Fixed-angle rotor for Beckman Avanti centrifuges, 8×50 mL capacity, 20,000 rpm, 48,400 × g for cell harvesting and bioprocessing.
The Beckman Coulter Avanti JA-20 Fixed Angle Rotor is a precision-engineered centrifuge rotor designed for compatibility with Avanti JXN-26, J-26S, J-E, and JXN-30 centrifuge models. This fixed-angle rotor supports eight 50 mL tubes and operates at a maximum speed of 20,000 rpm, generating centrifugal forces up to 48,400 × g. It features a k-factor of 769, optimizing sedimentation efficiency for applications including harvesting bacterial pellets, processing tissue homogenates, and separating cellular particulates critical in molecular diagnostics and bioprocessing workflows.
Key technical specifications:
The rotor is rigorously tested for balance and stability under load to ensure consistent, vibration-free performance, essential for maintaining sample integrity in biotechnology, cell imaging, and biomanufacturing research environments. Constructed with durable materials, it supports reproducible results in synthetic biology studies and molecular cloning workflows requiring reliable pelleting efficiency.
This rotor is widely adopted in clinical diagnostics and biomedical engineering laboratories where high-speed pelleting of medium-volume samples is common. Its compact design allows integration within benchtop centrifuge systems while delivering centrifugal forces suitable for bioprocessing protocols that require stringent separation of cellular components.
Technical buyers and laboratory managers will benefit from the comprehensive testing, warranty coverage, and after-sales support provided. The rotor’s proven reliability and compatibility with popular Avanti centrifuges make it a critical component in advanced centrifugation setups used in gene editing research and other modern biotechnological 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.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
