FOSS - Protein Analyzer - KT 200 Kjeltec™

The KT 200 Kjeltec™ Distillation unit provides a simple and reliable solution for safe and semi-automatic distillation for protein determination. The possibility to pre-program alkali addition and distillation time supports the production of accurate results independent of operator.


Simple, safe and reliable analysis according to official standards for accurate results independent of operator.

Key features

Improving safety

A high accuracy bellows pump gives long term stability in delivery of the alkali. The unit is equipped with a wide range of safety features including safety door, plus level pins and overpressure sensors for the steam generator. The door completely covers the area in front of the operator and the unit cannot be operated with the door open. The drip tray can easily be removed for cleaning.

Approved method

Official and accurate procedures (ISO, AOAC, EPA, DIN) simplify validation.

SAfE Technology

The patented SAfE* technology improves safety by a mixing procedure, reducing the exothermic reaction between alkali and acid during distillation and removing the need for manual pre-dilution.

*Steam Addition for Equilibration

Foss Analytical

FOSS creates end-to-end solutions that secure and improve food quality. From raw material to finished product. Our analysis instruments refine measurements into information management that enables businesses to run intelligent data-driven productions with less waste and bigger yields. Controlling cost and quality across all sectors and value chains, we help food and agricultural producers limit the number of human errors, scale their business faster and reduce manual labor as well as labor costs. We call it analytics beyond measure.

We cover these food and agricultural industries: Dairy, Feed and Forage, Grain, Flour Milling & Oilseed Processing, Laboratories, Meat, Raw Milk Testing and Wine.

Over the last 60 years, we have made it our business to define the standard of analytical solutions for the food and agricultural industry. We pioneered advanced analysis for the challenging production environments in the 1960’s, and we were the first to integrate chemical composition analysis in process lines. Now our resolve and ambition have also made us the international benchmark in the field of chemometrics and real time analytics.
