Middlesex Gases

Middlesex Gases is a third-generation, family-owned supplier of specialty gases, regulation equipment, and bulk and MicroBulk gas systems headquartered in Everett, Massachusetts. Founded in 1949 by Joseph Martin as Middlesex Welding Supply at 1655 Revere Beach Parkway, the company has grown into one of New England's leading independent gas distributors, with an extensive distribution network covering Massachusetts, New Hampshire, Rhode Island and Connecticut. It serves customers ranging from start-ups to Fortune 100 companies, with particular strength in biotechnology, life sciences, universities, medical research laboratories and industrial welding. The company operates three gas filling and testing facilities in Everett, Lowell and Plainville, Massachusetts. Its state-of-the-art specialty gas laboratory in Everett is capable of automatic and gravimetric filling of both nonflammable and flammable gas mixtures, and the company has invested over one million dollars in the plant to guarantee precise and accurate results. Middlesex Gases supplies high purity, ultra high purity and research grade gases as well as more than 50 custom blends, with specialty gases rated at 99.999% purity. It also offers bulk and MicroBulk systems for customers using 1,000 liters of gas per month or more, liquid dewars for nitrogen, CO2, argon, helium and oxygen, and regulation equipment. In recent years Middlesex Gases has expanded into dry ice manufacturing. It produces dry ice in-house at its Plainville facility and delivers it fresh off the production line to medical, pharmaceutical, biotechnology, life sciences, industrial and welding customers across New England. The company is one of just three gas companies in all of New England that both manufactures and distributes dry ice, producing up to 10,400 pounds per hour. Dry ice is offered in rice pellets, MicroPellets, quarter-inch pellets and three-quarter-inch pellets, with insulated 200-pound and 500-pound containers, barcoded tracking, and fully enclosed delivery trucks. Middlesex Gases positions itself as "The Elite Gas Supplier for New England," emphasizing dependable service, quality products and customized gas solutions. Its fleet of box trucks and trailers, combined with its three filling stations, provides the service advantage it markets to customers. The company remains privately held and family owned, with a history spanning more than 70 years in the gas supply industry.

Middlesex Gases was founded in 1949 by Joseph Martin as Middlesex Welding Supply, located at 1655 Revere Beach Parkway. Martin's vision was to create and operate a strong, independent distributorship that would sell quality products at a fair price and back them up with excellent service. That philosophy helped the company become an industry leader in the New England gas supply market. Over the decades, Middlesex Gases expanded its capabilities and geographic reach. The company grew from a welding supply distributor into a full-service specialty gas supplier, adding high purity, ultra high purity and research grade gases, custom gas blends, bulk and MicroBulk systems, liquid dewars and regulation equipment. It established three gas filling and testing facilities in Everett, Lowell and Plainville, Massachusetts, and built a state-of-the-art specialty gas laboratory in Everett capable of automatic and gravimetric filling of both nonflammable and flammable gas mixtures. The company invested over one million dollars in the plant to ensure precise and accurate results. By the 2010s and 2020s, Middlesex Gases had become a third-generation, family-owned business with more than 70 years in the gas supply industry. It serves customers from start-ups to Fortune 100 companies, with a focus on biotechnology, life science, universities, medical research laboratories and industrial welding. Its distribution network covers Massachusetts, New Hampshire, Rhode Island and Connecticut. In 2020, Middlesex Gases expanded into dry ice manufacturing, producing dry ice in-house at its Plainville facility. It became one of just three gas companies in all of New England that both manufactures and distributes dry ice, with production capacity of up to 10,400 pounds per hour. The company offers dry ice in rice pellets, MicroPellets, quarter-inch pellets and three-quarter-inch pellets, with insulated 200-pound and 500-pound containers, barcoded tracking and fully enclosed delivery trucks. This move further solidified its position as a comprehensive gas and dry ice supplier for the New England region.
