Milli-Q^® IQ 7000 Ultrapure Water Purification System by Merck

"We no longer have to purchase ICP-MS grade water for aqueous testing and have been able to bottle our own HPLC water in-house."

"Due to the exact measurements of the distilled water dispenser, our lab results are more accurate now more than ever. Being able to log in which lab takes how much water cuts down on the documentation time that we used to do. The machine is simple to run and easy to use for many different people in our department."

"Merck have produced an easy-to-use DI water system with intuitive user interface. There are several time-saving features to assist productivity in the laboratory, such as automatic and assisted dispense modes, and dispense reporting. One of the standout aspects of the IQ-7000 system is its unparalleled performance. We have seen that water quality has been incredibly important as we industrialize testing in order to develop our product. We receive clear and instructive alerts / warnings when water quality is jeopardized. Consumables are automatically recognized on installation, and the system provides clear instructions for maintenance and upkeep, meaning any laboratory staff can easily manage the system and return to doing what they do best. Price is high, but sometimes you get what you pay for."

"This thing is so easy to use. It's very intuitive. I love how simple it is but at the same time how I have a lot of control over the system. The magnetic arm is a nice touch from the previous model. The displays are bright and responsive."

"Excellent product! My lab has 7 and we will be buying more soon."

"Great product. Waiting for an upgrade. Sales rep was very informative."

"Works great. Now we don't have to purchase 4L bottles of water!"

"Affordable and great to use when making mobile phase."

"Very affordable!"

"It is a great and reliable machine and I use it mainly to make buffers for ELISA. No major issue. It does take a while to generate 5 litres of clean water but again it does the job fine."

"Reliable water purification system with an intuitive interface. We find the IQ 7000 accurately dispenses water in our media preparation facility and the ability to see the dispense history is very useful. It also has a fairly small footprint compared to alternative systems. The consumables are simple to replace and automatically detected by the unit. The system has worked perfectly since it was installed, no complaints!"

"Pleased to say, this system meets our requirements from feedback from our end users (lab staff)."

"This product is so easy to use, I love all of the features that it has. The field service technician that installed it was fast, professional, friendly, and caring. I will recommend this product to other researchers."

"The Milli-Q ultrapure water system in our laboratory is highly versatile and efficient in the process. The ultrapure water is of high purity and also free from microbes. The service department from MilliporeSigma is highly experienced and maintenance is excellent. The instrument is long lasting and can is wonderful for our laboratory routine operations."

"We have had lots of construction in our new building, which has affected the amount of use we are getting out of this product. We cannot wait to use it more!"

"We purchased two of these Milli-Q IQ 7000 Ultrapure Water systems for two of our analytical chemistry labs and everyone using them has been quite pleased with their ease of operation and with the high purity water they produce. I like the many modes of operation these units provide, like being able to deliver a specific volume of water, so you don't have to stand there when filling large containers. I also like the drop by drop feature when you need to fill a volumetric container or the simple ease of use of the manual mode which is the way most people use this system with a simple push of a button to start and stop the water flow. We took advantage of the ability to place one of our Milli-Q systems inside a cabinet under our bench and only place the dispensing unit on the bench top to save valuable bench space, while the other unit was placed directly on top of the bench next to the sink. We would recommend these water systems without hesitation."

"Mili-Q IQ 7000 water system is the most advanced one I have ever used. With the advantage of presetting the volume, no water overflow occurs anymore. With adjustable flow rate, the desired small volume can be easily achieved. The height of the remote dispenser holder is adjustable as well. It is convenient not to remove the dispenser from the holder since it can fit various heights of containers. However, I experienced an issue , which the company is currently working to resolve."

"The Milli-Q IQ 7000 filter system is esay to use, the dispenser is very helpful to preset water volume. As long as the water volume is over 200 ml it is very accurate. Highly recommend."

"The ability to dispense a specific amount of water is a GREAT improvement. Eliminates the need to use a separate trace metal clean graduated cylinder for measuring and saves the lab from flooding when an unattended carboy is forgotten about! I also like having the controls/electronics above the counter so they do not need to be covered from splashes (and are easier to see)."

"Very easy to use. Convenient. The measured volumes may be a bit off but they're close."

