EV-2000L Oil Evaporator for Karl Fischer Titration
EV-2000L Oil Evaporator for Karl Fischer Titration
Description
The EV-2000L Oil Evaporator is a unique accessory designed exclusively for Karl Fischer titrators, allowing accurate determination of trace moisture in lubricating oils and other complex hydrocarbon samples. Unlike other systems, the EV-2000L uses an azeotropic distillation method that separates water from oils using n-octane instead of hazardous solvents like toluene or xylene.
Why the EV-2000L is Different
-
Exclusive to JM Science / Hiranuma systems – no other Karl Fischer manufacturer offers a comparable accessory.
-
Manual or fully automated – available as a standard unit or as an automated model with 20-position autosampler, ideal for high-throughput labs.
-
Improved accuracy & reproducibility – eliminates interference from oil additives such as detergents, dispersants, and anti-oxidants, which can otherwise deteriorate the KF anode solution.
-
Environmentally safer – uses n-octane, a lower-hazard solvent, reducing environmental and health risks while maintaining accuracy.
-
Lower operating costs – reduces frequency of exchanging KF reagents by minimizing anode solution deterioration; when paired with a fritless (single-cell) KF setup, it also reduces cathode solution consumption.
Applications
The EV-2000L is particularly valuable for:
-
Lubricating oils (engine, hydraulic, gear oils)
-
Petrochemicals & fuel additives
-
Greases & specialty oils
-
Quality control in automotive and industrial labs
By combining Karl Fischer titration with azeotropic distillation, the EV-2000L enables accurate, reproducible water determination even in heavily-additized oils — something traditional KF titrators cannot achieve.

Frequently Asked Questions (FAQ) – EV-2000L Oil Evaporator
Q1. Why can’t standard Karl Fischer titrators measure moisture directly in oils?
Lubricating oils and greases often contain additives (detergents, dispersants, antioxidants) that interfere with the Karl Fischer reaction and rapidly deteriorate the anode solution. The EV-2000L avoids this by separating water from the oil sample using azeotropic distillation.
Q2. What solvent does the EV-2000L use?
The system uses n-octane as the azeotropic solvent. It is safer than toluene or xylene, and it efficiently extracts water from oils for accurate titration without introducing hazardous conditions.
Q3. What types of samples can the EV-2000L handle?
It is designed for lubricating oils, greases, petrochemical samples, and fuel additives. It’s widely used in QA/QC for automotive, industrial, and energy research laboratories.
Q4. How does the automated EV-2000L improve efficiency?
The automated model features a 20-position autosampler, allowing unattended operation. Labs can load multiple samples and run them overnight or during the workday, freeing technicians for other tasks.
Q5. What is the main advantage of the EV-2000L compared to competitor systems?
No other Karl Fischer titrator manufacturer offers an oil evaporator accessory like this. It combines the accuracy of KF titration with azeotropic distillation, providing unique capability for oil and lubricant testing.
