Product description
AQUA 40.00 Basic Module – Compact, Fast, and Highly Precise
The AQUA 40.00 Basic Module offers rapid and precise determination of water content in liquid samples and gases. Thanks to its compact design, it requires minimal space in the laboratory.
Samples are easily injected through a septum directly into the measuring cell.
The cell’s optimized design ensures extremely low background drift, making the titrator ideal for trace-level moisture analysis.
Titration speed is automatically adjusted based on the actual water content, thanks to continuous control of the electrolysis current – resulting in very short analysis times.
The AQUA 40.00 Basic Module is highly flexible:
- It supports all common Karl Fischer reagents.
- In many cases, a diaphragm is not needed in the generator electrode, allowing the use of a single coulometric reagent.
Flexible Expansion Options
The system can be easily upgraded to the AQUA 40.00 Vario, enabling moisture determination in all types of samples using headspace technology.
For applications requiring high temperatures (up to 1300 °C), the AQUA 40.00 Basic Module can be combined with the High Temperature Oven HT 1300.
Applications
The AQUA 40.00 Basic Module is suitable for samples that can be dosed directly into the titration cell, e. g.
- Solvents
- Oils and fats
- Fuels, biodiesel
- Hydraulic and brake fluids
- Gases
Advantages
- No sample preparation
- Dosing by syringe directly into the titration cell
- Very short analysis times
- Suitable for all common Karl Fischer reagents
- Basic Module with low space requirement
- Additional modules available for different sample types
