Product description

Nikon ELWD Ph3DL .55 160/0-2.5 phase contrast microscope objective lens with long working distance.

The Nikon ELWD Ph3DL .55 160/0-2.5 Phase Contrast Objective Lens is designed for advanced microscopy requiring long working distance and phase contrast imaging capabilities. This objective lens features:

  • Extra Long Working Distance (ELWD) suitable for samples requiring more space between the lens and specimen, ideal for live-cell imaging and biotechnology applications.
  • Numerical Aperture (NA) of 0.55, balancing resolution and depth of field, enabling detailed phase contrast imaging.
  • Standard 160 mm tube length compatibility, widely used in many Nikon microscope systems.
  • Phase contrast (Ph3DL) optics, essential for visualizing transparent biological samples without staining, making it valuable in molecular diagnostics and synthetic biology workflows.
  • Magnification factor 0-2.5, appropriate for precise cellular and microbiological observations.

This objective lens is used and sold as-is, which may affect its performance and functionality compared to new Nikon lenses. It is commonly implemented in biomedical engineering, cell imaging, and bioprocessing research where long working distance optics enable non-invasive analysis of live samples.

As a core component in phase contrast microscopy setups, this Nikon ELWD objective facilitates clear visualization of unstained cells and microorganisms, making it essential for researchers in biotechnology, molecular cloning workflows, and clinical diagnostics requiring precise optical performance with extended working space.

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.
