Overview

Benefits

Range of applications

Steam volatile compounds such as alcohol, TVBN, volatile acids or phenols are separated best by gentle distillation under reduced steam power.
Nitrates or nitrites are conveniently reduced in-situ using programmable optional reaction steps.
Automated dosage of strong acids such as phosphoric acid directly into the distillation tube yields exhaustive distillation of SO₂ or formaldehyde.

Convenient and reproducible

50 personalized methods for various sample matrices featuring steam regulation, reduction and dosage of strong acids. Ready-to-use BUCHI approved Application Notes guarantee reproducible operation.
Communication with a wide variety of titrators reduces manual operation, enables documentation and LIMS integration.
Prevention of carry-over even of strongly foaming samples thanks to the dedicated Devarda splash protector.

Flexible and safe

Quick and easy switch between Kjeldahl and direct distillation without laborious reconnection of chemical tanks.
No manual addition of harmful chemicals. Automated cooling media control.

KjelFlex K-360

Accessories

Options

Glass splash protector

With its extensive know-how BUCHI provides state-of-the-art glass parts like the splash protector. The whole distillation process is visible for easy method development and process monitoring.

Plastic splash protector

This splash protector is made of glass fiber reinforced polypropylene. It is the choice for high throughput analysis due to its long lifetime.

Titration set

Different titrator models can be connected to the KjelFlex K-360 to increase the level of automation. With the titrator connected the titration step is triggered automatically when the distillation is complete.

Acid resistant pump

Some non-Kjeldahl applications require the addition of an acid to the sample prior to the distillation process. With the optional acid resistant pump adding the acid can be automated.
