OPL‑Series Extended‑Length Medical Pouch Sealer
The OPL‑Series is engineered for precision, repeatability, and long‑term reliability in regulated medical device packaging environments. Its powerful direct‑drive electronic solenoid delivers consistent seal‑to‑seal force, ensuring highly repeatable sealing performance. A thin‑film thermocouple continuously monitors thermal conditions at the sealing interface, enabling fine‑tuned temperature control for optimal seal quality.
Designed with longevity in mind, the OPL‑Series is gentle on consumable components, helping maintain a low cost of ownership. A simple, intuitive step‑menu guides operators through setup and pouch changeovers, supporting fast, efficient workflows. Every unit ships from our ISO 17025–accredited calibration laboratory, providing accurate, traceable calibration for ISO 13485 medical device manufacturers. For more than 32 years, Van der Stähl Scientific sealers have produced billions of sterile barrier seals for users around the world.
Airless Operation
The OPL‑Series uses a robust solenoid‑actuated sealing bar controlled by an advanced microprocessor to generate precise sealing force—without the need for compressed air. Eliminating air systems removes the complexity of air‑source validation. Simply plug the unit into a standard power outlet and begin packaging.
Built for Durability
Many OPL‑Series sealers have been in continuous service for more than three decades. Constructed with heavy‑duty frames and precision components, these machines are built for demanding production environments. With more than a billion seals produced annually across our global user base, the OPL‑Series continues to be a trusted choice for medical device manufacturers.
Accurate, Accredited Calibration
Each sealer is delivered from our fully accredited ISO 17025 calibration laboratory. We perform multi‑zone internal temperature calibrations for improved accuracy and traceability. Our optional Pro Calibration expands this process to include time verification and multi‑zone force calibration of the mechanical system.
OPL‑Series Pouch Sealer Options
Available in three sealing lengths—300 mm, 450 mm, and 600 mm—the OPL‑Series accommodates a wide range of medical pouches, including large‑format packaging. Custom configurations with upper and lower heating elements are available for sealing heavy gusseted pouches. The system supports a broad spectrum of materials such as Tyvek®, foil, nylon, poly, and Mylar, and includes ISO 17025–accredited calibration with every unit.
Extended‑Length Medical Device Packaging
The OPL‑Series produces a robust 10 mm‑wide seal and can accommodate pouches up to approximately 23 inches wide. Its powerful solenoid eliminates the need for compressed air, while the onboard microprocessor allows precise adjustment of temperature, contact time, and release temperature. Operators can choose semi‑automatic touch‑free operation or activate the sealer via footswitch or table switch for added flexibility.
