DT 208 & 220 Digestor™

Manual digestor blocks for effecient Kjeldahl analysis

The Labtec DT 208 & DT 220 basic Digestion systems for Kjeldahl analysis consist of a digestion unit and a tube rack. The digestion units are insulated to minimise heat transfer to the surroundings and allow fast, even heating, thus giving good working conditions as well as saving energy. They are designed for batches of either eight (DT 208) or twenty test tubes (DT 220).

The Labtec Digestors have a built in, user definable, time and temperature controller and display. The temperature and time for the digestion are selected on the front panel. All other procedures, including operation of a connected scrubber, are then performed by the operator once the digestion unit has reached the selected temperature.

The unit can be upgraded with a range of accessories that reduce handling hazards with minimum bench space, such as a manual lift system to position the tube rack, Scrubber and exhaust above the digestion unit.

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.
