Kjeldahl digestion unit: Reproducible, transparent and traceable digestion acc. to ISO 17025

New: The successor models KT and KT-L for up to 40 simultaneous Kjeldahl digestions replace the proven digestion system KB and convince with unique product characteristics and functions.

The C. Gerhardt digestion blocks are perfectly adapted to the needs of accredited laboratories and ensure the validity and reproducibility of the analysis results by automating and documenting the process steps.

Ideal for subsequent Kjeldahl distillation with the VAPODEST® distillation units.

Different models available up to the top model, the KT-L, which is a future-proof investment through state-of-the-art technology.



Reproducible digestion conditions

The precise temperature/time control ensures a secure digestion process.

Meets the requirements for analysis results of international standards, e.g. DIN/EN/ISO, AOAC, EPA, ASTM, EU regulations, APHA, VDLUFA, GAFTA and Ph. Eur. 2.5.33 method 7, Procedure A.

Transparency of results acc. to ISO and GLP

The world-wide unrivaled combination of inspection window and illuminated digestion area enables permanent monitoring of the digestion process.

The data are documented in accordance with QM standards, e.g. ISO 9001, ISO 17025 and GLP. This makes the KJELDATHERM the only digestion block to support the user with the complex requirements for the data management of the QM standards.

Convenient and safe

The motorized multi-level console (KT-L) enables convenient and safe lifting and lowering of the loaded rack.

The exhaust manifold and water jet pump provided or the powerful (optional) TURBOSOG or VACUSOG scrubber ensure effective extraction of acid fumes.

The digestion data can simply be exported, e.g. to a LIMS.

High ease of use during digestion

The 3.5" (KT-L) or 2.5" (KT) color display is unique on the market and convinces with a clear user interface. The self-explanatory symbols also facilitate the operation.

Standard Kjeldahl methods are predefined and can be operated by the user easily. A further 99 methods, each with 40 temperature/time programs can be stored on the device.

Efficient workflow

Due to the high degree of automation of the KT-L models, the user only has to insert the samples and start the digestion process. The device executes the digestion autonomously with the recording of all relevant data. In this time the user can perform other important tasks.

Another innovation is the individually adjustable heating capacity which allows for greater flexibility during digestion of difficult samples.

Highest quality for high demands

The cover plate around the heating block as well as all other relevant parts are provided with a special coating. As a result, they are protected against aggressive chemicals and heat even after years of use. The particularly smooth surface allows easy and thoroughly cleaning in the shortest possible time.

An all-round heat shield is used to prevent injuries even in a bustling laboratory day.
