Vial Adapters

The solution for quick & safe transfer from vials

Vial adapters are a cost-effective solution for the safe and rapid transfer and reconstitution of drugs between vials and syringes. Vial adapter spike technology provides a reproducible engineered depth

for drug and diluent aspiration, which greatly reduces the end-user variability associated with traditional needle aspirations and helps minimize vial overfill.

Vial Adapter

  • Reduces exposure to needle-stick injuries
  • Requires fewer steps, parts and sharps
  • Helps reduce costly overfill requirements
  • Options for siliconized spike to reduce insertion force and in-line fluid path filters to reduce particle transfer


Vial adapters are 510(k) cleared by the United States Food and Drug Administration and carries the CE mark.
