Aquamax KF Plus titrators have been specifically designed for the determination of water content, combining coulometry with the Karl Fischer method. The versatile Aquamax KF Plus is suitable for a wide range of applications and offers many advantages including a tough measuring vessel, a ‘press go’ keypad and built-in printer.

Small footprint - enclosed parts
The Aquamax KF Plus and Aquamax KF Portable are both small footprint instruments with all parts enclosed,
designed to save lab space and allow for easy transportation from the lab to the sampling point.
The instruments built in battery allows for use outside of the laboratory,
the back of the truck or mobile lab,
or in areas where electrical mains stability is not available.
Water check button and syringe
Water check
The µg check button allows the operator to simply press go, inject 1 µL or maybe 10 µL of distilled water (as required by some ASTM methods) and verify if the instrument and reagent are working with in their required specification. The µg check overrides the programmed calculation and displays/prints out a report of the verification check. The coulometer then automatically reverts to the pre-programmed setting.
Tough Measuring Vessel
The unique LDC glassware design is by far the easiest to use and the most robust. The electrode locking system allows the joints to seal completely, without the use of grease or PTFE sleeves, and provides improved baseline stability. Hassle free assembly and disassembly.
Gas tight sampling syringes
Each Aquamax KF is supplied with a white lettered gas tight sampling syringe and luer needle which has been designed specifically for accurate sampling of oils and fuels.
The AQUA 40.00 Vario combines the Karl Fischer Titration with the headspace technique. This offers a wide range of interesting applications to determine moisture in solid and pasty samples, oils and viscous compounds.
The sample preparation takes place using the dynamic headspace technique. The sample - in a closed vial - is placed into the headspace oven and tempered.
A closed-loop gas circulation with dry carrier gas flows across the sample and transports the extracted water completely into the measuring cell, where the analysis is carried out by titration according to the Karl Fischer method.
It does not require time-consuming sample preparation:
Weigh out the sample into the headspace vial and close it
Place the vial in the device (manually or automatically)
Prepare the measurement and start it
Advantages
Reduced reagent consumption
No evaporation of methanol from the reagent
Additional gas drying is not required due to closed-loop circulation of extraction gas
Stand-by titration for automatic conditioning and easy blank tests
Short measuring times, even with complicated samples
Suitable for 2 R - 50 R vials
Easy automation with autosampler
Uniquely: the closed-loop circulation of extraction gas
Closed-loop gas circulation
The system has the unique advantage of circulating the extraction gas in a closed loop. Any additional gas drying is not necessary. The internal carrier gas for the extraction is continually titrated to dryness within the closed loop. The total dryness of the gas enhances the moisture release from the sample. Sensitive samples can be heated out very gently. All these advantages result in reducing reagent consumption considerably.
AQUA Vario PLUS - automatic version with sampler
Automated version
With the autosampler, the manual device is easily transformed into a fully automatic version. The system can be quickly and conveniently adapted to different vial sizes - simply change the oven insert and/or sample plate for the autosampler. Predefined methods contain all settings for the sample vessels and the device configuration.
Product Features
Configurable temperature programs
Automatic identification of interchangeable oven and sample plate of the autosampler
Priorized express samples can set individually by user
Software complies with requirements of FDA to 21 CFR Part 11 (Software with user-specific access, routine methods for individual and definable user levels, profound documentation and archiving of all measured data)
