ILMO Medical Gases’ customers range from hospitals and nursing homes to medical laboratories, device manufacturers, and universities. Many of our medical customers also rely on ILMO Specialty Gases for rare and critical gas mixtures.
ILMO Specialty Gases’ ISO/IEC 17025:2017 Accredited gas laboratory provides high and ultra-high purity gases throughout ILMO’s current territory as well as to Canada, Central and South America, and Europe through disposable and reusable cylinders. They serve many of our same industrial while also supplying laboratories, universities, high-end processing companies, law enforcement agencies, and medical equipment/device manufacturers. What makes us different?
ILMO Propane, our newest specialty department, started in 2011 and serves many of the same industries as ILMO Products, as well as commercial and residential propane users.