"Product achieves required quantity of ultra pure water. Unfortunately the Milli-Q IQ7000 constantly goes into error mode. We were told nothing can be done and that the water quality meets spec. Hard to explain to regulatory bodies that perform lab inspections. I would not consider purchasing this unit again. Support/product knowledge needs improvement."

"I haven't used the system much so far, so I haven't needed to replace the UV light yet. This will likely be the most expensive maintenance work that I will have to do on this instrument, but I was told this before purchasing it by the sales representative. I like how easily the computer gives you instruction on when the machine needs something to be replaced. Great buy so far!"

"Easy to use. Easy to maintain. High quality purified water."

"The filters are well made, they last a solid 6 months, which is very important for process. I am very pleased with this unit QI-7000. We are very pleased with Millipore and this unit is fantastic."

"This is an edit of my previous review. After initial problems, Millipore replaced the unit (twice) and now it is working as intended. Sales rep. (Rob) and the new field engineer (John) are great!

Reviewer's original comment:
Water purifier purifies water, that's good new interface is nice, although probably unnecessary. Long wait for installation, first installation defective, slow service, first field engineer had no idea what he was doing, needed second visit, second field engineer was OK. If there was a competing product would probably buy that instead, lack of competition is sad."

"Ultra pura water. Very minimal contaminants compared to other branded ultra pure water. Very easy to use and convenient compared to bottled water."

"Consistently achieves < 3 ppb TOC and < 18.2 MOhm resistivity, resulting in low backgrounds in both organic and inorganic analysis."

"Fast Installation, Came up quickly, Great Dispensor (all your data at head height vs instrument front). Love small footprint of dispenser and cleanup unit tucked in the back of the bench."

"Very easy to use, very good after sale assistance and service."

"Excellent product. Very easy to use and very good quality."

"It is a very good instrument and gives high-quality results. Initially, it was somewhat difficult to use but now it is very easy to use it. I would recommend it to others."

"The product is easy to use. Stewart was my sales rep. He is helpful and replies pretty quickly. He came and checked up on me a couple times so that is nice. I called tech support once and they were also helpful. Unit looks sleek and has a decent sized footprint. I recommend this product."

"The Milli-Q IQ 7000 water system is highly user friendly and produces ultrapure water that is compatible with applications in our lab. The graphical interface consistently provides the user with up-to-date information about the status of the system, and whether cartridges or filters need to be exchanged. The Milli-Q IQ 7000 is a must have for those who want high quality water from a water purification system with minimal down time for maintenance or repairs."

"Great value in the product. Extremely easy to use and have had it for over 3-months without one complaint"

"This product is a must gave for every lab. The quality of water is very consistent, which reduces time spent optimizing buffers (especially calcium concentration). It is also easy to use and occupies little space."

"Does a great job of delivering 18 mohm DIH2O. I use the added VOC pack to ensure the water is VOC free. Unit is very easy to use. I love the touch screen feature and the ability to dispense volumetrically (no more overflowing/wasted water if you walk away for a moment or forget). Would recommend to anyone needing DIH2O for their lab."

"Ease of use: nice interface After sales care: Installer was knowledgeable and very helpful with the training Value: Price was better than the previous model."

"This is a very nice water deionizer. It is easy to use with little training. The water quality is excellent. The automatic fill to volume feature works well and prevents water spills in the lab. It is compact so takes up very little room on the Lab Bench."

"High quality water and very easy to use. It's been totally trouble free."

"This water system is amazing and I'm a tough sell. The control panel is very intuitive which is great for labs who have students working in them. Everything you need is right at your finger tips and the system virtually maintenance free. I work in a communal lab and I'm very very happy that I chose this milli q water system for everyone and have received praise for my choice."

"The Milli-Q IQ7000 system works is very easy to use. The quality of the dispensed water has been good and the system has exceeded our expectations to this point. The sales team and installation team were also top notch."

"Works great. very easy to use. setup and install was smooth with great support."

"This system is absolutely amazing. The ease of use is great, the filter exchange is so easy and the after sales care we get is phenomenal."

"Great user-friendly touch pad included on the dispenser pod. The optionnal polishers help us having the best quality water without any particles for our SEC-MALS applications."
