The Beckman Optima™ LE-80K Ultracentrifuge offers the fastest separations possible in the minimum amount of time with its performance capability of up to 80,000 rpm. This versatile model is compatible with a wide range of superior rotors and tubes. Capable of rapid run times, the Optima™ LE-80 K is perfect for a broad range of applications.
Featuring a high tolerance of rotor imbalance, this Beckman centrifuge uses a frequency-controlled, air-cooled, direct-drive induction motor that requires no brushes or gears. Operators are assured of smooth and quiet performance with this externally forced-air cooled and internally oil cooled unit.
Equipped with easy-to-use, environment-friendly and microprocessor–based control cooling systems, the Beckman LE-80 K eliminated the use of CFCs and other dangerous liquid refrigerants. This Optima centrifuge is operated through a keypad control panel, and digital display which shows parameters including rotor speed, run time, rotor temperature, w2t value, and selected program number. The display has a dual purpose, indicating both actual values/conditions and set values.
Other features of the Beckman Optima™ LE-80 K centrifuge include automatic standby mode, overspeed and purge system, LED run indicators, and diagnostic messages. Its design includes a high strength structural steel chamber door with a solenoid interlock which prevents it from opening during operation. The LE-80K has an aluminum rotor chamber, coated with a chemical-resistant epoxy finish.

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! 
Tara Naman 15:35 21 Nov 18 Both as a Biomed and as an Independent Contractor I have been utilizingthe assistance of Gwen at GMI. 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. 
SCOTT MANDLER 22:47 24 Nov 18 Great customer service, helpful staff and technical support. GMI provided detailed instructions and fair estimates for the equipment service which we required. Service was performed in a timely and seamless manner. 
Jerry Gene 11:13 08 Nov 18 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. 
Chris P 19:58 14 Nov 18 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!!! 
Cris Brown 12:24 11 Oct 18 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! 
Greg Gadd 21:46 02 Jan 19 We recently ordered the Universal Image Hood from GMI Labs. We found the system to be the cheapest available option for our purpose.

EMGS mutations 21:15 11 Nov 19 I've worked with GMI a few times this year. I've both bought and sold equipment with them and they always make the process transparent, easy, and efficient. I've found that their pricing is highly competitive too. 
Katherine Barcay 21:52 04 Dec 19 GMI has great refurbished instruments that last for years. Their staff is very competent and friendly. I strongly recommend GMI to academics. Very competitive price and great quality. 
Nathalie Wall 16:26 11 Dec 19 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.
