Amazing customer service from start to finish. They responded to my emails very promptly and even had a service tech come out to our lab within a day. We would definitely do business with them again!

She has the experience, knowledge, and skill level to provide great results to solve your instrumentation, parts, or software needs. GMI is the Gold Standard when it comes to customer service. Gwen brings a positive energy that is evident with every transaction that makes you realize how much she enjoys her role with GMI.

Can't say enough about GMI and their customer support & sales staff. We've done countless transactions with them (new product purchases, selling our old equipment back) and always walk away happy. And their pricing is always sharp! Price and customer service aren't a trade-off here.

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!!!

Needed to purchase a centrifuge rotor for a customer of mine. GMI is a company that I look at first as their inventory is excellent. 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!

We recently ordered the Universal Image Hood from GMI Labs. We found the system to be the cheapest available option for our purpose. The technical staff came down and helped us with the setup. So far, the system has worked very well and we are extremely satisfied with our purchase.

We bought a microplate reader from them- the equipment works great, and the technician they sent out to install it and teach us how to use it was great. My experiment is running very smoothly because of his advice.

GMI had the best prices on a refurbished FPLC and they gave me a fair value for my trade-in. The salesperson and technician were both responsive and helped explain the different FPLC options very clearly. Have purchased from GMI before and will do so again.

Great customer service, knowledgeable staff, AND they gave us a free upgrade on the equipment we purchased. The sales rep had good information about various brands and assured us that GMI has all parts on-hand for whenever something has to be fixed in the future. The 10+ year old centrifuge we purchased looks and runs like new!

I first contacted GMI when I was searching for a used biosafety cabinet. The customer service was amazing. They helped me find the one that best fit my needs at a great price. They maintained communication throughout the entire process--ordering, shipping, and even after it was received. Overall, it was a fantastic experience!

I've interacted with GMI with a couple different pieces of lab equipment and they were straightforward and honest throughout the whole process. From receiving multiple quotes to accommodate uncertain funding constraints to a complete Depot/Maintenance service, GMI was quick, courteous, and professional. I plan to be a repeat customer!

From day one, I was impressed with GMI's energetic sales team and competent technical staff. They put forth the effort to understand our equipment needs, brand preferences, and budget constraints. Their commitment to service extended far beyond simply providing our lab equipment; we wanted a 'drop-in' solution to minimize laboratory down-time. GMI met our exacting challenge by coordinating delivery, placing equipment on the lab floor, and performing installation on the day that was specified. It was an impressive feat ... $200,000 of gear, two trucks, six movers, one service engineer all in-and-out within a day. The equipment arrived in great condition, was placed exactly where we wanted it, and was installed and verified for use. When we embarked on building a new lab, we were looking for a vendor, but also for a partner. We found one in GMI.
