog SHHD2325AL, adding digital control, an RS232 interface, and safety monitoring on top.

Accu-Drive shaking system and triple eccentric drive

The Accu-Drive shaking system delivers speed control, accuracy, and durability, paired with a brushless DC motor and triple eccentric drive that keeps the tray flat through the entire speed range.

Speed accuracy is within 1% of the set speed above 100 rpm, and within 1 rpm below 100 rpm.

Load sensing and overload protection

An integrated load sensor detects unbalanced or excess-load conditions and automatically reduces speed to protect the sample, backed by overload protection and an audible alarm.

• Weight capacity of 23 kg at 125 rpm, scaling down to 4.5 kg at 500 rpm
• Timer adjustable from 1 second to 160 hours
• Working environment of -10°C to 60°C, 80% RH, non-condensing

RS232 interface and user calibration

The built-in RS232 interface and user speed calibration support integration into documented, quality-controlled workflows where reproducibility needs to be demonstrated.

Included tray and the wider accessory ecosystem

The SHHD2325DG ships with a built-in tray (457 x 610 mm) and a non-slip rubber mat, ready to accept flask clamps, test tube racks, and platforms from the shared Ohaus accessory ecosystem of 70-plus options.

Ideal Applications

The Ohaus SHHD2325DG suits the following applications.

• Cell culture in larger flasks and general suspensions
• Extractions and solubility studies requiring documented speed accuracy
• Bacteria and yeast culture work at moderate volumes
• Staining, destaining, and blotting techniques
• Labs needing RS232 connectivity or user calibration

Choose the SHHD2325DG when:

• You need accurate, repeatable speed control
• Your capacity needs fall in the 23 kg range
• You want RS232 connectivity or user speed calibration
• Load sensing and overload protection matter for your samples
• A 25 mm orbit suits your flask or vessel size

Ohaus Value Proposition
