Introducing the Stomacher® 3500 Autoclavable Blender Bag


The first paddle blender bag designed to be autoclave resistant for disposal

The new Seward Stomacher® 3500 Autoclavable Bag is the first paddle blender bag designed to also be autoclavable for sterility methods post-testing. This innovative technology aims to:
