Saves us a lot of time and work.
Rating: 4.7

  • Application Area:Determination of the water content for lyophilized matrix products

"After a short training period, every new employee can operate the system independently. A contact person is available for every type of problem or question and takes time for answers and solutions. Different matrices are filled in 3 different sized containers and lyophilized. Since the sample throughput was getting bigger and bigger, we switched from an old, manual system to an automated measuring system. The rushes are very good and reproducible, giving employees more time for other work."

High accuracy results when using the proper parameters
Rating: 3.3

  • Application Area:Analysing moisture content in polymers

"The quality is OK and the results are reproducible if you are always following the same procedure and taking into account the time for preparing the samples - by changing one of the parameters in the method, you could get different results. The equipment is easy to use once you have practiced several times. We had some troubles with after sales care and technical support - not all of the staff we spoke to have same level of knowledge of this technique and this affected us a lot. Regarding value for money, all laboratory equipment is expensive and maintenance contracts are expensive as well."

Great equipment at a low price with very low maintainence.
Rating: 5.0

  • Application Area:Check water content of concentrated hydrofluric acid

"The price of all metrohm instruments aree market competetive. So it's very difficult for us as a company to try other instruments or give them a chance. The brand has been in business so long, the price, ease of use and reliability, make it very difficult for us to choose one of Metrohm's competitors. We chose metrohm for the following reasons: price, reliabilty, ease of testing, easily available spares, low maintainence, easy to maintain, easy to program and run, no electronic issues, easy to train staff, durable, good after sales service, price is very reasonable when servicing equipment. All in all, we go for price, reliabilty and quick turnaround time for testing of samples."
