Product description

Advanced trinocular microscope with 20 mm field, 5W LED, phase contrast, oil immersion, and digital imaging readiness.

The Accu-Scope EXC-250 is a robust trinocular microscope designed for clinical, educational, and research laboratories, delivering *reliable high-contrast imaging* with advanced Infinity Plan achromat optics. Featuring a 20 mm wide field of view, this microscope supports brightfield, phase contrast, darkfield, polarization, and 100x oil immersion applications, essential for biotechnology workflows including molecular diagnostics and cell imaging.

Key technical features include:

  • Trinocular viewing head, 30° inclined and 360° rotatable, optimized for ergonomic comfort and prolonged use in neuroimaging and biomedical engineering.
  • Infinity Plan achromat objectives with magnifications 4x, 10x, 40xR, and 100xR oil immersion, providing flat, crisp images critical in synthetic biology and biomanufacturing research.
  • High working distance (HWF) 10x/20 mm paired eyepieces with pointer and eyeguards for precision specimen analysis.
  • Reversed quadruple nosepiece and mechanical stage (140 × 132 mm) facilitating seamless specimen transitions in live-cell imaging and fluorescence analysis.
  • Integrated Abbe condenser with N.A. 1.25 and iris diaphragm, delivering superior illumination control for diverse microscopy techniques.
  • Coaxial coarse and fine focus controls designed to reduce operator fatigue during extended sessions of gene editing and bioprocessing analysis.
  • Variable intensity 5-watt LED illumination offering over 25,000 hours lifespan, ensuring consistent brightfield light source efficiency.
  • Digital imaging ready with a 50:50 light split enabling attachment of Excelis™ cameras or USB, HD, and Wi-Fi imaging devices, supporting documentation and collaborative research in molecular cloning and clinical diagnostics.
  • Additional convenience features include a durable cast-alloy frame, compact footprint, integrated carry handle, cord wrap, and built-in USB power port for mobile device charging.

Widely adopted in molecular biology, biotechnology, and clinical research laboratories, the EXC-250 microscope is critical in biopharmaceutical production pipelines and essential for high-precision microscopy applications requiring scalable system upgrades.

This microscope’s modular design supports future upgrades, expanding its utility across various research domains such as synthetic biology, live-cell fluorescence, and neuroimaging applications—making it a versatile solution for evolving laboratory demands.

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?

Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
