Kjeldahl Digestion at Turbo Speeds Using Infrared

Heat up to 12 Samples to Boiling Point in Just 10 Minutes

Sample preparation for Kjeldahl analysis does not need to be as time-consuming as it often is. TURBOTHERM lets you prepare samples quickly, safely and flexibly. The samples are heated fast and cooled down just as quickly after switching off the infrared source, allowing you to proceed directly with the next processing step. Unlike other systems, TURBOTHERM measures the temperature directly between samples, giving you an overview of the exact digestion conditions.

Benefit from 130 years of experience in constructing equipment for Kjeldahl analysis. At C. Gerhardt you will find the Kjeldahl solution you need, whether it is a classical apparatus for the smallest of quantities or a fully automated system.
