Wiped film and short path distillation units for laboratory use

With laboratory units, reliable conclusions about the feasibility of a separation process can be made by only using small product amounts.
The set-up and design of the lab units VTA offers to customers is based on the experience gained in our own VTA test centre for years.

Laboratory Units

Lab units are used for

  • Verifying the feasibility of a separation task
  • Doing first process development steps
  • Producing small sample amounts of final product
  • Optimizing existing processes
