pH electrode protection solution with 3M KCl for stable reference electrode performance in molecular diagnostics.
The Ohaus pH Electrode Protection Solution (3M KCl) is a high-purity electrolyte solution designed to maintain optimal hydration and stable function of pH reference electrodes. Formulated with 3 molar potassium chloride (KCl), this solution ensures consistent ionic strength critical for reliable pH measurement in clinical diagnostics, bioprocessing, and molecular biology applications. Ideal for electrode storage and maintenance, it prevents electrode degradation, extending sensor lifespan and enhancing accuracy in biotechnology research workflows such as gene editing and synthetic biology. Trusted by laboratory professionals, this solution supports high-precision applications including live-cell imaging and fluorescence analysis where stable pH measurement is essential. Manufactured by Ohaus, the product is shipped directly for rapid delivery and factory-fresh quality assurance.
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.
