PenJet is the result of a 10-year development project, according to Tom Castellano, CEO with The PenJet Companies. “It’s made of seven components, with the main housing being an injection-molded, medical-grade polycarbonate piece.” PenJet uses DSM Thermoplastic Elastomers' Sarlink®, a rubber-like material, for a plunger piston and for the peel-off protective cover at the delivery end of the device. The plunger piston pushes the active ingredient, which can include a liquid or a powder with diluent, through the bore of the ampule that contacts the patient.
