The Hiranuma EV-2000L Oil Evaporator manufactured in Japan utilizes azeotropic distillation (Micro Dean & Stark Distillation). It completely separates water from sample matrices, thus eliminating any side reactions with interfering substances. The EV-2000L can be used with all HIRANUMA Karl Fischer titrators, or any other manufacturer's titrators.
