Meet All Your Liquid Storage and Transportation Needs
With over 10 years of experience in disposable solutions, LePure Biotech utilizes multi-layer coextrusion membranes independently developed by LePure Biotech for the production of LeKrius Liquid Storage Bags, including 2D, 2.5D, and 3D types. The standard system covers volume specifications ranging from 5ml to 2500L and can provide highly customized products.
Thanks to LeKrius Bioprocess Membranes, each of our sterile liquid storage bags ensures extremely low gas permeability, good physical strength, wide chemical compatibility, and biological compatibility, as well as stability and advantages in cell growth. A stable supply chain and quality control system ensure batch-to-batch consistency, providing safe and convenient storage and transportation solutions for your critical liquids.

Comprehensive Quality Control System for Production Safety
The LeKrius membrane is produced in a Class D cleanroom. To ensure safety, we continuously conduct dynamic environmental monitoring during the production of the LeKrius membrane.
Test data indicates that the air environment around the coextrusion membrane equipment, including the quantity of dust particles and settled microorganisms, meets dynamic Class C standards.
Additionally, every step of the process bag manufacturing undergoes real-time monitoring. These measures are implemented to ensure the quality and safety of the product.
