Key features:

  • Safety features

A fast tube draining system removes the need for handling hot reagents after distillation. Interlocked safety door which must be closed with a tube in place before the unit will operate. Cooling water flow is controlled automatically and a temperature sensor stops the unit if the distillate is too hot. Sensors monitor tube in place, safety doors, reagent levels, water level and over-pressure in the steam generator providing safe use.

Key features:

  • Unmatched Accuracy

The superior performance of a KjeltecTM titration system is based on colorimetric measurement of a precise chemical reaction for end-point detection. Accuracy is assured time after time with the additional benefits of long-term stability, wide working range, speed and simplicity without the need for repeated and costly calibration procedures.
 

  • Safety features

A fast tube draining system removes the need for handling hot reagents after distillation. Interlocked safety door which must be closed with a tube in place before the unit will operate. Cooling water flow is controlled automatically and a temperature sensor stops the unit if the distillate is too hot. Sensors monitor tube in place, safety doors, reagent levels, water level and over-pressure in the steam generator providing safe use. 
 

  • Autosamplers

An optional 20 or 60 place Autosampler provides the benefits of automation even at lower sample throughputs. Just load your sample racks directly from the digestion block and KjeltecTM will perform accurate analysis unattended for more than four hours.

Key features

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.

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.
