Product description

High numerical aperture 40x oil immersion phase contrast objective with RMS 20mm thread for advanced microscopy.

The Zeiss Planapo 40x Oil Ph3 160/- microscope objective (Part No. 461747-9903) is a high-quality, oil immersion phase contrast lens designed for advanced light microscopy applications. This objective features a numerical aperture (NA) of 1.0, providing enhanced resolution and brightness essential for detailed cellular and subcellular imaging in biotechnology and molecular diagnostics.

Key technical specifications include:

  • Magnification: 40x
  • Phase contrast type: Phase 3 (Ph3) ring for optimized contrast of transparent specimens
  • Immersion medium: Oil, improving numerical aperture and image clarity
  • Mechanical tube length: 160 mm
  • RMS thread diameter: 20 mm, compatible with standard microscope nosepieces
  • Iris diaphragm collar: Adjustable, allowing fine control of phase contrast illumination (note: slight stiffness reported)
  • Functionality: Spring mechanism operates correctly, verified to produce sharp, high-quality images

This objective is widely used in biomedical engineering and biotechnology research fields, particularly in live-cell imaging, fluorescence analysis, and neuroimaging applications. It is critical for workflows requiring precise phase contrast visualization such as molecular cloning, cellular morphology studies, and synthetic biology research. The Planapo series by Zeiss is known for superior optical correction and flatness of field, making it indispensable in biopharmaceutical production pipelines that demand accurate and reproducible microscopy data.

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.
