The HORIBA B-712 LAQUA twin Compact pH Meter is a precision instrument designed for accurate pH measurement ranging from 2 to 12 pH with a resolution of 0.1/0.01 pH and measurement accuracy of ±0.1 pH. This compact device weighs approximately 50 grams (excluding power sources) and features a highly durable ABS resin enclosure with a waterproof rating equivalent to IP67, suitable for laboratory environments requiring robust and portable pH monitoring solutions.
Key features include:
This pH meter is widely utilized in biomedical engineering, molecular biology research, and clinical diagnostics for precise pH quantification essential in gene editing, bioprocessing, and synthetic biology research. Note that this unit is used and sold as-is; performance may vary from a new product. It remains a reliable tool for labs focusing on molecular cloning workflows and biopharmaceutical production pipelines requiring precise pH control.
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.
