Product description

Kubota 4000 benchtop centrifuge, 6000 rpm max speed, 5,350×g max RCF, 1,020mL capacity.

The Kubota 4000 benchtop centrifuge with ST-722 M swing rotor is designed for laboratory applications requiring moderate-speed centrifugation with high relative centrifugal forces up to 5,350×g. This benchtop centrifuge features a maximum rotation speed of 6,000 rpm and a maximum sample capacity of 1,020 mL, suitable for biotechnology workflows including bioprocessing and molecular diagnostic sample preparation.

Key specifications and features:

  • Maximum speed: 6,000 rpm ensures efficient sedimentation for various applications in cell imaging and molecular biology.
  • Maximum relative centrifugal force: 5,350×g delivers adequate force for pelleting cellular components, DNA, or proteins.
  • Capacity: Accommodates up to 1,020 mL allowing preparation of multiple samples simultaneously, essential in biomanufacturing and synthetic biology labs.
  • Electrical requirements: Operates on AC 100 V, 50/60 Hz with rated current of 8.4 A and power consumption of 550 W, suitable for standard laboratory power supplies.
  • Compact footprint: Dimensions of 44 × 56 × 31 cm optimize benchtop space usage in clinical diagnostics and biotechnology laboratories.
  • Durability and transport: Weighing 36 kg with a door-open height of 75 cm, appropriate for benchtop installation and routine sample processing.
  • Included accessory: Equipped with the ST-722 M swing rotor designed for smooth rotational motion, improving sample integrity during centrifugation.

This benchtop centrifuge is widely adopted in synthetic biology research, critical in molecular diagnostics and biopharmaceutical production pipelines, and valuable for routine centrifugation tasks. Despite being a used unit sold as-is, it remains a reliable tool in biotechnology labs focused on gene editing and cell biology research. Users are advised to verify operational condition due to used status.

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.
