Automatic distillation system with LED display, preset steam power, for Kjeldahl nitrogen and protein analysis.
The Gerhardt Vapodest 20 is a precision automatic distillation system designed primarily for Kjeldahl nitrogen determination and protein analysis in biochemical and molecular diagnostics laboratories. This instrument integrates an LED screen for intuitive control and monitoring, enabling automated addition of reagents such as NaOH or H₂O during the distillation process.
Key technical features include:
The Vapodest 20 is essential for workflows in biotechnology and molecular biology, facilitating accurate nitrogen quantification and protein content analysis crucial for bioprocessing, molecular cloning, and biopharmaceutical production pipelines. Its automated reagent dosing and controlled steam power ensure reproducibility critical for synthetic biology research and clinical diagnostics. This system is widely adopted in laboratories focusing on cellular biochemistry, food analysis, and environmental testing, supporting efficient and precise distillation protocols in life science research disciplines.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
