FOSS service and support

More than just an instrument, FOSS solutions are supported by a global network of more than 250 highly trained service engineers.

FOSS Support

Digestor™ 2508 & 2520

Fully automated digestors for safe Kjeldahl analysis

FOSS Tecator line Digestion systems are based on a digestion unit and a tube rack, allowing fully automated digestion for convenient, safe and flexible Kjeldahl analysis. Two way PC communication supports traceability and GLP. These versatile digestion systems are capable of handling eight, twenty or forty tubes in volumes of 100 ml, 250 ml or 400 ml dependent on chosen configuration.

Parameters

Kjeldahl digestions, Chemical Oxygen Demand & other reflux chemistries, Trace metal analysis by AAS or ICP instruments

Sample types

Raw materials and finished products in Food, Feed, Agriculture and related matrices, Water & Wastewater and a wide range of industrial compounds
Laboratory solutions

Method/principle of analysis

In Kjeldahl digestion the aim of the digestion procedure is to break all nitrogen bonds in the sample and convert all of the nitrogen into ammonium ions. One-two grams of pre-ground sample are accurately weighed to four decimal places, and placed in a digestion tube in a tube rack.

Laboratory solutions

Automation levels

The auto digestion systems are available in two versions: Auto Lift and Auto Rack. Auto lift systems facilitate highly automated procedures to eliminate handling of hot chemicals. Auto Rack system involve more manual operation. The Auto Digestors can be combined to match individual needs, from units capable of handling just a few samples a day up to fully automated system for high sample throughput.

Laboratory solutions

Exhaust and scrubber

All models are delivered with a Tube Rack with integrated heat shields. They should always be combined with a matching Exhaust Manifold designed for each Digestion Unit facilitating fume removal, or Reflux Head and Test Tubes – 100 ml, 250 ml or 400 ml volume. For Kjeldahl digestions the 2501 Scrubber Unit should always be considered for safe and efficient neutralisation of corrosive gases. This replaces the water aspirator, supplied as standard.

Software

Auto systems have memory for up to 127 FOSS Applications and 127 User Applications together with RS232 as standard and the option of Bluetooth functionality. The communication and application software is delivered with the system in CD ROM format. There are currently more than 80 FOSS applications in the CD Library supplied.
