Battery-powered bench-top electrical isolator with selectable voltage/current output modes and stimulation control.
The Nihon Kohden SS-401J is a compact, battery-powered bench-top electrical isolator designed for electrically separated signal application and evaluation. It provides selectable voltage and current output modes for laboratory equipment, medical-device testing, and experimental setups requiring electrical isolation.
The battery-powered design supports electrical isolation between medical instruments, laboratory equipment, and test circuits. This used signal isolator may be suitable for research laboratories, inspection environments, biomedical engineering, electrical safety evaluation, and experimental signal stimulation applications. It is supplied without accessories and is offered in as-is condition.
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.
