Product description

Digital Ohaus lab rocker offers 1-50 rpm adjustable speed, 1°-15° tilt for precise mixing in biotech workflows.

The Ohaus Lab Rocker SHRK04DG is a benchtop laboratory rocker designed for precise, low-speed mixing applications critical in biotechnology and molecular diagnostics. Featuring a digital display, it delivers an adjustable seesaw rocking motion ranging from 1 to 50 rpm with ±1 rpm speed accuracy and a tilt angle adjustable between 1° and 15° with ±1° angle accuracy. This rocker supports complex workflows such as blood sample mixing, blotting techniques, and nucleic acid hybridizations, making it essential in gene editing and synthetic biology research environments.

Key technical specifications include:

  • Speed Range: 1–50 rpm
  • Tilt Angle: 1° to 15° for gentle agitation, suitable for live-cell imaging preparations
  • Maximum Load Capacity: 4.5 kg, accommodating various sample containers and plates
  • Timer: Programmable from 1 second up to 160 hours for long-term bioprocessing protocols
  • Environmental Tolerance: Operates efficiently from -10°C to 60°C (14°F to 140°F) at 80% relative humidity, non-condensing, compatible with incubators and biosafety hoods
  • Platform Size: 13×10 inches with a rubber mat to secure vessels during rocking
  • Dimensions and Weight: Compact footprint of 11×17×6 inches and weighing 8 lbs for easy integration into lab setups
  • Electrical Requirements: 100-240 V, 50/60 Hz, 0.1A power supply ensuring worldwide compatibility

This low-profile rocker is widely adopted in synthetic biology research for its ability to deliver gentle, consistent mixing necessary in delicate molecular cloning workflows and hybridization experiments. Its robust design and precise control make it critical in biopharmaceutical production pipelines, especially in fluorescence analysis and live-cell assay preparations.

Included with the unit are a rubber mat platform, 120V power cord, user manual, and a 30-day warranty, ensuring reliable operation and support for clinical diagnostics and bioprocessing labs. The Ohaus Lab Rocker SHRK04DG combines dependable mechanical performance with digital precision, streamlined for applications across neuroscience, biotechnology, and biomedical engineering research domains.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
