Improved emptying
Bottleneck geometry supports more complete discharge of transferred components.
castus® CSU beta bags are engineered for secure, contamination-controlled transfer of components into and out of pharmaceutical isolators — combining single-use efficiency with process-ready performance.
The castus® Single Use (CSU) is a purpose-built single-use transfer system for the safe loading and unloading of sensitive pharmaceutical components. Developed for isolator applications, it combines robust material performance, contamination-controlled handling and practical single-use efficiency in one streamlined solution.
Not just an alternative — a redesigned standard for sterile RTP.
Design details focus on reliable emptying, secure sealing, traceability and practical handling in contamination-controlled workflows.
Bottleneck geometry supports more complete discharge of transferred components.
Welded flange construction is designed to support robust sealing performance.
Injected seal design supports contamination-controlled handling during transfer.
Optional RFID integration can support identification and lifecycle traceability requirements.
Higher effective fill volume provides greater flexibility for process-specific loads.
Reduce cleaning and handling complexity with a process-ready disposable transfer solution.
CSU can be configured to support application-specific handling, docking and transfer requirements.
Customizable from 5 L to 80 L — designed around your process.
Transfer stoppers, caps and other sensitive components into controlled environments.
Support contamination-controlled loading of materials into aseptic processing equipment.
Enable contained transfer of components or materials out of the process environment.
Adapt transfer configuration to process, load, sterilization and handling requirements.
Depending on the selected bag material, castus® CSU supports common sterilization workflows and is manufactured under controlled conditions for pharmaceutical applications.
