Ohaus SHHD6825DG Digital Heavy Duty Orbital Shaker

The highest-capacity model with a general-purpose orbit

The Ohaus SHHD6825DG is a digital orbital shaker in the Heavy Duty family, built for labs that need the widest weight capacity in the range while keeping a general-purpose 25 mm orbit.

At 68 kg maximum capacity, it is the largest-capacity model in the Heavy Duty line, spanning the full 16-68 kg range documented across the family.

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 68 kg at 125 rpm, scaling down to 18 kg at 300 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 SHHD6825DG ships with a built-in tray (610 x 910 mm), the largest in the family, and a non-slip rubber mat, ready to accept flask clamps, test tube racks, and the largest platforms from the shared Ohaus accessory ecosystem.

Ideal Applications

The Ohaus SHHD6825DG suits the following applications.

• The highest-volume bulk or high-throughput flask shaking
• Large-scale extractions and solubility studies
• Bacteria and yeast culture work at maximum volumes
• Staining, destaining, and blotting techniques at scale
• Labs needing RS232 connectivity or user calibration

Choose the SHHD6825DG when:

• You need the widest weight capacity in the Heavy Duty range, up to 68 kg
• A general-purpose 25 mm orbit suits your flask or vessel size
• You need accurate, repeatable speed control
• Load sensing and overload protection matter for your samples
• You want RS232 connectivity or user speed calibration

Ohaus Value Proposition

The SHHD6825DG combines the widest capacity in the Heavy Duty range with the Accu-Drive system, load sensing, and RS232 connectivity, for high-volume orbital shaking without moving to a large 51 mm orbit.

Ohaus backs the Heavy Duty range with a wide accessory ecosystem and global service network.
