Thermo-reactor with 25-vial capacity, programmable temperature control (30–170°C), designed for COD and timed digestion processes.
The Hanna HI 839800 COD Reactor is a precision thermo-reactor optimized for Chemical Oxygen Demand (COD) analysis and other digestion-based laboratory workflows essential in environmental chemistry and biotechnology bioprocessing. It accommodates up to 25 test vials (Ø 16 mm x 100 mm) simultaneously, enabling efficient sample throughput in molecular diagnostics and biomedical engineering applications requiring controlled thermal digestion.
This thermo-reactor is a critical instrument widely adopted in synthetic biology research and biopharmaceutical production pipelines, assisting in sample preparation steps such as molecular cloning workflows and synthetic nucleic acid digestion. Its precise temperature control and multi-vial capacity make it indispensable for researchers and laboratories focusing on clinical diagnostics and environmental toxicology studies. The device’s features facilitate reliable chemical digestion processes aligned with regulatory and research standards.
The Hanna HI 839800 is a key tool for labs requiring a dependable, programmable reactor for simultaneous digestion in biotechnology, environmental science, and analytical chemistry domains.
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.
