For dependable and reproducible hydrogenations

The Buchi hydrogenator is a turnkey hydrogenation solution, consisting of:
• bpc 2 (Buchi pressflow controller) for hydrogen dosing, control of reaction pressure and continuous measuring of the Hydrogen uptake until saturation
• Buchi pressure reactors, offered in different materials and volumes for high to low pressure applications
The unique volumetric dosing system of the bpc 2 features outstanding reproducibility, dosing accuracy and measurement of gas consumption over a wide range. This robust technology is based its precursor bpc, which has proven its reliability and performance in research, scale up, process development and optimization as well as in small scale manufacturing plants of Pharmaceutical and Fine Chemical companies worldwide. It is often used for catalyst testing, in polymerizations also.

The Buchi complete solution fulfills highest safety standards for hydrogenations under low and high pressure and makes it a very reliable system. Multiple built-in safety features as built in gas leakage sensors can trigger an immediate shut down of the gas supply.

The reactors can be prepared for catalytic hydrogenations by different solutions as for catalyst charge and exposure as well as for gas entrainment. The reactors design and accessories enable control of exothermic reactions.

The bpc 2 instrument is easy and safe to operate. The hydrogen uptake is continuously measured and recorded until saturation or another predefined limit is reached. The progress of the reaction is shown graphically.

The unique volumetric dosing enables high accuracy over a wide range by 2 possible control modes:
• constant reaction pressure
• constant flow rate

VD: Volumetric Dosing of hydrogen: <br/>safe, precise, reliable

VD: Volumetric Dosing of hydrogen:
safe, precise, reliable
