Bio-Rad 3550 microplate reader supports multiple wavelengths for precise biochemical assays.
The Bio-Rad 3550 Microplate Reader is designed for multi-wavelength absorbance measurements, essential for biotechnology applications such as molecular diagnostics, enzyme assays, and cell-based assays. This reader supports detection at key wavelengths including 405 nm, 415 nm, 450 nm, 490 nm, 550 nm, and 595 nm, allowing for versatile biochemical and immunological analyses. The instrument is widely utilized in bioprocessing and gene editing workflows, offering precision absorbance readings critical for biopharmaceutical production pipelines. Being a used unit, it is sold "as-is" without assurances of original performance, thus verification of functionality is recommended before deployment in sensitive synthetic biology or molecular cloning projects. This microplate reader is suitable for laboratories conducting fluorescence analysis and cell imaging-based assays, and it integrates well in clinical diagnostic and research environments targeting biomanufacturing and molecular biology research.
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.
