Ohaus SHHD1619DG Digital Heavy Duty Orbital Shaker

A digital heavy duty orbital shaker built for accuracy

The Ohaus SHHD1619DG is a digital orbital shaker in the Heavy Duty family, built for labs that need accurate, repeatable speed control and documentation-friendly features.

It shares its mechanical platform, orbit, and accessory ecosystem with the analog SHHD1619AL, 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 16 kg at 75 rpm, scaling down to 2.3 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 SHHD1619DG ships with a built-in tray (279 x 330 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 SHHD1619DG suits the following applications.

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

Choose the SHHD1619DG when:

• You need accurate, repeatable speed control
• Your capacity needs fall in the 16 kg range
• You want RS232 connectivity or user speed calibration
• Load sensing and overload protection matter for your samples
• A 19 mm orbit suits your flask or vessel size

Ohaus Value Proposition
