Rápido y fiable Fast & Reliable
Rating: 4.3

  • Application Area: Contenido en agua en aceite lubricante usado Water content in used lubricating oil

"Equipo fácil de usar e intuitivo. Logramos resultados fiables, repetitivos y reproducibles, testado con material de referencia. Al principio cuesta un poco elegir la temperatura de ensayo y peso idóneo de muestreo para nuestro rango de trabajo, pero una vez configurado el equipo el manejo es super rápido. Si las muestras son susceptibles de tener un alto contenido en agua el tiempo de ensayo es muy alto, para contenidos en agua en torno a 500 ppm a 140ºC el tiempo se ensayo es de unos 30 min aprox. Una vez finalizada la medida el equipo te avisa con un sonido, es muy práctico, porque puedes hacer otras actividades mientras el equipo está midiendo. Easy-to-use and intuitive equipment. We achieve reliable, repetitive and reproducible results, tested with reference material. At first it is a bit difficult to choose the ideal test temperature and sampling weight for our working range, but once the equipment is configured, the handling is super fast. If the samples are likely to have a high water content the test time is very high, for water contents around 500 ppm at 140ºC the test time is about 30 min. Once the measurement is finished, the equipment warns you with a sound, it is very practical, because you can do other activities while the equipment is measuring."

Great instrument every labs should have one
Rating: 5.0

  • Application Area:analysis of Peptide API Samples to determine water content

"KF Coulometer is good for handling and results are also reproducible. It is used for low water content samples . KF coulometer is easy to use in daily routine, space saving because it works without PC and high quality for less money in compare with others just having problem with connecting the scale via USB easy to learning for new user .Hardware is also good material."

Machine works ok but many issues
Rating: 2.7

  • Application Area:Measuring water content in a variety of samples

"The equipment is easy to use and sample prep does not take up too much time, however the variety of issues that I have had with the equipment outweighs its usefulness, and there is a list of error codes in the handbook which describe some errors that may occur but no real aid in fixing them. Admittedly one of the reoccurring issues is to do with an external standard, but we've been told by engineers that the machine is working perfectly when it is not."

Top notch kit.
Rating: 5.0

  • Application Area:Determination of water content in APIs pre and post formulation

"The equipment is straightforward to use from a basic user level, creating a new method is simple and the result reproducibility is strong. These points in tandem make our method development process a dream. I would highly recommend this product for any Laboratory that is looking to measure water content."

Easy to use and a must have for our lab.
Rating: 4.7

  • Application Area:water content

"The materials we test cannot be directly injected for Karl Fischer measurement of water content, and this oven makes it possible. We looked at ovens from other companies, but their design made no sense, particularly if you want to measure very small quantities of water. This was really the only reasonable option. The oven is very straightforward to use, and comes with great technical support. It's expensive, but the only design we found worth purchasing."

Accurate and precise results for bioresorbable polymers!
Rating: 5.0

  • Application Area:R&D and GMP manufacturing analyses - water content in bioresorbable polymers

"Bioresorbable polymers are degraded by hydrolysis, therefore the water content is of great importance from an R&D, GMP and Quality standpoint, especially in the biomedical and medical device industry. Using the 860 KF Thermoprep we can achieve precise and accurate results, giving us a lot of confidence and reproducibility in our analyses. It is easy to use from technicians to scientists, very easy to clean and keep the maintenance in order thanks to the guidance and support from Metrohm UK Technical support, they have helped us from method optimization to troubleshooting. I would definitely recommend this device and the technical service, with this combination you should have your equipment up and running in no time and you will start doing analysis before you know it."

Good investment and addition to our analytical facility
Rating: 4.3

  • Application Area:Polymer, nanocomposites, composites, dielectric fluids

"The installation of the equipment is very simple and straight forward and requires low maintenance. The temperature control is very precise, and the system could be ready for sample analysis in very quick succession. Building a temperature method is very simple and the available brochures and manuals for guidance are properly described for the user. The equipment has a small footprint on the lab desk, which is admirable to accommodate in small space. I didn't like the display screen on the equipment. It is very dark and has no backlight for illumination. That should be improved. A proper keypad is also recommended to have in next version of the equipment. There is a plastic connector fitting for gas purging which should be replaced by metal connectors for better durability. On the first day the plastic connector fitting was broken at our site and we couldn't use the equipment for at least a month while waiting for the replacement. Another request to Metrohm would be to reduce the price of the sample vials to an affordable range as it is now very expensive."

"This unit has been very useful in the laboratory. The service from the vendor has been excellent. As with most new equipment, the ease of use can be directly related to training and involves a learning curve."

Thermal sample preparation in Karl Fischer titration.

For various reasons many substances are not suitable for a direct Karl Fischer titration:

– They release their water only slowly
– The water is released at high temperatures only
– The substances are poorly soluble in alcohols
– They undergo side reactions with KF reagents
– They contaminate the titration cell or the electrodes

By using the KF oven method the above-mentioned problems can be avoided. The substance under investigation is heated in a hermetically sealed vial in the oven. The water vapor released is transferred to the titration cell by a carrier gas. This means that no noxious solubilizers have to be used, side reactions as well as matrix effects are absent and the contamination of the titration cell is avoided.

Depending on the sample’s water content, the determination can be carried out either by coulometric or volumetric Karl Fischer titration.
