The Kubota 4000 tabletop centrifuge features a microprocessor-controlled brushless motor providing precise operation with maximum speeds up to 6,000 rpm and a centrifugal force reaching 5,350×g. Designed for laboratory bioprocessing and molecular diagnostics, it accommodates up to 1,020 mL sample volume, suitable for various applications including synthetic biology and gene editing workflows. Its programmable control supports digital speed and RCF settings with 10 rpm and 10×g increments respectively, and timer ranges from 1 second to nearly 100 minutes, facilitating versatile protocol customization.
Key operational parameters include dual-stage acceleration (fast/slow) and tri-stage deceleration (fast, slow, free-run), enhancing sample integrity during spin-downs. Safety mechanisms detect door open status, imbalance, overspeed, rotor installation errors, and electrical faults in motor or sensors, ensuring reliable performance critical for clinical diagnostics and biomanufacturing environments.
The centrifuge includes the ST-722M swing rotor compatible with 15 mL conical tubes (via the 055-4780 tube rack, 32 capacity), widely adopted in cell imaging and biotechnological research. The user interface offers digital displays, multi-color status lamps, and adjustable sound notifications for process monitoring. Physical dimensions (44×56×31 cm) and weight (36 kg) provide a compact footprint suitable for benchtop deployment.
Its rated electrical specifications (AC 100 V, 8.4 A) and power consumption (550 W) support stable operation in standard laboratory settings. Previously maintained by the manufacturer, this unit is supplied as a dependable used centrifuge, ideal for research labs requiring robust and programmable centrifugation capabilities in molecular biology, biotechnology, and biomedical engineering applications.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
