Wiped Film Evaporator Video - How clearSTILL Works

What is clearSTILL?

clearSTILL is a two-stage wiped film distillation machine that performs two independent distillation passes in a single contained cycle. The output can be used fto manufacture any product category. It supports throughput capacity of 4-6L per hour while doubling throughput and labor efficiency over single-pass machines. clearSTILL provides the best solution for opening the production bottleneck created by conventional wiped film distillation machines while lowering labor costs.

Programmable methods enable automated GMP process control with reporting, and GMP certified stainless-steel materials support global market requirements.
