Handheld digital refractometer measuring 0–50% hydrogen peroxide with ±0.6% accuracy in 3 seconds.
The ATAGO PAL-39S is a handheld digital refractometer specifically designed for precise hydrogen peroxide concentration analysis, widely used in biotechnology, molecular diagnostics, and bioprocessing workflows. Featuring a measurement range of 0.0 to 50.0% hydrogen peroxide (g/100g scale), it delivers quick readings within 3 seconds with an accuracy of ±0.6% and a resolution of 0.2%.
This portable device requires only 2 to 3 drops of sample volume, making it suitable for rapid onsite testing in clinical diagnostics, pharmaceutical quality control, and biomanufacturing environments. Powered by 2 AAA batteries, the compact unit weighs just 100 g and measures 55×31×109 mm, facilitating easy handheld operation for field and laboratory use.
The PAL-39S is critical in synthetic biology and bioprocess monitoring where reliable hydrogen peroxide quantification is essential. Its durable design and fast measurement capability make it a valuable tool for researchers and professionals requiring rapid assessment of oxidizing agents with high precision.
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.
