K9840 vs K9860 vs K1100 vs K1160: Which Kjeldahl Analyzer Fits Your Laboratory?
Choosing a Kjeldahl analyzer starts with a practical question: which part of your testing routine needs to become easier?
Some laboratories need automatic distillation while keeping their existing titration procedure. Others want integrated titration, shorter analysis cycles or fewer manual interventions between samples.
The K9840, K9860, K1100 and K1160 address these different priorities. Their applications overlap; the main distinction is how they fit into your daily workflow.
Compare the Four Models at a Glance
| Model | Main difference | Typical application scenario | Choose it when… |
| K9840 | Automatic distillation without integrated automatic titration | Teaching laboratories, occasional nitrogen testing, laboratories with an established separate titration procedure | You mainly need to automate distillation |
| K9860 | Integrated automatic distillation and titration; specified analysis time of 5–10 min/sample | Routine food, grain, flour and feed quality control | You want automatic titration for everyday testing |
| K1100 | Integrated titration with a shorter specified cycle of 3–8 min/sample | Laboratories receiving samples frequently throughout the working day | Faster measurement turnaround is a priority |
| K1160 | Finer titrant dosing increments, lower specified cooling-water consumption and optional batch sample handling | Central laboratories, testing services and production laboratories processing repeated sample batches | You want to reduce hands-on work and plan for batch automation |
Specified analysis times exclude sample preparation and digestion and depend on the method.
