Single-use storage bags are the modern solution for storing media, buffers, intermediates and process liquids in biopharmaceutical manufacturing. By replacing stainless steel tanks, they reduce cleaning burden, lower contamination risk and offer greater operational flexibility. Wuxi Harmake Technology Co., Ltd. manufactures 2D and 3D single-use storage bags for bioprocess and pharmaceutical applications.

 

 

A single-use storage bag is a sterile disposable bag used to hold liquids during storage, transport and processing. It is made from biopharmaceutical film and fitted with ports and tubing for filling and draining. After use the bag is discarded, eliminating the need for cleaning and sterilization between batches.

 

 

 

●2D single-use storage bags - flat design ideal for small and medium volumes

●3D single-use storage bags - three-dimensional design for large volumes with support vessels

●Both designs offer complete closed-system operation

●Selection is based on volume, liquid handling and facility layout

 

 

 

●Eliminates cleaning and sterilization validation

●Reduces cross-contamination risk between batches

●Flexible storage for changing production needs

●Compact storage footprint with high-capacity options

●Lower total cost of ownership than reusable tanks

 

 

 

Our storage bags are engineered for reliable liquid containment:

●USP Class VI biopharmaceutical film with low dissolution and high cleanliness

●100% integrity testing for leak-free performance

●Gamma-sterilizable for aseptic use

●Custom ports, tubing, filters and connectors

●Available in a wide range of sizes and configurations

 

 

 

Single-use storage bags support many bioprocess steps:

●Media and buffer storage

●Intermediate and in-process liquid storage

●Harvest and pool storage

●Liquid transport between facilities

●Powder transfer and liquid handling systems
