HIRANUMA Oil Evaporator EV-2000L

The EV-2000L Oil Evaporator utilizes azeotropic distillation.
It completely separates water from sample matrices, thus eliminating any side reactions with interfering substances. The EV-2000L can be used with all — Karl Fischer titrators, or any other manufacturer’s titrators.
