Vetter Lyo-Ject® is the dual-chamber syringe and V-LK® the dual-chamber cartridge for lyophilized drugs. The dual-chamber syringe Vetter Lyo-Ject® was designed specifically for sensitive drugs requiring lyophilization to maintain their desired shelf life. One of the two chambers contains the lyophilized active drug, the other the diluent. The contents of the two chambers are mixed directly before use. This all-in-one concept increases dosage accuracy and ease of handling. It also reduces the overfill requirement for Lyo-Ject®, which results in less drug loss.
