Drugs and vaccines are commonly provided in vials.

Since transfer from a vial to an injection system is required, some additional volume is filled in the vial to account for dead space in syringes and needles – this additional volume is overfill.

In applications involving small volumes, the overfill can be significantly larger than the indicated volume; this creates waste (unused drug or vaccine) and results in higher costs.

Overfill problem is cumulative in multi-dose vials (e.g., vaccines)

ELDO™ technology helps utilize this overfill and prevent waste.
