905 Titrando - Titrator with Dosing Unit by Metrohm AG

"Perfect equipment for precise titrations. In our lab, we use it to determine stability constants of metal ion-peptide complexes. Don't really know how after-sales care works because during the last 5 years titrator never required service. It works very well, results are repeatable and precise. Tiamo software is user-friendly and easy to use. I like it for full automatization and a broad selection of measurement parameters. Strongly recommend it!"

"The 905 Titrando is a valuable part of the QC lab, carrying out many titrations every day. Once set up, it is very quick and simple to use. Compared to manual titrations, the autotitrator gives much more accurate and repeatable results."

"Reproducible results. Great intuitive user interface. Technical support is very good when required. After sales care has been great, we have been allowed to borrow probes before to test if they will fix problems before we buy."

"Great titrator with superb repeatability. Very reliable, no breakdowns in over 5 years of use. Methods with calculations are programmed in so analysts just need to press a button to start the titration."

"It is an easy-to-use piece of equipment, which provides reliable results."

"Easy to use. Reliable results during inter proficiency trails. Saves time in the laboratory."

"Easy to manipulate, simple software, small amount of titration chemicals, automatic titration."

"It's easy to use and reliable. User friendly. Simple and self-explanatory program operation. Stable and robust.Small footprint, easy software to learn and use. Support and training by Metrohm is great! Excellent apparatus with high-accuracy, robust results. The software and security levels are meeting the 21 CFR. Tiamo software is very user-friendly and fully compliant. The equipment works very well, it is robust and the analyses we carry out (especially acid-base potentiometries) are carried out without problems in a fairly repetitive way."

"Useful, we reach our accuracy targets with ease."

"It's easy to use and reliable."

"User friendly. Simple and self-explanatory program operation. Stable and robust"

"The equipment works very well, it is robust and the analyses we carry out (especially acid-base potentiometries) are carried out without problems in a fairly repetitive way. Its weak point is in the cards that control the DOSINOS, (the MSB ports), if you make hot connections / disconnections from the DOSINOS the MSB ports board is damaged. Taking care to do these operations with the equipment turned off, there is no problem with this equipment. I am very happy with it."

"I achieve high quality results with this instrument, it is easy to use and there have been no problems for many years."

"Easy to use. High precision."

"It's a good and accurate system. It gives good results on time, and it is user friendly so anyone can use it."

"Small footprint, easy software to learn and use. Support and training by Metrohm is great!"

"Great results. No issues with instruments and good support from service engineers."

"Service is good although the price is much higher than we expected."

"Easy to use for method creation/modification and data export/manipulation. Easy to approach for asking for help in application. PM service cost is too high; we schedule it once every 2-3 years."

"Good quality, easy to use. Easy to control and add chemicals inside."

"Reproducible results with every analysis. The system is rugged enough for the analysis of different types of materials."

"Reproducible results every analysis. The system is rugged enough for the analysis of different types of materials."

"The software with its specialized data system is flexible but has its drawbacks., especially if you just need a running system. In itself it is a robust and sturdy tool. But be careful if you pull the wrong plug (simple communication cable), when the system is switched on because it fries the mainboard."

"Excellent apparatus with high-accuracy, robust results. The software and security levels are meeting the 21 CFR."

"It is easy to use and the results are reliable and repeatable. There is excellent technical support from company."

"It is worthwhile for analysis. It giving results we can be confident in. Software is friendly to use. easily accessible to all."

"Produces accurate and repeatable results. Durable consumables and equipment. Value for money. Titrando connected to Tiamo software is more convenient, with the in-built method set in which is very user friendly. Metrohm service engineers are also very helpful, easy to approach them for any help."

"Metrohm equipment, in my opinion, is top quality and value for money. Local support is knowledgeable and swift to attend to breakdowns. I also think Metrohm products are innovative and intelligent."

"905 Titrando is absolutely an asset to our lab as we analyze a lot of different types of samples using this analyzer. This instrument is highly user friendly including the controlling software. Metrohm Chennai is supporting us well from the service side."

"The Metrohm model 905 titrator gives accurate and reproducible results day in and day out. It does have several weaknesses though. The Touch Control unit has been plagued with all sorts of problems. The instrument routinely locks up and must be unplugged to recover from the error. Multiple firmware updates and parts swapping has not resolved the issue. Service support is weak unless under warranty. Data chips used in the dosing units fail periodically causing the titrant to not be recognized. All of these errors are also present on my Metrohm 907 model, also equipped with Touch Control.""

"This product is very effective and precise for sample testing in a QC Lab. Service also excellent. We are achieving high quality/ reproducible results through this product, it is very user friendly. My rating is 5 out of 5 for ease of use, after-sales care and value for money!"

"Product is very good and easy for all four types of titration. Multiple dosing unit can be added for different volumetric solutions. An ion-selective electrode can also be used. Compliant with GMP/GLP and FDA regulations such as 21 CFR Part 11. Tiamo software is very user-friendly and fully compliant."

"It has excellent reproducibility between analyses, perfectly meets our need. We obtained a significant improvement by migrating our method to the equipment, low maintenance costs and spare parts."

"The equipment does not comply with all data ingrity elements, so it should be replaced soon. The equipment touch screen is not so sensitive."

"Customer service on-site is good. system is very difficult to train new users on. We have multiple chemistries and multiple dosing units. On-board connections are bad on the back of the main unit. I would look elsewhere for next purchase Manufacturer Response: Dear Mr. Hovanec, We very much appreciate your honest feedback and will be reaching out to you to see what we can do to improve how you feel about Metrohm. Please accept our sincere apology for the inconvenience you’ve experienced. Kind regards, Dr. Christian Haider Manager Competence Center Titration Metrohm International Headquarters"

"This has excellent software. It is extremely robust, consistent and reliable. It is easily upgradable too. We purchased the Karl Fisher version as well, and two units work seamlessly on same software from the same computer. "

"It is a nice titrator and a very nice solution to the Dosino burette for liquid handling. It has 4-port valve and can rinse and purge burette."
