Product description

Motorized Zeiss condenser 0.9 NA, achromatic-aplanatic with DIC and darkfield rings for Axioplan/Axioskop microscopes.

The Zeiss 1159-531 is a motorized achromatic-aplanatic microscope condenser with a numerical aperture (NA) of 0.9, designed for advanced biotechnology and biomedical imaging applications. This condenser is optimized for use with motorized Axioplan and Axioskop microscope models, supporting high-resolution imaging essential in molecular diagnostics, synthetic biology research, and other cell imaging workflows.

Key features include:

  • Achromatic-aplanatic optics for minimized chromatic and spherical aberrations, crucial for precise fluorescence and live-cell imaging
  • Built-in Differential Interference Contrast (DIC) capability with empty DIC positions, allowing enhanced contrast imaging in unstained biological samples
  • Included 3-phase and darkfield rings for specialized illumination techniques used in neuroscience and bioprocessing research
  • Motorized control enhances automation and reproducibility in complex microscopy workflows, critical for biomanufacturing process monitoring and gene editing experiments

This condenser supports versatile illumination methods, making it widely adopted in molecular cloning workflows and clinical diagnostics. The integration into motorized systems facilitates seamless transition between imaging modalities, improving throughput and accuracy essential in high-demand laboratory 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.
