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.

Funcionamiento Destilador

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.

FAQS

What connections does the equipment have?

The equipment has an inlet and an outlet for cooling water, reagents (NaOH and boric acid in the case of a DNP-2000 TS model distiller) and a distilled water inlet to generate steam. Additionaly, there's an outlet of waste solution in the models equipped with residue aspiration.

Where does the waste from samples end up?

If the model is equipped with sample aspiration, the residue will be automatically removed into a labeled tank. If sample aspiration is not available, the residue must be removed manually.

Where can I obtain the necessary reagents for the Kjeldahl distiller?

Reagents for the Kjeldahl distiller can be acquired from companies specializing in the production and distribution of laboratory chemicals. RAYPA provides only the equipment and its components, not the reagents.

What is the typical distillation duration with the Kjeldahl distiller?

Distillation time varies based on the sample type but generally falls between 4 to 6 minutes per sample.
