Used Nihon Kohden AB-651J bioelectric amplifier for adjustable EEG and EMG signal acquisition.
The Nihon Kohden AB-651J Bioelectric Amplifier is a used, rack-mounted amplifier module designed for high-sensitivity acquisition of bioelectric signals, including electromyography (EMG) and electroencephalography (EEG). It slides into a compatible Nihon Kohden main-unit slot and operates as one channel within a multichannel physiological measurement system.
This bioamplifier module is suitable for research, education, physiological testing equipment, and integration into existing Nihon Kohden systems used in neuroscience, biomedical engineering, and electrophysiology workflows. The unit is sold as-is; used equipment may not provide the same performance or functionality as when new.
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.
