Founded in 1977, satisfying customer needs is a matter of personal pride at J.G. Finneran. We communicate with the people who use and distribute our products, and we listen to what they have to say. Based on the information they give us; we respond quickly and effectively to problems and new application requirements with efficient and innovative solutions. Our approach has resulted in a host of new designs and patents over the years, establishing J.G. Finneran as a world leader in glass and plastic product design.

As a recognized industry innovator, we offer a complete line of unique proprietary items designed to save our customers time and money. Coupling over a quarter of a century of experience with in-house glass and plastic production facilities, we manufacture and stock our own proprietary items and a variety of standard glass products. Customer involvement and satisfaction is what we are all about. Our engineering and design team develops new products and provides continual modifications for existing ones. Efficient support personnel monitor each order to assure product quality, timely delivery, proper technical support, and training on product use.

Our manufacturing operations combine the most modern equipment with our own custom designed machinery and accessories. Specialized, highly automated glass and plastic manufacturing machinery handles volume production while maintaining product integrity. Capable of operating automatically seven days a week and twenty-four hours a day, our molding machinery is designed for easy, quick changeover, making both short and long runs cost effective.

From the annealing ovens to the plastic parts separators, our attention to detail at the initial stage of production assures high quality for all our glass and plastic vials, closures, microplates, and inserts. Produced to meet a wide variety of user specifications, Finneran products maintain their consistency from batch to batch.
