Zeiss N-Achroplan 20x microscope objective, 0.45 NA, infinity-corrected, M27 thread for advanced optical microscopy.
The Zeiss N-Achroplan 20x M27 microscope objective (Part No. 420950-9900) is an achromatic objective lens designed for infinity-corrected optical microscopy systems. Featuring a 20x magnification and a numerical aperture (NA) of 0.45, this objective provides high-resolution imaging with excellent contrast essential for detailed cell imaging and biological sample analysis. It is optimized with a ∞/0.17 correction collar to minimize spherical aberrations and is mounted with an M27 thread diameter, compatible with a variety of Zeiss microscope turret systems.
This objective is widely used in biotechnology research, including molecular diagnostics, synthetic biology, and live-cell imaging, where precise optical performance is critical. Its achromatic lens design reduces chromatic aberrations, making it suitable for fluorescence analysis and brightfield microscopy in biomedical engineering and biomanufacturing workflows.
Key features include:
This objective lens supports advanced microscopy applications that require sharp, high-contrast images, making it an essential optical component in molecular biology and biotechnology laboratories focusing on gene editing and synthetic biology 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.
