Product description

Trinocular microscope with Infinity Plan optics, LED illumination, ergonomic design, digital imaging ready for biotech labs.

The Accu-Scope EXC-250 is a high-performance trinocular laboratory microscope engineered for optical clarity and durability in clinical diagnostics, biotechnology, and biomedical research. Featuring an advanced Infinity Plan achromat optical system paired with a super-bright 5-watt LED illuminator optimized for brightfield, phase contrast, and 100x oil immersion, it delivers sharp, high-contrast images with a best-in-class 20 mm field of view.

Key technical specifications include:

  • Trinocular head: 30° inclined, 360° rotatable with a 50:50 light split for supporting Excelis™ cameras and USB, HD, or Wi-Fi digital imaging systems critical for documentation and molecular diagnostics workflows.
  • Objectives: Four Infinity Plan achromat objectives with magnifications of 4x, 10x, 40xR, and 100xR oil immersion, enabling detailed cellular and molecular level analysis.
  • Eyepieces: Paired 10x/20 mm high wide field with an eyeguard and pointer to enhance user precision during gene editing and synthetic biology experiments.
  • Mechanical stage: 140 × 132 mm size for stable specimen manipulation, essential in bioprocessing sample preparations.
  • Illumination: Long-life 5-watt variable LED with 25,000+ hours lifetime reduces maintenance costs and provides consistent illumination across diverse imaging applications.
  • Ergonomics: Features low-positioned coaxial coarse and fine focus controls, and low-profile stage controls designed to alleviate user fatigue during extended research sessions.
  • Expandability: Supports phase contrast, darkfield, and polarization upgrades without compromising optical integrity, widely adopted in synthetic biology research and fluorescence analysis.

The EXC-250’s robust cast-alloy frame, compact footprint, and practical additions such as an integrated carry handle, cord wrap, and built-in USB power port, make it a reliable tool for daily use in both laboratory and educational settings. This microscope is essential for biopharmaceutical production pipelines and live-cell imaging applications due to its precision and versatility.

This model represents an advanced successor to the 3000-LED series, delivering enhanced optical performance and ease of integration with modern digital imaging technologies that are critical for biotechnology and clinical diagnostics laboratories.

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.
