Product description

High-sensitivity alpha spectrometer with digital signal processing and modular design for precise radiation measurement.

The Alpha I is a state-of-the-art alpha spectrometer designed for precise measurement of alpha particle emissions, essential in fields such as nuclear physics, radiation safety, and environmental monitoring. This instrument offers unparalleled sensitivity and accuracy, making it indispensable for laboratories requiring detailed alpha radiation analysis.

Key features include:

  • Integrated digital signal processing: Enhances stability and resolution, crucial for long-duration measurements of low-level samples.
  • Modular design: Available in configurations ranging from single-channel to multi-channel systems, accommodating diverse laboratory needs.
  • User-friendly interface: Simplifies operation and data interpretation, facilitating efficient workflow.
  • Compact and robust construction: Ensures durability and suitability for both stationary and mobile laboratory setups.

The Alpha I is widely utilised in university research laboratories, nuclear facilities, and environmental monitoring agencies. Its applications span from radiation safety assessments to geological sample analysis, providing critical data for scientific research and public health.

First introduced in the early 2000s, the Alpha I remains a relevant and trusted tool in the scientific community, continually supporting advancements in radiation detection and analysis.

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.
