Blow Molded Reagent Bottles for the Medical Device Industry

At R&D Molders, Inc., we are adept at accommodating specialized manufacturing requirements like those detailed in the custom molding project highlighted here. The product shown is a 2 liter medical reagent bottle that is blow molded out of HDPE resin. The bottles are molded using multiple cavity output continuous extrusion blow molding equipment and are treated with a post mold fluorination process. During the fluorination process, components are exposed to fluorine gas in a sealed reactor. The fluorine gas creates a permanent bond with the plastic material, making the component less susceptible to permeation, discoloration, odor emission, and paneling. Post mold fluorination is the only FDA approved fluorination process and is used in a variety of medical and pharmaceutical applications.

After processing, the bottles are labeled, double bagged, and placed in lined cartons before they are shipped to the customer. These precautions must be taken because the bottles are used immediately in a clean room filling application upon arrival at the customer’s facility. During the development process, an inline "poka-yoke," or mistake proofing, procedure was put in place to remedy initial processing issues that caused the bottles to bulge during production. The bottles were manufactured to tolerances as tight as ±0.005" and include a "kiss-off" feature in the design to provide added strength in the center.
