Laboratory Units

From feasibility testing to small scale production

With laboratory units, reliable conclusions about the feasibility of a distillation process can be made by using only small product amounts. The set-up and design of our lab units is based on many years of experience gained in our own test center. The key components in lab scale systems are fabricated in borosilicate glass. This enables observation of product properties like foaming, fouling and film distribution on the heated shell during distillation.

Why laboratory units?

Feasibility testing for new distillation tasks and products

 

Production of samples up to several kilograms

 

Determination of achievable product quality and yields

 

Required raw material quantities about 1 - 3 kg

 

Determination of process parameters

 

MOC of evaporator: Borosilicate glass

 

"High evaporation rates within a single process path are possible"
