Molecular wiped film short-path distillation
Wiped-film evaporator for short-path and molecular distillation
The new flagship for short path and molecular distillation. The SP 1000 CC is a turnkey ready system for laboratory use and small scale production and is optimized to cover nearly all applications, from high melting to high boiling points and can handle thermal sensitive material, with full flexibility and complete continuous operation.
The molecular distillation, also called high vacuum wiped film, thin film or short path distillation, is a well-known process to separate thermal sensitive material in a very thin film at a high vacuum and short distance to the condenser, which allows an unbeatable performance.
The SP 1000 CC is equipped with a unique and patent pending HYBRID-evaporator which combines all positive aspects of glass and stainless steel in one instrument. It is reliable and solid like stainless steel, but with the full visibility of a glass still.
Due to its complete heated inlet and outlet lines in combination with our tempered feed- and discharge pumps, melting points >150°C can be easily handled.
The sophisticated vacuum system is able to handle incondensable volatiles with its dry running chemical resistant scroll pump as well as the air cooled diffusion pump can reach a system pressure down to 0.00001mbar.
Due to the fully vacuum tight feed and discharge system there is no limitation in the charge or receiver vessel size and the system can run up to 24/7 operation without any interruption in the vacuum process and a throughput up to 7l/h.
