Enhanced Laboratory Safety and Ease

This distillation unit features robust safety mechanisms including over-temperature cut-off, door interlocking, and leak protection, reducing operational risks in busy labs. Semi-automatic functions and programmable distillation times make the process straightforward, while integrated drainage and glassware facilitate smooth operation and cleanup.


Versatile Use Across Industries

The NACUDK 139 caters to diverse sectors such as agri-food, pharmaceuticals, and environmental labs, thanks to its wide nitrogen measurement range (0.1200 mg N) and compatibility with standard flask sizes. Its application is pivotal for routine nitrogen/protein estimation in research and quality control.


Accurate and Efficient Distillation

Delivering reliable results, the unit achieves up to 0.5% accuracy for nitrogen estimation. Capable of processing up to 12 samples per hour, its high-performance ceramic or alloy heating system ensures consistent temperatures up to 450C, supporting rapid, repeatable ammonia steam distillations.
