Product catalog summary
Main Fields of Application
The DNP Series Kjeldahl distillers are utilized in diverse industries including food, animal feed, beverages, agriculture, environmental analysis, pharmaceuticals, and cosmetics. They are designed to analyze protein, non-protein nitrogen, and compounds like ammonia, nitrate, and formaldehyde, adhering to standards from organizations such as AOAC, ISO, and EPA.
Features and Benefits
The distillers offer flexibility with models ranging from semi-automatic to automatic, ensuring user safety with features like automatic distillation interruption and adjustable cooling water input. They support up to 100 programs with customizable settings for various sample types. Maintenance is simplified with predefined programs for cleaning and calibration.
Technological Advancements
Equipped with a touchscreen microprocessor, the distillers provide an intuitive interface supporting multiple languages and audiovisual safety alarms. The RAYPAnet online platform enables Wi-Fi connectivity for assay information export and report generation.
Complete Kjeldahl Solution
The solution includes a digester, fumes neutralization system, distiller, and titrator, designed to optimize productivity and user-friendliness by automating the Kjeldahl method, thus enhancing workflow efficiency and assay quality.
Operation and Safety
Operation involves loading the sample, selecting a program, and performing steam distillation. Safety features include open door sensors, overtemperature thermostats, and pressure switches. The system conserves resources by activating water systems only during distillation.
Technical Specifications
The DNP Series includes models like DNP-1500 TS and DNP-2000 TS, featuring automatic sample residue aspiration and external titrator compatibility. They comply with international standards and provide accurate, reproducible results with high nitrogen recovery rates. Key specifications include a width of Ø mm 35 - 22, an adapter for Büchi® tubes, and a removable tray for collecting drops. The system includes pumps and tanks for NaOH, H3BO3, and H2O, with respective volumes of 10L, 5L, and 10L.
Safety and Sensors
The distillers are equipped with audiovisual warning alarms, open door sensors, sample tube detection, a safety thermostat, and a safety pressure switch to ensure user safety and operational efficiency.
External Titrator Accessory
Optional features with the external titrator include distilled sample titration, USB and Ethernet ports for PC connection, data logging, and user management capabilities. The titrator software allows control over the titration unit, real-time data display, and data export functionalities.
Accessories and Components
The distillers come with complete batch handling items such as polyethylene tanks for NaOH, H2O, and sample residues, an anti-drip tray, and a distillation glass tube. Additional accessories include a kit for automatic titration and reinforced distillation tubes for specific analyses.
Performance and Installation
Performance data highlights a resolution of pH; mV 0.001; 0.1 and reproducibility of pH ±0.001. Installation requirements include dimensions of 220 x 400 x 360 mm, a weight of 4 kg, and power specifications of 80 W at 230 V.
Regulations and Compliance
The Kjeldahl distillers comply with international standards such as EN-61010-1, EN-61010-2-081, UNE-EN-ISO 9001:2015, EN-61326, 2014/35/UE, and 2014/30/UE. They are designed to meet various international standards like AOAC, ISO, EPA, and DIN.

Kjeldahl distillers OPERATION Once the sample is digested and ready for distillation, load it into the distiller and choose the required program. The equipment adds the selected reagents quantity and the analyte is separated by steam distillation. At first it is evaporated and then it condenses falling into the receiver flask. In the next step nitrogen content is accurately determined through titration and results are exported into your PC. To save water, the steam generator and the water refrigeration circuit are only activated during distillation. Once the distillation is completed, the residue...
