Product description

Heavy-duty magnetic stirrer with strong magnetic coupling, stable speed control, for up to 30L volume.

The Stuart Scientific SB301 Magnetic Stirrer is a robust benchtop magnetic stirring device designed for continuous stirring of large volume liquids (up to approximately 30 liters of water-equivalent). Engineered for chemistry, biology, and environmental laboratories, it provides reliable agitation without mechanical interference such as overhead stirrers or impellers.

Key technical features include:

  • Strong magnetic coupling to efficiently drive stir bars even under heavy load conditions
  • Stable speed control ensures consistent stirring rates essential for reproducible experimental results
  • Capable of handling volumes up to 30 L, making it suitable for bioprocessing, molecular biology, and environmental sample preparations
  • Durable construction for long-term operation in demanding laboratory environments

This magnetic stirrer is especially valuable in biotechnology applications requiring gentle yet consistent mixing, such as gene editing workflows, molecular diagnostics sample preparations, and synthetic biology experiments. Its stable agitation without mechanical agitation reduces risks of sample contamination and physical stress, critical in biomanufacturing and bioprocess development pipelines.

Widely used by researchers in biomedical engineering, cell imaging laboratories, and clinical diagnostics, the SB301 supports workflows involving large-volume buffer preparations, culture medium homogenization, and reagent blending.

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?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
