Wet Digester B-440
The Wet Digester B-440 allows an ecological incineration of different types of samples. A wide temperature range (up to 600 °C) is available. Programmable incineration ramps allow for reproducible procedures.

Scrubber K-415
The Scrubber with its four cleaning steps provides maximum safety. It protects the user and the environment not only by neutralizing the poisonous fumes and reaction gases but also by minimizing the use of cooling water.

KjelFlex K-360
Perform Kjeldahl nitrogen or protein determination and additional steam distillation in the most flexible way. The modular setup allows to adapt the KjelFlex K-360 at any time including a wide selection of titrators to guarantee smooth and easy operation.

Consumables for Sample Preparation
The nitrogen free weighing boats are perfect to easily weigh in powder, sticky, or other difficult samples. The broad range of sample tubes, makes it easy to find the right solution for every application.

Consumables for Distillation & Titration
The chemicals from BUCHI are designed and elaborated to achieve reproducible and reliable results. A crucial factor for reliable results is the correctly prepared boric acid receiver solution. The BUCHI boric acid solution contains the right amount of indicator in a 2 or 4 % boric acid solution with adjusted pH for potentiometric and colorimetric titrations.

SpeedDigester K-439
The SpeedDigester K-439 revolutionizes IR digestion. It combines the benefits of IR and block digestion in one unit. Fast nitrogen determination by Kjeldahl digestion at controlled temperatures enables an increased sample throughput. Multiply the instrument functionality whenever needs are changing.

SpeedDigester K-425 / K-436
Set new standards in terms of digestion speed, flexible use and result reproducibility with the IR SpeedDigester. Achieve an increased sample throughput for nitrogen determination by Kjeldahl digestion and multiply instrument functionality whenever needs are changing.

KjelSampler K-376 / K-377
The KjelSampler K-376 or K-377 in combination with the KjelMaster K-375 meets upmost demands in high throughput Kjeldahl determination. The system provides a maximum degree of automation and flexibility.

Distillation Unit K-350 / K-355
Perform Kjeldahl nitrogen or protein determinations compliant to officially approved methods in the most cost effective way. Expand your range of applications with the additional features of the K-355.

Consumables for Digestion
Perform Kjeldahl nitrogen or protein determinations compliant to officially approved methods in the most cost effective way. Expand your range of applications with the additional features of the K-355.

Consumables for the Scrubber
The absorption stage of the scrubber holds back most of the undesired particles by means of granules of activated charcoal or a universal adsorption granulate. It also enables the aerosols to recondensate.

Solutions

Solution «Kjeldahl Throughput»
You cope with ever increasing sample loads for nitrogen determination according to Kjeldahl, with rising costs per analysis and requirements for thorough documentation. We offer a solution for analyzing up to 120 samples in a one-person working day, providing a maximum degree of automation in sample and data processing.
