Semi-Automatic Distillation Unit
The UDK Series Distillers are designed to meet the most challenging demands and requirements for diverse applications, according to international standards: Kjeldahl nitrogen TKN, proteins, ammoniacal nitrogen, nitric nitrogen (Devarda), phenols, TVBN and volatile acids, cyanides, and alcohol content.
Five different UDK models are available with different automation levels to match any laboratory requirement of automation and throughput. The UDK Distillers address any laboratory requirements from few samples per day to unattended operations with different level of automation for NaOH, H2O and Boric Acid addition. The UDK distillers guarantee reproducible results with a RSD ≤ 1% and are able to recover more than 99.5% of Nitrogen. With a Limit of Detection of 0.015 mg N the UDK are the perfect solution even for challenging low nitrogen applications.
