What Gloveboxes Group does

E3i Group is a privately held industrial manufacturer of controlled-atmosphere and containment equipment, organized as the parent of three specialist subsidiaries: Jacomex SAS (France) for gloveboxes, containment enclosures, and isolators serving nuclear, research, chemicals, and battery industries; Inert Corp (USA, headquartered in Amesbury, Massachusetts) for gas purification systems and inert atmosphere solutions; and EREA Pharma / EREA SAS (France, Peronne) for aseptic and cytotoxic isolators used in pharmaceutical production of injectables, creams, and powders. Founded in 1945 and operating for approximately 80 years, the group delivers turnkey and tailor-made engineered solutions rather than standardized catalog products, with design and manufacturing carried out in-house across French and US sites in Dagneux, Peronne, and Amesbury.

The product portfolio centers on four core technology families: sealed gloveboxes with integrated gloves for material manipulation in inert atmospheres; gas purification systems that remove moisture, oxygen, and other contaminants to sub-ppm levels; pharmaceutical-grade isolators for aseptic filling, sterility testing, and cytotoxic drug handling; and specialized nuclear glove boxes providing radiation shielding and radioactive material containment. Differentiators cited include deep domain specialization across regulated verticals, proprietary engineering mastery within each subsidiary, and the ability to engineer bespoke configurations for demanding customer specifications.

The business model is B2B project-based custom equipment sales combined with aftermarket services, monetized through direct enterprise sales engagements in regulated industries. Pricing is quote-based and not publicly disclosed. End markets served include laboratories and R&D, battery and energy, pharmaceutical and medical, general industrial, nuclear, and additive manufacturing, with named enterprise and government customers spanning NASA, Sanofi, GSK, Merck, Framatome, Naval Group, TerraPower, Entegris, Collins Aerospace, Total Energies, MIT, Harvard, and CNRS.

• Inert Corp
• EREA Pharma

Products and services

• Gloveboxes Sealed containment enclosures fitted with integrated gloves that allow operators to manipulate sensitive, reactive, hazardous, or radioactive materials inside a controlled, contaminant-free atmosphere. Used across nuclear, research, chemicals, battery, aerospace, and advanced industrial applications where environmental isolation of materials is required.
• Gas Purification Systems Systems that continuously purify the atmosphere inside gloveboxes and enclosures by removing moisture, oxygen, and other contaminants to maintain low-ppm or sub-ppm inert atmosphere conditions. Sold to laboratories, universities, R&D centers, and battery/advanced materials facilities requiring stable, high-purity atmospheres.
• Isolators Advanced containment enclosures (both flexible and rigid configurations) that provide sterile, aseptic, or cytotoxic isolation environments, protecting the operator and the surrounding environment from hazardous or sterile-process materials. Used in pharmaceutical filling, sterility testing, formulation, weighing, and cytotoxic drug handling.
• Nuclear Glove Boxes Specialized containment equipment that provides radiation shielding and safe manipulation of radioactive materials, delivering total protection for both operators and the environment against hazardous nuclear materials and ionizing radiation. Used by nuclear operators, research reactors, defense programs, and advanced nuclear reactor developers.
• Aseptic and Cytotoxic Isolators Pharmaceutical-grade isolators designed for aseptic processing and for safe handling of cytotoxic compounds during the production of injectables, creams, and powders, including aseptic filling, sterility testing, and formulation. Deployed at pharmaceutical manufacturers and targeted at compliance with pharmaceutical regulatory regimes.
