Sterile Continuous Bags | Continuous Aseptic Powder Transfer

2026-09-14

Sterile continuous bags enable the continuous, aseptic transfer of powder and other materials out of an isolator, hopper or process vessel without ever breaking the sterile barrier. By sealing and cutting sections of the bag at intervals, material can be removed continuously while the remaining bag stays sterile. Wuxi Harmake Technology Co., Ltd. manufactures sterile continuous bags for pharmaceutical and biopharmaceutical processing. What Is a Sterile Continuous Bag? A sterile continuous bag is a long sleeve of sterile single-use film attached to a process port. As material flows into the bag, the filled section is heat-sealed across the sleeve and cut off for removal, while the next section remains attached and sterile. This allows continuous operation, faster processing and safer handling of potent materials. How Sterile Continuous Bags Work ●The bag sleeve is connected to the isolator or equipment port ●Material fills the bag under aseptic conditions ●A heat sealer creates a seal across the filled section ●The filled section is separated while the sterile barrier is maintained ●The process repeats continuously for high-throughput operation Benefits of Sterile Continuous Bags ●Continuous operation with no...
