High-performance AB Sciex API 4000 mass spectrometer with triple quadrupole for sensitive quantitative analysis in complex matrices.
The AB Sciex API 4000 is a triple quadrupole mass spectrometer engineered for sensitive and selective quantitative mass spectrometry. Its advanced ion optics system enables rapid polarity switching and multiple reaction monitoring (MRM), essential for precise and reproducible data acquisition. This instrument supports a range of sample introduction systems, enhancing adaptability for diverse laboratory workflows, including pharmacokinetics, clinical diagnostics, and environmental analysis. Widely adopted in biotechnology and molecular diagnostics, it is crucial for applications in bioprocessing workflows, drug metabolism studies, and synthetic biology research. The API 4000’s robust design ensures durability and reliability, making it an optimal choice for laboratories specializing in mass spectrometry-based quantitation and biomedical research.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
