Product description

Compact AC halogen light source with solid state dimmer, 120V input, 0.75-inch connector, for precise lab illumination control.

The Fostec Model 20500.2 is a reliable AC halogen light source designed for scientific and industrial laboratory applications, including biotechnological research and molecular diagnostics requiring controlled illumination. It features a solid state dimmer enabling variable light intensity, which is critical in live-cell imaging and fluorescence analysis workflows.

Key technical details include:

  • Input voltage: 120V suitable for standard lab power supplies
  • Connector diameter: 0.75 inches (1.905 cm), compatible with multiple optical systems
  • Compact and rugged construction facilitating benchtop setup in biotechnology labs
  • Operational fan for thermal management, ensuring stable light output
  • Condition: Very good with minor cosmetic wear; missing a light bulb connecting component, which may require replacement for full functionality

This halogen light source is essential for applications demanding consistent and adjustable illumination intensity, such as bioprocessing instrumentation, synthetic biology experiments, and quantitative fluorescence analysis. Its compact form factor makes it widely adaptable in various experimental setups in biotechnology and clinical diagnostics laboratories. The solid state dimmer supports precise control over illumination parameters, enhancing reproducibility in optical measurements critical for gene editing and molecular cloning workflows.

The product's harmonized code 85414010 classifies it as a photosensitive semiconductor device, underlining its role as an illumination component in sophisticated laboratory instruments.

This Fostec halogen source is particularly suited for researchers focusing on live-cell imaging, biomedical engineering, and biomanufacturing processes requiring durable and finely tunable laboratory light sources.

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.
