Vapodest 30S Programmable Distillation Systems Gerhardt

Vapodest 20S & 30S Programmable Distillation Systems Gerhardt

Gerhardt has been offering the rapid distillation systems VAPODEST for the steam distillation of Kjeldahl digestion and other samples. The new VAPODEST models offer a state-of-the-art technology. All models have a modern MCU-control, automatic steam generation, RS 485 interface, a corrosion free plastic housing and many more features.

All distillation systems are especially good in handling distillations of Kjeldahl digestion solutions as well as physical seperation methods of water steam soluble materials and volatile acids. For the determination of alcohol it is ideal that the steam power of the steam generator can be reduced to around 70 %. Best results in combination with digestion systems KB, CSB und SMA.

The models offer varying degrees of automation with manual end point titration
