Kjeldahl Distillation Units

Automatic Kjeldahl Distillation System:

The K series Kjeldahl consist of three models: K9840, K1100, K1100F with different levels of automation.

K series features including various generator, pumps and valves for quantified liquids, cooling water and distillate temperature control, solutions adding, emptying tubes and pips and washing.


K9840 is an automatic Kjeldahl distillation device.


1. External connecting titration device, including colorimetric or potential titration device;

2. Manual or automatic mode changeover free;

3. 4.3 inch color screen;

4. Solutions adding are quantified;

5. Multi protection, safety door, tube position, cooling water testing, etc.

6. Self-trouble shooting functions for valves, pumps and sensors.

7. Tube and pips automatic emptying and washing.


K1100 and K1100F are automatic Kjeldahl Analyzer, consist of distillation, titration, calculation, data treatment. The differences between two models: K1100F adopt 300ml digestion tube, available titration while distillation; better ARM operation system and more methods editing.


1. Built-in colorimetric titration device;

2. Two steam models, can adjust solutions adding's sequence, for distillation and absorption special samples;

3. Touch screen used for operating and display;

4. Built-in printer, USB and series port for data outlet,

5. Samples' methods can be edited and store

6. Almost features of K9840 plus;
