Short Path Evaporator KV 80
Short Path Evaporators are used in chemical industry for the production and processing of macro-molecular substances. Because of the thermal sensitiveness of products, this separation method is applicable. The sample to be distilled is exposed only for a very short time to the heating substances because the film, created by the wiper, can evaporate very quickly. The residence time of medium on the heating surface is a matter of seconds, thus essentially less than in a reboiler flask, circulating evaporator etc. The evaporated product (operation pressures down to 10-3 mbar and temperatures up to about 300°C) has to pass a “short path” to the condenser only, which is located in the middle of the evaporator.
Evaporators in borosilicate glass 3.3 are available with heat exchange areas 0.02…0.8 m².
Evaporators in stainless steel can be heated by a heating jacket to higher temperatures with more heat transfer area for higher throughputs.

Features & Benefits
- Short Path Evaporators are utilized in the chemical industry for processing macro-molecular substances, particularly suitable for thermally sensitive products.
- The method involves exposing the sample to be distilled for a brief duration to heating substances, facilitated by the rapid evaporation of the film created by the wiper.
- The residence time on the heating surface is significantly shorter, measured in seconds, compared to traditional methods like reboiler flasks and circulating evaporators.
- The evaporated product, operating under pressures as low as 10-3 mbar and temperatures reaching around 300°C, efficiently travels a “short path” to the centrally located condenser within the evaporator.
- Evaporators in borosilicate glass 3.3 are available with heat exchange areas ranging from 0.02 to 0.8 m².
- Stainless steel evaporators, equipped with a heating jacket, offer higher temperature capabilities and increased heat transfer area to accommodate larger throughputs.
