Optimal adaptability for your freeze-drying process
Are you searching for a simple solution for your individual freeze-drying situation?
What can be easier than using the open containers of your choice and safely enclosing them with our Lyoprotect® Bags for Bulk? The high-performance membrane ensures safe lyophilization without compromising the performance of the cycle. Opt for a multiple-use closing system or choose a heat-sealing strip for flexible closure.
Features of the Lyoprotect® Bags for Bulk
Versatile application
Simply place a single-use or a multiple-use container inside the Bag for Bulk to keep fly-out inside and protect your contents. After closing the bag, it can safely be moved to the freeze dryer.
Safe sublimation
The Lyoprotect® Membrane on the upper side of the bag acts as a sterile barrier and ensures zero fly-out. Vapor effortlessly passes through the hydrophobic membrane, which supports fast drying.
Customized sizes
The bags are manufactured in individual dimensions for optimized footprint utilization of the freeze dryer shelves. They can even come with a filler assembly to facilitate your processes.
High quality
Our bags are manufactured in Germany, with 100% visual inspection of the individual components and final bags. Extraction study plus toxicological assessment and validation guide available.
Sterilization
All components are suited for sterilization in an autoclave at 121°C (250°F) for 20 minutes. Sterilization validation available on request. APIs can be aseptically produced in compliance with GMP.
Closure of choice
Safely close the bag with our multiple-use closing stick. For a more flexible solution, or if space is an issue, the bags are also available with a heat-sealing strip on one side (to be joined with a heat sealer).
