I bought a couple laboratory scales from GMI and was not disappointed with the whole experience. The sales staff replied my initial inquiry with a few suggestions and some pointed questions pinpointed a specific model to suit my application and promptly provided a very competitive quote. Ordering was super easy and I was kept updated on the order status (receipt, warehouse testing and calibration, ship date). Shipping staff cares about the product arriving in good condition and the scales were packaged incredibly well.I can't say anything against GMI and will certainly have them quote on my future laboratory needs.

Daniel Fines

GMI really lives up to its name of being "Trusted", for sure! We purchased a refurbished plate reader that had some technical issues. The turnaround time to get it fixed was truly impressive (3-4 days). GMI has a core team of experienced and very knowledgeable service engineers who work to provide an efficient and speedy resolution! These would be top reasons for any lab looking to buy quality, certified instruments to go with GMI.

These guys have great customer service! They also deliver a great product. We got two laminar flow hoods from them and both are pretty great.

Leonard Marovelli

GMI was an incredible company to work with! When our hoods failed inspection, we reached out to GMI and they worked extremely quickly and productively to get us new hoods delivered as soon as possible. We are completely thrilled with how quick and easy it was for us to get back to our experiments in the hoods. Caleb was a great representative and understood our stress and urgency. GMI overall was incredibly responsive and customer service-oriented.

Allison Maebius

We used GMI to order equipment for a new compounding pharmacy. I had the pleasure of working with Travis H. and could not be happier.

They had what I was looking for and were able to be competitive with other vendors. All in all, I received the rotor promptly and packed securely. All the people I talked with during this process were helpful and friendly. A combination that can't be beat. The unexpected gift was a nice surprise!

GMI is a great source for used and refurbished lab equipment. GMI takes a lot of pride in their work and it feels more like the security of buying new equipment rather than used. Their service people are nice and easy to work with and Jason B. is a friendly, responsive sales person.We bought an old Beckman floor model centrifuge earlier this year and it's been running wonderfully. When the motor drive belt broke, they had a new belt to us in a couple of days. Easy peasy.

I worked with Gwen to sell a couple old pieces of equipment which were just taking up space and collecting dust in our lab. It was super easy to send her pictures, agree on a price, pack up the items and ship them back to GMI with a prepaid shipping label! I strongly recommend this as an option to cleaning out old equipment. It's much better than just scrapping it!!!

Our laboratory's micro-centrifuge finally quit working, so the time had come to find a replacement. We had opted to upgrade to a bench-top one to have some redundancy with the Beckman GPR we are currently using. At first we had checked with a large well-known distributor of laboratory supplies/equipment, but their customer service wasn't up to par and pricing on a new unit was very high. At that point we decided to look into refurbished equipment. The sales reps at GMI were excellent! They helped us explore all of our options for our new (used) equipment, were extremely informative, and had great communication. In the end, we ended up with a great centrifuge at less than a quarter of the cost of a new one and it shares accessories with our older Beckman unit. Couldn't have asked for a better experience. On a side note, I noticed that our gamma counter was also purchased at GMI and has been running strong for the past 11+ years. Thanks everyone at GMI!

Getting grant funding is hard! Bio-medical / Chemistry / Biochemistry equipment is really expensive and it eventually breaks down (usually before the graduate students, too). GMI has always had great prices on the equipment I need to run my lab and more importantly they have always stood behind their equipment. Any and all issues have always been resolved timely and fairly. Even when something does break (like an HPLC) just past it's warranty; they also provide great repair services and again at fair cost (typically more cost effective than the dealer / manufacter). GMI has even offered extended warranties so you can be sure you'll equipment will last the length of your grant. There are other places where you can get equipment (or gamble on eBay) but GMI has always delivered for me and therefore I highly recommend you contact them for your equipment needs. You won't be disappointed because if something is amiss just let them know--they will resolve it. Happy shopping!

GMI sold me a new biosafety cabinet for my laboratory I was setting up. It is exactly what I needed, and the GMI representative spent a great deal of time with me on the phone describing the product and comparing it to other products. The reps knowledge level seemed much higher than many of the other company reps as well. The product is working great. One thing that could make the process better was the installation instructions for the biosafety cabinet were pretty poor... but that probably has more to do with the manufacturer of the biosafety cabinet and less about GMI. I will definitely ask GMI in the future for quotes on instruments or equipment I will need for my lab.

O'Reilly Matthew

I love working with GMI! My interactions with various representatives are always pleasant. They work with you based on your criteria/budget and actually follow-up with you to ensure satisfaction. I've worked with a large variety of companies, and I can honestly say that no one compares to GMI.

GMI provided us with a refurbished model of an old-school electrophoresis machine that we need for lab analysis. Once it came in, it worked like a charm and has provided us with highly beneficial data like a dream. Glad we could get one, as they no longer make them and thank you GMI for being great to work with.

We needed a biosafety cabinet when ours stopped working and Jason from GMI was able to find us a great brand new Thermo hood within minuets! The whole process was pretty quick and painless, from getting the quote to having the hood, it was about two weeks.

My lab has been a customer of GMI for several years. When we opened up the blood Diagnositics Lab we looked to GMI to get a Hematology Analyzer. Working with GMI has been very good. Every instrument has its on issues and GMI’s customer service has been higher than what I expected. Each person I had to deal with has been exceptional in helping me resolve any issue I had. Used instruments often have some issues and Rick in the service department has been extremely easy to work with and helping me resolve those rare issues.Thank you GMI for making my experience very beneficial for the patients I serve!!John Andrews, Manger Blood Diagnositics LaboratoryAEON Global Health

We have made two big purchases with GMI, including multiple new instruments and used ones too. Their price is very decent, some items are even lower than that of Amazon. Their service is also top quality. When the HPLC computer goes wrong during the initial set up, they replaced the computer right away. We also get a lot of help during the set up the autoclave. They stick to their conditions of the sale, when there is something not same as the original description, they made a very large discount to our second big purchase for compensation. In all, they did their job excellently.

As the owner of an analytical laboratory, we are constantly updating or replacing our instruments. GMI is always my first stop when I start to shop. I've purchased both refurbished instruments as well as new instruments and all works as promised. If I have any questions from the technical team, they have always been available and helpful. I've saved thousands of dollars by buying through GMI. Great company with good products and excellent customer service.

It was a pleasure working with GMI regarding the acquisition of a Knauer 80 P HPLC Pump. GMI replied to e-mails and inquiries promptly and the submitting payment was easy. Delivery times were fast as well. I would definitely look to GMI again for future needs.

I bought equipment from GMI. The equipment worked as promised and they were good about helping set it up and getting it working. Their tech service was available by phone. But I only needed it to help set up-the equipment worked well and did everything we needed.Now that I'm closing my lab, I've called a number of used equipment companies about buying my equipment, and GMI has been the best and most receptive.. They've been good to work with on either end of the transaction. And they're nice people on top of their competence!If I need to buy equipment again, they'll be my first call. I'll get a good price, a reliable piece of equipment and technical support after the sale.

I had a great experience buying a PCR machine from Kosta Moore at GMI. Kosta was always professional and helpful and even took the time to deliver the PCR machine right to my lab and set it up for me. I highly recommend working with Kosta Moore from GMI.
