Each pressure reactor is the product our experience in pressure vessel design and construction, gained in over 25 years.

The Microwave Digestion System with unique, optical temperature and pressure monitoring of each individual sample during Acid Digestion.

Patented optical procedure to measure the temperature and pressure of each individual sample guarantees active and dependable reaction monitoring. The sample material never comes into contact with sensors or probes. Complicated connection of sensors to sample vessels is totally eliminated.

Pressure digestion vessels from Berghof are the systems of choice when it comes to difficult samples, large sample masses, or in labs that value high levels of flexibility. Typical digestion times lie in the range of 2-4 hours. For difficult to digest samples (e.g., SiC), the ability to extend digestion time for practically any desired period represents a decisive advantage. Microwave units cannot be employed for such applications. An additional advantage over microwave systems lies in the fact that larger sample quantities (e.g., 2 g organic samples) can be digested because of the larger available pressure range up to 200 bar / 2900 psi.

The Berghof easyH2O analyzer selectively determines the water content in a sample by means of thermo-coulometric determination. For this purpose the sample is heated up in a closed sample chamber and the evaporated water is conveyed to the sensor. Unlike the gravimetric moisture-measuring techniques, the result is not distorted by substances which evaporate out of the sample together with the water. The Berghof easyH2O delivers reproducible and exact results. It facilitates separate identification of free surface and capillary water as well as bonded water. Even strongly bonded water is released and quantified by means of temperature programs up to 400°. The results correspond to those of a Karl Fischer titration.
