Product Overview
The VELP Scientifica NDA 702 is a fully automatic nitrogen and protein analyser based on the Dumas combustion method. The NDA 702 provides rapid determination of total nitrogen and protein content in solid and liquid samples, delivering results in as little as three minutes without the need for chemical reagents or hazardous waste disposal associated with the traditional Kjeldahl method.
The NDA 702 is used for quality control and research in the food and beverage, animal feed, agriculture, pharmaceutical and environmental industries. It complies with AOAC, ISO, AACC and other international standards for nitrogen/protein analysis by combustion. Its fully automated operation, including sample weighing verification, combustion, gas separation and detection, makes it ideal for high-throughput laboratories seeking faster results and greener chemistry.
