Product description

Upright microscope with water immersion optics, IR-DIC, and vibration-free frame for advanced physiological imaging.

Olympus BX51WI is a specialised upright microscope engineered for advanced physiological experiments, including patch clamping and intravital microscopy. Its fixed-stage design and vibration-free frame provide exceptional stability, ensuring precise imaging during sensitive procedures.

Key features:

  • Water immersion optics: Optimised for electrophysiological applications, enhancing image clarity in live-cell studies.
  • Infrared-Differential Interference Contrast (IR-DIC): Facilitates deep tissue imaging with minimal phototoxicity, crucial for observing thick biological samples.
  • Long working distance objectives: Provide ample space for microelectrodes, essential in electrophysiology experiments.
  • Front operation system: Minimises vibration and noise, preventing interference during delicate procedures.
  • Modular design: Allows customisation with various accessories to meet diverse research needs.

Applications:

  • Neuroscience: Ideal for studying neural circuits and brain slice preparations.
  • Electrophysiology: Supports patch-clamp recordings and other electrical measurements in live cells.
  • Live-cell imaging: Enables observation of dynamic cellular processes in real-time.
  • Biotechnology: Essential for molecular cloning workflows and synthetic biology research.

Commonly used in:

  • University laboratories: Facilitates advanced research and teaching in life sciences.
  • Biomedical research centres: Supports cutting-edge studies in cellular and molecular biology.
  • Clinical environments: Assists in diagnostic procedures and translational research.

Introduced in the early 2000s, the BX51WI remains a valuable tool in contemporary research settings, reflecting Olympus's commitment to innovation in scientific instrumentation.

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.
