General Lab Use

Joseph Crusco helped us figure out the product installation issue and he is very professional and helpful! We got good customer service and assistance on what we need for the next steps. We have been using this Flex3 for many years, but Joseph Crusco is the only one who found our installation issue that never has been found during the previous maintenance.

Elga DI with Veolia service is a great combo


Average Rating 5.0

Application Area:

Dispense filtered DI water

We require DI water for so many applications, of course, we want to be confident that our water is never a source of contamination or causing irregularities. Our Elga Purelab Flex 3 does the job well but we may need to scale up to a larger volume capacity soon. Regardless, since we have a service contract with Veolia, I was pleasantly surprised that they reached out to us after the initial PM service in order to schedule our 6 mo follow-up. Normally this is something I would need to put on my calendar to remind myself to schedule it, but Kunal from Veolia initiated the service visit seemingly out of the blue (but right on time!) saving me a lot of regret and time. He was quick and great to work with, and very gracious to me even though I caused some minor service delays. I hope to work with him again in the future!
