Widely adopted in synthetic biology research and biomanufacturing, the InPro 3100/120 PT100 supports accurate pH measurement essential for gene editing workflows and essential upstream bioprocess controls. Its analog output enables straightforward integration with standard process control systems in biotechnology facilities.
In summary, the Mettler Toledo InPro 3100/120 PT100 is a state-of-the-art bioprocess pH sensor optimized for rigorous use in biotechnology, pharmaceutical research, and clinical diagnostics applications requiring precise, dependable pH measurement under stringent sterilization conditions.
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.
