PRECISE AND OPTIMIZED DISTILLATIONS TAILORED FOR EACH APPLICATION NOTE
Our Kjeldahl distillers offer unparalleled flexibility to customize each assay. With a library of up to 100 application notes of editable name, each program allows for the configuration of various parameters, such as steam generation intensity, reagent dosing volumes, delay time, distillation time, and sample aspiration. This customization makes it possible to adjust every step of the distillation process to the specific needs of each sample, ensuring the highest quality results. Additionally, the microprocessor incorporates specialized menus for priming, calibration, and cleaning of the reagent pumps.
TOUCHSCREEN AND RAYPANET ACCESS VIA WI-FI
The 5'' touchscreen displays the status of all relevant parameters of each assay in real time. Moreover, each stage of the process is clearly represented with animations, icons, and timers, making it easy to understand and follow the procedure. All models come equipped with Wi-Fi connectivity for accessing the RAYPAnet web platform from any device. The results of each assay can be consulted live or retrospectively directly on the platform by accessing the historical record of assays. All information can be exported in graphic format and reports can be generated in .CSV and .PDF formats for further consultation, study, and storage. It is possible to connect and control multiple units simultaneously.
3 OPTIONS WITH VARYING DEGREES OF AUTOMATION
All models are equipped with the same safety features and contain all the essential components to perform a Kjeldahl distillation. The most automated operation model includes sample aspiration, addition of H3BO3, an external titrator that automatically determines the analysis result, and titrator control software.
Operation
KJELDAHL DISTILLATION BY STEAM DISTILLATION
Using the Kjeldahl Distiller, the process begins by loading a previously digested sample and starting a specific program. The equipment then adds the selected reagents in the exact amount. After the necessary delay time, the steam generator injects water vapor into the sample, heating it rapidly. The analyte is then carried along by the steam. First, the sample will evaporate and then condense, collecting in the receiving flask. In the next step, the nitrogen content is determined through titration, and the results are exported directly to your PC.
To make more efficient use of water, the cooling system and the steam generator of the Kjeldahl Distiller are only activated during distillation. At the end of the distillation, the remaining residue in the sample tube is aspirated and removed.
The combination of the Kjeldahl Distiller DNP-2000-TS and the external titrator TITRA-RAY offers a unique, cost-effective, and highly efficient automation of the Kjeldahl method by transferring samples, performing rapid distillations, executing precise titrations, and properly recording the results.
