Nikon Plan 20x/0.4C/DL objective lens for microscope imaging with high numerical aperture, used condition.
This Nikon Plan 20x/0.4C/DL microscope objective lens is designed for high-quality optical imaging in microscopy applications. Featuring a numerical aperture of 0.4, it provides a good balance of resolution and depth of field, suitable for brightfield and contrast-enhanced imaging. As a Plan objective, it offers a flat-field correction across the image, ideal for precise cellular imaging and biotechnology workflows. This lens is compatible with Nikon microscope systems and is widely used in biomedical engineering, molecular diagnostics, and live-cell imaging to enable critical observation in gene editing and synthetic biology research. Please note this unit is used and sold as-is, which means original new performance and functionality might be partially compromised. Buyers should verify compatibility and condition to ensure it meets the specific requirements of biotechnological research and clinical diagnostic workflows.
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.
