These GMP Cell Expansion Bags provide a closed system solution for sterile, contamination free cell culture and expansion in biopharmaceutical applications. Designed for optimal oxygen and CO₂ exchange, these bags support cell viability and expansion while minimizing water loss. The integrated polycarbonate/silicone (PC/SL) needle valve and high density polyethylene (HDPE) cap allow for secure, aseptic fluid handling in sensitive cell cultures. Closed System Design – Reduces contamination risks compared to traditional culture vessels. Needle Valve (PC/SL) – Integrated polycarbonate/silicone valve for precise, aseptic sampling. HDPE Cap – Ensures a secure and contamination resistant seal. Non Pyrogenic & Non Cytotoxic – Safe for sensitive cell cultures with no endotoxin contamination. DNase/RNase Free & Human DNA Free – Prevents nucleic acid contamination, ensuring reliable results. Minimal Water Loss – Low water permeability prevents evaporation and maintains culture stability.
