Refillable double-junction combination pH electrode for fluoride-rich samples, BNC connector, glass body, hydrofluoric acid resistant.
The Hanna HI 1143B is a highly specialized refillable combination pH electrode featuring a double-junction design and a durable glass body, engineered specifically for accurate pH measurements in challenging chemical environments containing hydrofluoric acid (up to 2 g/L at pH 2, temperature below 60°C).
Key technical features include:
This electrode is essential for researchers engaged in biotechnology applications involving corrosive chemical processes, molecular diagnostics, or biomanufacturing workflows requiring precise pH control in fluoride-containing solutions. Its refillable design enhances longevity and reduces operational costs in bioprocessing environments.
Widely adopted in environments where fluoride ion interference must be minimized, the Hanna HI 1143B stands as a critical tool in synthetic biology research and clinical diagnostics laboratories focused on aggressive sample analysis.
For ordering or inquiries about alternative electrode types suited for diverse analytical needs, contact the supplier directly.
This electrode supports accurate and stable pH measurement imperative for maintaining optimal conditions in biomedical engineering and industrial biotechnology processes involving fluoride chemistry.
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.
