Product description

Advanced Lasair II 510a air quality monitor particle counter with calibrated sampler for cleanroom and bioprocessing contamination analysis.

The Particle Measuring Systems Lasair II 510a is a precise portable particle counter and air quality monitor optimized for cleanroom environmental monitoring and contamination control. This instrument features:

  • Real-time airborne particle counting across multiple size channels, critical for bioprocessing and molecular diagnostics cleanroom validation
  • Proven use in biotechnology applications, including biomanufacturing contamination surveillance and molecular biology laboratory air monitoring
  • Calibration required prior to use to ensure measurement accuracy in sensitive environments such as pharmaceutical production and synthetic biology cleanrooms
  • Fully functional sampler and network connectivity verified; printer interface currently missing
  • Portable design facilitates compliance monitoring in cell culture facilities and live-cell imaging suites where air particulate control is essential
  • Includes AC power cord; excludes battery, battery door, and two feet stabilizers

This model supports contamination analysis vital for gene editing labs, molecular cloning workflows, and other critical biotechnological research environments requiring stringent air purity standards. Its role in environmental particle measurement makes it a key tool in fluorescence analysis and clinical diagnostics laboratories maintaining cleanroom certification.

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.
