Description
FOSS Kjeldahl distillation unit KJELTECH 8100 Foss Denmark
This Kjeldahl distillation unit provides a simple and reliable solution for safe, semi-automated distillations according to the global reference method.
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.
Overview of Kjeltec™ models
The Kjeltec™ series consists of four models: Kjeltec™ 8100, 8200 and 8400 and KT 200 Kjeltec™ with different levels of automation.
