Product description

High-performance Zeiss 40x/0.95 Korr microscope objective with apochromatic correction for fluorescence and brightfield imaging.

The Zeiss Plan-Apochromat 40x/0.95 Korr Microscope Objective (Part No. 420660-9970) is a high-precision, dry objective lens optimized for advanced microscopy applications in biotechnology, molecular diagnostics, and cell imaging. This objective features an apochromatic optical system with Infinity Color Corrected System (ICS), ensuring superior color fidelity and aberration correction critical for fluorescence analysis and brightfield microscopy.

Key technical specifications include:

  • Magnification: 40x
  • Numerical Aperture (NA): 0.95 for enhanced resolution and light-gathering capability
  • Free Working Distance: 0.25 mm, suitable for close specimen access
  • Coverglass Thickness: Compatible with 0.13 - 0.21 mm, ideal for standard slides used in biomedical engineering and synthetic biology workflows
  • Thread Type: M27x0.75 for secure mounting on compatible microscopes
  • Immersion Type: Dry (no immersion medium required), simplifying sample preparation
  • Field of View: 25 mm diameter, providing sufficient sample overview for live-cell imaging and fluorescence spectroscopy
  • Parfocal Length: 45.06 mm ensures focus retention when switching objectives
  • Iris: None, optimized for consistent light transmission
  • Applications: Excellent performance in fluorescence, brightfield, and DIC microscopy; not suitable for phase contrast, darkfield, or reflected light methods

This objective has been verified on the Zeiss Observer 7 microscope to ensure optical precision and mechanical integrity. It is thoroughly inspected, cleaned, and calibrated by trained technicians. The robust design is critical for high-resolution imaging tasks in bioprocessing, gene editing research, and clinical diagnostics, contributing to reliable data acquisition in molecular biology and biomanufacturing pipelines.

Ideal for researchers requiring reliable, apochromatically corrected optics, this Zeiss objective supports high-quality fluorescence and brightfield microscopy, which are essential for detailed cellular imaging and fluorescence labeling techniques widely used in biotechnology and synthetic biology research environments.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
