ATMI has expanded its line of Newsafe contained Powder Transfer Bags with the introduction of bags fabricated with a new anti-static polymer film that increases the number of bioprocessing applications through its significantly extended shelf-life.
The new powder transfer system is fabricated with Permanently Static Dissipative (PSD) film, a patent-pending material, which allows the delivery of powders to any single-use or reusable processing vessel fitted with an industry-standard triclamp interface. As claimed, Newsafe contained Powder Transfer Bags made with PSD film exhibit anti-static properties that improve powder recovery and prevent buildup of electrostatic charge, resulting in significant process efficiency and safety benefits. The system has a shelf life of 36 months.
The PSD film technology was developed by ATMI LifeSciences. Using animal derived component free (ADCF) materials and compliant with US and European pharmacopoeia standards, the PSD film is extruded in-house by ATMI in HEPA-filtered air under cleanroom conditions. Newsafe PSD bags are manufactured in an ISO Class 5 environment to ensure cleanliness that meets or exceeds the most demanding powder transfer and storage requirements.
Richard Bhella, global product manager for single-use storage & delivery technologies at ATMI LifeSciences, said: “Companies can capitalize on this unique combination of benefits in a greater number of instances. The shelf life increases the container’s usefulness for long-term storage or shipping. Customers can even purchase and store powders that are delivered in pre-measured amounts, which facilitates quick, clean, and less expensive addition of critical powders to their processes.”
Newsafe PSD products are said to improve process efficiency by lowering the number of cleaning and validation steps, reducing process downtime, and eliminating potential sources of cross-contamination between batches.
