Our laboratory at the University of Chicago has used DAI Scientific for over 15 years to help us establish and maintain a Freezer Farm. We could not recommend DAI more highly for consistent service and reliability. They provided any lab equipment we requested, and delivered competitive pricing and outstanding customer service.
University of Chicago
The Department of Pharmaceutical Sciences at Wayne State University has had a close and highly productive relationship with DAI Scientific for over two decades. DAI has provided a level and quality of support and commitment that is not seen in other suppliers/providers, whether for our range of freezers needs or for the diverse requirements of new faculty as they provision their labs. DAI has offered us the most competitive pricing in the marketplace. Their personal hands-on approach is second to none. Congratulations to a premiere organization with a very bright future.
Wayne State University
Our company has grown significantly over the last ten years. One thing I know I can always count on is DAI and their rep, Brian Langenderfer, doing their part to keep us informed of specials on instrumentation, get us great pricing on quality inventory, and rapid response times on all communications, including quotes. Not only that, but they coordinate quality movers to come onsite upon delivery and help unpack, move, and set up equipment professionally. What I also appreciate as a lab manager is having the DAI employees, like Brian, to support all installations, upkeep, and is available for general questions. As our one lab has now grown to four, I always make sure my lab operation peers use DAI as their first “go to” for equipment purchases. We are always impressed and never disappointed with our DAI experiences.
