Description
Samples like Lubricating oil may include elements that can interfere with the Karl Fischer reaction and moisture measurement by direct methods are difficult.
The EV-2000L Oil Evaporator utilizes azeotropic distillation solvent like toluene or xylene, thus saving on Karl Fisher reagents.
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.
