Microprocessor-controlled rotary sealer with printer for the packaging of sealable pouches and reels (SBS). The validatable hm 850 DC-V rotary sealer is used for the automatic closing of sealable pouches and reels (Sterile Barrier Systems SBS) in hospitals (CSSD) and the medical industry. Our successful classic model hm 850 DC-V was revised in details and adapted to the current design. The sealing process is validatable in accordance with ISO 11607-2 as well as the requirements of the therefrom resulting specifications of the Guideline for the Validation of the Sealing Process. Functionality The hm 850 DC-V rotary sealers have the new, clearly laid out keyboard display. Through this central control unit, all instrument functions and settings are clearly laid out for the user. The hm 850 K PC-keyboard (optional) makes data entry even easier. During the sealing process, the critical parameters sealing temperature and contact pressure are automatically monitored. If one of the parameters deviates from preset values, the device warns the user acoustically and stops the sealing process. The hm 850 DC-V possess a PC interface (RS232) for process and batch documentation. The sealing device guarantees efficient and reproducible packing, especially for large volumes of instruments.
