“Great company to buy from and work with. Alexis has gone above and beyond to accommodate my lab needs, very knowledgeable and resourceful. The product we purchased came in great shape better than expected. But ultimately customer service is what will keep me been a customer for life. Great Job! I highly recommend Conquer Scientific to all my colleagues.”

“I bought a LC/MS/MS and HPLC from him in 2013. Today (in 2021) both machines are working intact. In case you need fixing machine, he can make arrangement. So far I needed only one time maintenance, and he provided much cheaper maintenance. By the way, I am a professor in one of the top university in the US. I buy equipment often from him.”

Pramod P.

“Dr. Fatih and Alexis Gonen supported fairly unrealistic requests in our purchase process. Our research conditions were extremely speedy and they had equipment, and shipped it according to our needs and trained us. We will absolutely reach out to them in the future for further analytical equipment needs.”

Christopher C.

“We bought an Agilent 6890 GC and had a tremendous experience. One part went bad out of the warranty period and they still sent me a new part. We were pleased enough to buy an Agilent HPLC. The small problems I've found with tubing or accessories that one would expect in buying a used piece of equipment are taken care of immediately and the parts arrive quickly. Ask for Alexis. She's the best.”
