Portable Endotoxin testing system Endosafe PTS model 535-91311 for rapid detection in biotech and clinical diagnostics
The Portable Endosafe PTS Endotoxin Testing System, model 535-91311 by Wako Pure Chemical Industries, is a compact and field-deployable endotoxin detection instrument widely used in biotechnology and clinical diagnostics for rapid and precise endotoxin assays. This system employs Limulus Amebocyte Lysate (LAL) assay principles to quantify endotoxin contamination in pharmaceutical products, bioprocessing workflows, and molecular diagnostic sample preparations.
This unit is a used system sold as-is, and its performance or functions may not fully match those of a new device. Verification of operational status is recommended prior to critical applications. It remains a valuable tool for biotechnology labs, clinical research facilities, and biomanufacturing pipelines where portable endotoxin monitoring is essential.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
