Partially-Filled Design & Additive Capacity

Unlike standard Fleboflex bags that are filled to their labeled volume, Fleboflex Luer bags are intentionally partially filled — leaving significant headroom for additives. This design is purpose-built for compounding environments where multiple medications, vitamins, or minerals are added to a single base solution.

Additive volume capacity (maximum volume at 50 mbar pressure): 50/100 mL container holds up to 136 mL of additives; 100/250 mL holds up to 289 mL; 250/500 mL holds up to 422 mL; 500/1000 mL holds up to 639 mL. These are validated maximums — always confirm that your total compounded volume does not exceed the container's maximum removable volume.

Maximum removable volumes: 50/100 mL = 187 mL; 100/250 mL = 394 mL; 250/500 mL = 677 mL; 500/1000 mL = 1,139 mL. Residual volume (fluid remaining after administration) ranges from 0.2-2.6 mL depending on container size. Air volume inside ranges from 4-30 mL depending on size.

For wellness infusion clinics, the partially-filled design means you can start with a 100/250 mL Luer bag (100 mL of saline) and add up to 289 mL of vitamin/mineral concentrates, glutathione, NAD+, or other additives — all through the single Luer port, without any needle punctures, with room to spare.

Container selection guide: Use the 50/100 mL for small IV pushes and single-additive protocols. Use 100/250 mL for standard multi-vitamin wellness drips. Use 250/500 mL for hydration-plus-additive protocols. Use 500/1000 mL for high-volume hydration with multiple additives or extended infusion sessions.
